Description

The invention relates to a splice module for connecting an optical fiber to an optical fiber coupling using a splice connection between the optical fiber and a pigtail connection conductor connected to the optical fiber coupling, so that end sections of the optical fiber and the pigtail connection conductor are connected to one another to form a spliced connection section , wherein the splice module has a carrier on which a splice connection holder for holding the splice connection section and/or a conductor guide arrangement for guiding the optical fiber and/or the pigtail connection conductor is arranged, the conductor guide arrangement having at least one curved guide section for guiding the optical fiber or the pigtail in a curved manner Includes connecting conductor with a predetermined minimum radius for limiting attenuation in the respective conductor, wherein on a side edge region of the splice module, a bearing arrangement for pivotable bearings of the splice module is arranged on a splice module base about a pivot axis which extends parallel to a base plane of the carrier, in which the carrier has its greatest surface area. Furthermore, the invention relates to a splice module arrangement which has at least one such splice module

The carrier of the splice module, for example a splice cassette, can thus be designed, for example, in the manner of a plate which is pivotably mounted on a splice module base. Several splice modules can be pivoted next to one another on the splice module base, so that pivoting one or more splice modules frees up a space between adjacent splice modules, so that, for example, the carrier of a splice module is accessible for making a line connection or other similar assembly work. Such splice modules are used, for example, in house connections, in splice sleeves or the like.

The splice cassette or the splice module thus enable an optical fiber to be connected to a pigtail connection conductor, at the end of which an optical fiber coupling is arranged. The fiber optic coupling then enables a connection cable to be connected, for example. The fiber optic coupler is typically adjacent to the splice module socket where it is conveniently accessible for fiber optic connection.

[0004] However, the wiring, in particular of the pigtail connection conductor, is cumbersome with the known technology.

It is therefore the object of the present invention to provide an improved splicing module.

To solve the problem is provided in a splice module of the type mentioned that at least one coupling holder for holding the optical fiber coupling and / or the optical fiber coupling is arranged on the carrier.

The handling of the splice module, especially when several splice modules are arranged on a splice module base, is significantly simplified. The at least one fiber optic coupling is available directly on the splice module for connecting a connection cable. The pigtail connection conductor is held on the carrier of the splice module, preferably even covered by a cover of the splice module, so that the optical fiber or a cable with the optical fiber leads into the splice module, but otherwise no cables, lines or the like from the interior of the splice module are to be led out into the environment. In addition, the pigtail connection conductor, which does not run freely in the vicinity of the splice module but is arranged directly on the carrier of the splice module, can be provided with minimal insulation since it is not or only insignificantly exposed to environmental influences, mechanical damage or the like.

The splice module can readily have a plurality of optical fiber couplings and/or a plurality of coupling holders suitable for this purpose. Furthermore, the splicing module can also be provided for connecting a plurality of optical fibers to optical fiber couplings. For example, the splicing module has at least two cable inlets for optical waveguides, preferably arranged on opposite sides.

If several coupling holders and / or several optical fiber couplings are present, they are preferably arranged in one plane.

For example, it is advantageous if the coupling mounts and/or optical fiber couplings are arranged in the area of the base plane or on the base plane of the carrier of the splice module.

[0011] In a simple embodiment, the splicing module, in particular its carrier, can be designed, for example, in the manner of a card, cassette or plate.

However, a housing-like configuration or a plate-shaped carrier, in front of which side walls protrude, are advantageous. In the case of the splice module, it is therefore advantageously provided that it has a module housing with a base body that forms the carrier and on which the conductor guide arrangement and/or the splice connection holder is/are arranged.

It is advantageous if the splice connection holder is arranged in a stationary manner on the carrier, in particular on its base body. The splice connection holder and the carrier or its base body are preferably firmly connected to one another, for example in one piece and/or firmly connected to one another by fixed fixing, for example a snap-in fixing, a lock or the like.

It when the splice module has only a single carrier and / or only a single base body is also advantageous. It is advantageous if both the splice connection holder and the at least one coupling holder or several coupling holders are arranged in a stationary manner on the carrier or floor body.

The carrier or the module housing of the splice module is preferably in one piece or in one piece.

The carrier, in particular the module housing, is preferably made of plastic, in particular of an electrically insulating plastic. Of course, other materials can also be used, also in combination, for example metal, in particular steel. For example, it is also possible for the carrier itself to be made of metal, in particular also the at least one coupling holder, while components arranged on the carrier, for example side walls, the splice connection holder, components of the conductor routing arrangement, for example guide projections, guide walls and the like, are made of metal plastic can exist. It is advantageous if the at least one coupling holder and a base plate of the carrier are in one piece or in one piece.

It is advantageous if the splice module has an in particular plate-like cover for covering an interior of the module housing, the cover being located opposite the base body when it is arranged on the module housing. The cover and the base body delimit an interior space in which, for example, the at least one pigtail connection cable is arranged in a protected manner. The cover completely or partially covers the interior of the module housing. Fastening means, for example locking means or the like, are advantageously used to hold the cover on the module housing. The lid preferably also covers the splice connection holder. The splice connection holder is preferably arranged on the base body and can be covered by the cover. The splicing module preferably has only a single cover. The splice connection holder is preferably not arranged on the lid. It is advantageous if peripheral walls protrude in front of the carrier, in particular the bottom body. The peripheral walls form, for example, lateral side walls delimiting an interior space of the carrier or module housing.

The peripheral walls protrude in front of the floor body and delimit an interior space. It is advantageous if the splice connection holder and/or the conductor guide arrangement is arranged in a stationary manner in the interior.

The at least one coupling holder, the splice connection holder and the conductor guide arrangement are advantageously arranged one behind the other in a row direction and in a common plane.

It is particularly advantageous if the at least one coupling holder is not covered or can be covered by the splice connection holder.

It is preferred if the at least one coupling holder and/or the optical fiber coupling is arranged on at least one peripheral wall which projects in front of the carrier, for example the base body. For example, the clutch mount is provided as an opening on the peripheral wall or side wall.

The at least one coupling holder includes, for example, a plug-in receptacle for plugging in the optical fiber coupling. For example, the coupling holder includes a plug-in axis, along which the optical fiber coupling can be inserted into the coupling holder, but spaced support walls on which a coupling housing of the optical fiber coupling is positively supported transversely to the direction of insertion. For example, push-through openings with an inner contour are provided on the support walls, which correspond to an outer peripheral contour of the clutch housing, so that this can be supported in a form-fitting manner on all sides.

Furthermore, it is advantageous if the coupling holder has at least one rear gripping surface or support surface for supporting a rear gripping body, for example a catch, a bolt, a support projection or the like, which protrudes from a coupling housing of the optical fiber coupling. For example, the coupling housing has a supporting projection on opposite sides, in particular a resilient supporting projection or a catch, which engages behind the supporting surface or rear gripping surface of the coupling holder when the optical fiber coupling is inserted into the coupling holder.

The coupling holder comprises, for example, a receiving chamber into which a coupling housing of the optical fiber coupling can be inserted.

In the case of the splice module, it is advantageous if it has at least two or more coupling holders and/or optical fiber couplings, in particular arranged next to one another in a row. It is preferred if the coupling housings of the optical waveguide couplings have a flat shape and are arranged lying flat next to one another in the row arrangement. It is preferred if a respective optical waveguide coupling has two connections for an optical waveguide cable, for example plug-in connections, the connections being arranged next to one another in the row direction.

It is advantageous if the at least one coupling holder or the optical fiber coupling, in particular a row arrangement of coupling holders or optical fiber couplings arranged next to one another, and the bearing arrangement on opposite and/or mutually angled, in particular right-angled, side edge regions of the splicing module or its carrier are arranged. It is of course possible for one or more coupling mounts and/or optical fiber couplings to be arranged on a plurality of side edge regions of the carrier. For example, the coupling mounts or optical fiber couplings can run around the carrier in a U-shape.

The splice connection holder comprises, for example, a plurality of, in particular U-shaped and/or trough-like, receptacles arranged next to one another for inserting splice connection sections. For example, the recordings are comb-like. A respective splice connection section is preferably arranged in a protective body, for example in a protective housing, a grommet, a shrink tube or the like. The receptacles of the splice connection holder are preferably designed for latching or clamping the splice connection section or a protective body arranged thereon in the receptacle.

It is preferred if the splice connection holder is releasably attached to the carrier, for example by a plug connection, snap-in connection, screw connection or the like. The splice connection holder is, for example, plate-like

It is preferably provided that the splice connection holder has, for example, receptacles for first splice connection sections and second splice connection sections on opposite sides, the first and second splice connection sections differing from one another geometrically, for example. For example, the first splice connection sections can be provided for accommodating first protective bodies, the second splice connection sections for accommodating second protective bodies which differ geometrically from the first protective bodies, for example have a larger diameter or the like. Such a splice connection holder can, for example, be mounted on the carrier in mutually opposite positions, so that either the receptacles for the first splice connection sections or the receptacles for the second splice connection sections can be used.

It is preferably provided in the splice module that the conductor routing arrangement has line receptacles for receiving the pigtail connection conductor and/or the optical waveguide, which delimit an interior space in which the splice connection holder is arranged. The line receptacles therefore run around the splice connection holder, for example, so that the conductors laid or received in the respective line receptacles, ie the pigtail connection conductor or the optical waveguide or both, are routed around the splice connection holder.

It is preferably provided in the splicing module that the conductor guide arrangement, in particular curved guide sections, has loop-shaped and/or curved guides for guiding the pigtail connection conductor and/or the optical waveguide around the splice connection holder.

The splice connection holder is preferably arranged between the side edge area of the splice module having the bearing arrangement and an opposite side edge area of the splice module running parallel thereto. The at least one coupling holder and/or at least one optical fiber coupling is preferably located on the side edge area of the splicing module that is opposite to the bearing arrangement.

It is advantageous if the splice module has a plurality of, for example at least two, management planes for guiding the respective lines. The line levels are preferably arranged in layers with respect to the base level of the carrier.

At least two, preferably all, management planes are advantageously immovable relative to each other. Furthermore, it is advantageous if the splice connection holder is stationary with respect to at least two, preferably all, guide levels.

The conductor routing arrangement expediently comprises a first guide level on the bottom, in particular for receiving a line section of the pigtail connection conductor to that provided for the optical fiber coupling, above a bottom wall of the splicing module, and a second guide level at a greater distance from the bottom wall. The second management level is advantageously provided for guiding line sections leading to the splice connection holder.

Thus, for example, pigtail connection conductors leading from the optical fiber couplings arranged stationary on the splice module can be routed in the first management level on the ground side. It is advantageous if a first section of a respective pigtail connection conductor is arranged in the first guide level on the ground, while a second section of the pigtail connection conductor, which is more remote from the optical fiber coupling and is intended for connection to optical fibers, for example, i.e. to the splice connection holder lead soil, is arranged in the second management level, which is more easily accessible for the operator. Thus, a line reserve or cable reserve of the pigtail connecting conductor is arranged in the second routing level, so to speak, and can easily be removed from the splicing module for splicing to the optical waveguide.

In the case of the splice module, it is advantageously provided that the splice connection holder is arranged in the second management level, in particular in a stationary manner. Thus, for example, the power reserves of the optical waveguide and/or pigtail connection conductor can be routed to the splice connection holder in the second management level.

The conductor guide arrangement can, for example, have one or more support projections which protrude in front of the bottom wall. Guide channels or receiving channels for guiding or receiving sections of the pigtail connection conductor or optical waveguide can be provided between the supporting projections. Furthermore, it is possible for the conductor routing arrangement to have support walls in a manner known per se. The already mentioned peripheral side walls or side walls of the module housing can also form part of the conductor routing arrangement.

It is advantageous if supporting projections of the conductor guide arrangement protrude in front of the bottom wall, between which at least one guide channel of the first guide level on the bottom runs and on whose sides facing away from the bottom wall or free end sides support surfaces are provided to provide the second guide level. Thus, so to speak, the gaps between the support projections for line routing are provided in the first guide level, while at the free end regions of the support projections there are, so to speak, support platforms or support surfaces for providing the second guide level.

[0040] In order to reliably hold line sections of the at least one pigtail connection conductor or of the at least one optical waveguide, the conductor guide arrangement advantageously has one or more hold-down elements. For example, it is advantageous if the conductor routing arrangement has hook-like hold-down devices for holding the optical waveguide and/or the pigtail connection conductor in an interior space and/or in an opposite position in a bottom wall of the splicing module. A respective hold-down device or hook-shaped hold-down device can be provided, for example, on a free end region of one or more of the aforementioned support projections, so that sections of the respective conductor resting on the support surface of the support projection are held by the hold-down device on the support projection.

In a simple form, the splicing module may not contain the pigtail connection conductor and the optical fiber coupler. The splice module can thus be fitted later, for example.

However, prefabrication is preferred. The pigtail connection conductor and/or the optical fiber coupling advantageously forms part of the splice module. For example, several fiber optic couplings and several pigtail connection conductors are arranged on the carrier, so that the splice module is ready for installation, so to speak, for connection to one or more optical fibers.

[0043] It is advantageous if the pigtail connection conductor runs in an anti-kink sleeve that protrudes in front of the optical fiber coupling. For example, the anti-kink sleeve is oriented along a plug-in axis, along which a plug-in element can be plugged into the optical fiber coupling.

The at least one pigtail connection conductor is protected from environmental influences by the splice module, in particular its module housing. The pigtail connection conductor advantageously contains an optical fiber which has an insulating coating, in particular a colored one, and is arranged in a cable jacket in a connection area which is connected to the optical fiber coupling or is intended for connection to the optical fiber coupling. The section with the non-colored or colored insulating coating serves, for example, for connection to the optical waveguide.

It is preferred if a length of the light guide in the cable sheath is at least ten times greater, preferably 20 times greater than a length of the light guide outside of the cable sheath. Consequently, the cable sheath is short. The cable sheath can be accommodated in the anti-kink sleeve already mentioned.

It is advantageous if the light guide runs in the conductor guide arrangement essentially or exclusively outside of the cable sheath. The light guide of the pigtail connection cable, starting from the light waveguide coupling, can first be arranged in the splice module inside the anti-kink sleeve, then in the cable jacket and then freely, so to speak, isolated from the environment only by its insulating coating. The portion of the light guide that is only coated with the insulating coating is extremely flexible and therefore easily accessible for assembly work, in particular for connection to the light waveguide that is brought to the splice module from the outside.

The bearing arrangement of the splice module is preferably designed and provided for detachable mounting on the splice module base. For example, plug-in assembly on the splice module base is advantageous. However, it is quite conceivable that the splice module is held captive on the splice module base, for example by bearing elements pivotably mounted on the splice module base, which cannot be removed from the splice module base or can only be removed by an assembly process, for example screw assembly.

[0048] It is preferred if the bearing arrangement comprises, in particular, bearing axis elements arranged integrally on a module housing of the splicing module. The bearing axis elements can be plugged into bearing mounts, bearing grooves, on the splice module base, for example. The grooves are provided, for example, in a resilient bearing projections into which the bearing axis elements of the module housing can engage.

The splice module can form part of a splice module arrangement. The splice module arrangement comprises, for example, one or more splice modules according to the invention. The splice module arrangement also includes a splice module base with a bearing receptacle for receiving the bearing arrangement of the at least one splice module, so that the at least one splice module is mounted on the splice module base so that it can pivot about the pivot axis.

Preferably, at least one pivot stop is arranged on the at least one splice module and/or on the splice module base to limit the pivot movement of the splice module with respect to the splice module base to a pivot angle defined by the at least one pivot stop. Thus, for example, a pivoting angle of the splicing module with respect to the splicing module base can be limited to approximately 35-55°.

It is preferably provided that the splice module base has at least two bearing receptacles arranged in a row axis for the pivotable mounting of the at least one splice module and a further splice module, the splice modules being arranged about pivot axes which are parallel to one another and run in particular at right angles transversely to the row axis the bearing mounts are pivoted independently of one another in a fan-like manner, so that one splice module can be pivoted away from the other splice module and there is an angular distance between the base planes of the splice modules in which the splice connection holder of at least one of the splice modules is accessible. One or more of the splice modules are, for example, splice modules according to the invention. However, it is also possible for other splice modules that are not according to the invention to be pivotably mounted on the splice module base, for example splice modules that only allow a pigtail connection conductor to be spliced to an optical fiber, but do not have an optical fiber coupling or coupling holder for it.

In the case of the splice module arrangement, it is preferably provided that it has a protective housing in which the splice module base and the at least one splice module are arranged and/or that it forms part of a splice sleeve. The protective housing can, for example, comprise a base that is suitable for wall mounting in a building and can be closed by a cover of the protective housing. The splice module base is preferably located on or formed by the floor. It is also advantageous for a splice sleeve if it has a so-called base on which the splice module base is arranged, this base being closable by a hood housing.

An embodiment of the invention is explained below with reference to the drawing. 1 shows a perspective oblique view of a splice module arrangement with two splice modules, FIG. 2 shows a detail D1 from FIG. 1 to illustrate the bearing arrangement, FIG. 3 shows a splice module according to FIG. 1 in a perspective oblique view from the front, FIG Figure 5 shows a detail enlargement D2 from Figure 4.

A splice module arrangement 10 comprises a splice module base 20 on which splice modules 40, 40B, which are structurally identical and are therefore only provided with the reference number 40 in the following description, in a partially simplified manner. The splice module base 20 is advantageously accommodated in a schematically indicated protective housing 11, in particular a protective hood of a splice sleeve or a domestic connection device. However, the splice module base 20 can also be arranged on a so-called rack or frame.

The splice module base 20 comprises a carrier body 21 with a bottom wall 22, from which side walls 23 protrude at an angle, for example at right angles. Between the side walls 23 is a bearing body 30 or a bearing arrangement 30, which can be arranged integrally with the bottom wall 22, with a series arrangement of a plurality of bearing receptacles 31 for pivotally supporting the splice modules 40, 40B and further or other splice modules, which are not shown in the drawing. arranged.

The splice modules 40, 40B are mounted on the splice module base 20 so as to be pivotable about pivot axes S1, S2. The pivot axes S1, S2 run parallel to one another.

In order to guide cables, optical waveguides or the like from the vicinity of the splice module base 20 to the splice modules 40B, the splice module base 20 has guide receptacles 26 which are delimited, for example, by guide projections 24, 25 which are at a distance from the bottom wall 22 and thus delimit a channel for receiving lines. The guide projections 24 project, for example, from the side walls 23 in the direction of the bearing receptacles 31 and thus the splicing modules 40, while the guide projections 25 project in the opposite direction from the side of the bearing body 30 toward the guide projections 24. Between the guide projections 24, 25 there are distances through which lines can be inserted into the guide receptacles 26.

The splice modules 40 have carriers 41 on which a bearing assembly 50 for pivotally mounting the splice modules 40 on the splice module base 20 is arranged. The bearing assembly 50 is disposed on a side edge portion 48 of a respective beam 41 and includes bearing axle members 51 extending between bearing bosses 52, 53 projecting in front of the beam 41 and integrally connected thereto. The bearing axis elements 51 extend along the pivot axes S1, S2 and can be snapped into the bearing mounts 31, so to speak.

The bearing seats 31 are provided between bearing projections 32 projecting in front of the bottom wall 22. As shown in FIG. The bearing projections 32 are designed, for example, in the manner of tabs or plate-like projections. Introductory bevels 33 are preferably provided on the free end regions of the bearing projections 32, along which the bearing axle elements 51 can slide for latching into the bearing receptacles 31 and can displace the bearing projections 32 away from one another.

Between mutually parallel rows 35 of bearing mounts 31 there is a projection which projects into a mount 54 of the bearing assembly 50 .

Row axes of rows 35 are orthogonal to pivot axes S1, S2.

The bearing projections 52, 53 are designed in the manner of bearing blocks. The bearing axle elements 51 are preferably in one piece with the bearing projections 52, 53.

The carrier 41 is preferably designed as a module housing 47 or has one. The carrier 41 includes a plate-like bottom body 42 from which peripheral walls 43A project.

The peripheral walls 43A include, for example, opposite side walls 43 extending with arcuate portions 44 toward the side edge portion 48. As shown in FIG. Between the side walls 43, on the side of the carrier 41 opposite the side edge region 48, there extends a front side wall 45, on which a plurality of optical fiber couplings 90 are arranged, which can be distinguished as optical fiber couplings 90A, 90B, 90C, 90D, 90E, 90F.

The side walls 43, in particular their arcuate sections 44, extend up to a rear side wall 46 on which the bearing arrangement 50 is arranged.

Thus, the optical fiber couplers 90 and the side edge portion 48 are arranged on opposite sides of the carrier 41 so that the optical fiber couplers 90 are conveniently accessible.

As indicated schematically with an optical waveguide coupling 90G, it would also be possible, for example, for an optical waveguide coupling to be arranged on one or both of the side walls 43 .

The optical fiber couplings 90 arranged on the front side wall 45 or the optical fiber couplings 90 arranged on a side wall 43 are easily accessible, for example to plug in a plug 151 of an optical fiber connecting line 150 with an optical fiber 152. The fiber optic connection line 150 is used, for example, for data transmission in a building.

The bottom body 42 extends in a base plane G of the carrier 41, in which this has its greatest surface area. The respective pivot axis S1, S2 runs parallel to the respective base plane G of the splicing module 40, 40B. The splicing modules 40, 40B can thus be pivoted away from one another in a fan-like manner, so that an interior space 49, for example of the module housing 47 of the splicing module 40 as shown in FIG. 1, is easily accessible, for example for the splicing of optical fibers explained below. However, it should be mentioned that the splice modules 40, 40B can be removed from the splice module base 20 at any time in order to carry out the assembly work and/or splice work explained below.

A pivot stop 50A is provided on the splice module 40, for example, which limits pivoting of the splice module 40 on the splice module base 20 about the respective pivot axis S1 or S2 to a predetermined pivot angle, for example approximately 45°. The pivot stop 50A is provided by an inclined surface on the rear side wall 46, for example.

The splicing module 40, 40B is preferably pre-assembled, so to speak. The optical waveguide couplings 90A, 90B, 90C, 90D, 90E, 90F are preferably already mounted on the carrier 41 before the optical waveguides are spliced, namely in coupling holders 80A, 80B, 80C, 80D, 80E, 80F, which are subsequently referred to collectively as coupling holder 80 are described. The coupling brackets 80A, 80B, 80C, 80D, 80E, 80F are arranged on the front side wall 45. As shown in FIG.

However, it would also be possible, in particular due to the simple plug-in assembly, to introduce the optical fiber couplings 90A, 90B, 90C, 90D, 90E, 90F into the coupling holders 80A, 80B, 80C, 80D, 80E, 80F only when the Splicing of the pigtail connecting line 170 to the optical waveguide 100 has already taken place.

The coupling holders 80A, 80B, 80C, 80D, 80E, 80F and/or the optical fiber couplings 90A, 90B, 90C, 90D, 90E, 90F are arranged in a row axis R next to one another. The coupler mounts 80A, 80B, 80C, 80D, 80E, 80F form a row assembly 85. The row axis R is parallel to the ground plane G. The row axis R is parallel to a respective pivot axis S1 or S2.

The fiber optic couplers 90 have a coupler housing 91 which, on its free side protruding in front of the side wall 45 , has sockets 92 for plugging in, for example, a plug 151 of a fiber optic cable 150 . Thus each optical fiber coupling 90 serves to connect two optical fiber connection lines 150 to the splicing module 40 . The plug-in receptacles 92 are arranged next to one another along the row axis R.

The coupling holders 80 have plug-in receptacles 89 with receiving chambers or holder receptacles 81 which are provided between the front side wall 45 and a wall 83 running parallel thereto. Between the front side wall 45 and the wall 83, the mounting receptacles 81 delimiting side walls 82 are provided.

Furthermore, a cover wall or support wall 87 extends in the manner of a belt in the area of the front side wall 45 between the side walls 43 and delimits the mounting receptacles 41.

The side walls 82, but also the wall 83 and/or the front side wall 45 provide rear gripping surfaces or support surfaces for latching projections 95 of the optical fiber couplings 90, which latch when a respective coupling housing 91 is inserted into a coupling holder 80 with the latter . For example, the latching projections 95 are designed in the manner of resilient tabs or the like in a manner known per se. The latching projections 95 project in front of side walls 94 of the clutch housing 91 .

Push-through openings 84, 86 are provided on the wall 83 and the front side wall 45, through which a respective optical fiber coupling 90, in particular its coupling housing 91, can be pushed through, with the locking projections 95 locking in the chamber-like holding receptacles 81. The through-openings 84, 86 have an inner peripheral geometry that correlates with the outer peripheral geometry of the clutch housing 91, so that they are received in the through-openings 84, 86 in a form-fitting manner.

Indicators or labels 88 are preferably assigned to the coupling holders in 80, with which the individual coupling holders 80A, 80B, 80C, 80D, 80E, 80F and/or the optical fiber couplings 90A, 90B, 90C, 90D, 90E, 90F, in particular their respective plug-in receptacles 92 are individually labeled or indexed. The indicators or inscriptions 88 are preferably located on the top wall or bulkhead 87 .

The coupling housings 91 have, on their sides opposite to the plug-in receptacles 92, connections 93 to which a pigtail connection conductor 170 is connected in each case. A kink protection sleeve 96, in which the pigtail connection conductor 170 runs, is preferably firmly connected to a respective connection 93.

The pigtail connection conductors 170, of which only one is shown as an example, have an optical fiber 171, from which a section or connection area connected to the optical fiber coupling 90 runs in a cable jacket 172. The cable jacket 172 is preferably permanently connected to the anti-kink sleeve 96 and/or runs in the anti-kink sleeve 96.

However, the cable jackets 172 are very short and only extend as far as approximately a conductor guide arrangement 60, by means of which the individual optical fibers 171 are guided or accommodated in an orderly manner in the interior space 49 of the splice module 40.

The light guide 171 is preferably provided with an insulating coating, in particular a colored insulating coating, but this is not visible in the drawing. Thus, each optical fiber 171 is color coded and conveniently identifiable within the fiber routing assembly 60 or in the area of a splice fixture 55, respectively. It is also advantageous if the cable jacket 172 has the same color as the insulating coating of the light guide 171 accommodated in it.

In each case one optical fiber 171 is namely to be connected to an optical fiber 100 which is routed from the outside of the splicing module 40 into its interior 49 . Of course, the optical waveguide 100 can include a plurality of optical fibers, each of which is to be connected to an optical fiber 171 . Only a single light guide is shown as an example.

The optical fiber 171 of the pigtail connection conductor 170 is thus connected to the optical fiber 100 at its end region facing away from the optical fiber coupling 90, namely by means of a spliced connection, so that the two conductors form a spliced connection section 105.

The splice connection section 105 is advantageously protected by a protective body, in particular a shrink tube or the like, but this is not shown in the drawing.

The splice connection section 105, in particular a protective body encasing it, can be inserted, in particular latched or clamped, into a receiving channel 57 of the splice connection holder 55, for example.

The spliced connection holder 55 has a plurality of receiving grooves 57 running parallel to one another for receiving a spliced connection section 105 in each case.

The receiving grooves 57 run, for example, parallel to the row axis R and/or parallel to the pivot axis S1, S2, although this is not absolutely necessary.

The receiving grooves 57 are provided on a plate body 56 of the splice connection holder 55. As shown in FIG. The plate body 56 has an arrangement of a plurality of receiving grooves 57 on mutually opposite, large-area sides or flat sides, which, however, can have different widths or otherwise different geometries. The plate body 56 can be releasably mounted on the carrier 41 in mutually opposite orientations so that the receiving grooves 57 required for receiving splice connection sections 105 are available in each case. The plate body 56 has, for example, a holder 58 which, for example, comprises a receiving opening into which a retaining projection 59 protruding from the carrier 41, in particular the base body 42, engages, in particular in the manner of a latching connection.

The conductor guide arrangement 60 comprises a row of supporting projections 61, 62 protruding from the base body 42, between which supporting projections 63 are arranged.

Row arrangements of the respective support projections 61, 62 and 63 advantageously run along a row axis which is parallel to the row axis R.

The support projections 61, 62 are arranged in a row next to one another and face the optical waveguide couplings 90. FIG.

The supporting projections 63 are arranged at a greater distance from the optical waveguide couplings 90 .

Guide receptacles 64 for receiving pigtail connection conductors 170 are formed between the supporting projections 61, 62 and the supporting projections 63 that are further away from the optical waveguide couplings 90 .

The guide receptacles 64 run obliquely to a support wall 65 which is opposite the support projections 63 . Between the supporting projections 63 and the supporting wall 65, a channel 66 is formed, which merges into a channel-like curved guide section 67, which is formed between the peripheral walls 43A, specifically, for example, the curved sections 44 of the side walls 43, and a supporting wall 68, which is curved at least in sections, which forms the side wall 43 opposite.

The arc guide portion 67 has a minimum radius of curvature that does not allow the optical fiber received therein to curve beyond a minimum level. The light guide can therefore not be curved more than is specified by the curved guide section 67 . As a result, an attenuation caused by a curvature of the light guide is low.

The pigtail connecting conductors 170 are first routed away from the optical waveguide couplings 90 along the base body 42 or above a base wall 69 in a guide plane E1. The guide receptacles 64, the channel 66 and the sheet guide section 67, for example, run in the guide plane E1.

A guide plane E2, into which the pigtail connection conductors 170 can be guided, is provided at a greater distance from the base body 42. For the sake of simplicity, this is not shown in the drawing. The guide level E2 includes, for example, a support surface 70 which is at a distance from the bottom wall 69 . The support surface 70 is provided, for example, on a kind of pedestal. Supporting walls 71 project in front of the supporting surface 70 and are opposite the supporting walls 68 . Channel-like curved guide sections 72 are thus formed between the support walls 71, 68, which are suitable for accommodating the pigtail connection lines 170 and/or the optical waveguides 100.

Support surfaces 73 on the support projections or on the free end regions of the support projections 61, 62, 63 are in the same plane as the support surface 70. Lines can thus be routed via the channel 66 from the support surface 70 to the support projections 61, 62, 63 be led.

Hold-down devices, in particular hook-shaped hold-down devices, hold the respective lines in the cavities of the conductor routing arrangement 60. For example, in front of the supporting walls 71, 68 hold-down devices 75 protrude into the curved guide sections 72, with insertion slots between the hold-down devices 75 for inserting cables into the curved guide sections 72 available. Furthermore, for example, hook-shaped hold-down devices 76 are advantageously provided on the supporting projections 61-63.

Inlets 74 for optical waveguides 100 are provided on the side edge area 48 . The inlets 74 are preferably located in the guide plane E1 and are provided between the side walls 43 and the rear side wall 46, for example.

A section 101 of an optical fiber 100 is inserted, for example, into one of the inlets 74 and a section 102 extends between the rear side wall 46 and the splice connection holder 55 into that sheet guiding section 72 which is opposite the inlet 74 . There, the optical waveguide 100 is guided in an arc in a section 103 and then runs further over the supporting projections 63 into the opposite arc guide section 72 and out of it in a generous arc with a small radius of curvature to the splice connection holder 55 and thus to the splice connection section 105 in .

It can be seen that the lines of optical fiber 100 and pigtail connecting line 170 are routed in a loop or arc shape around the splice connection holder 55 through the conductor guide arrangement 60, so that on the one hand the splice connection holder 55 is easily accessible and on the other hand the radii of curvature of the lines are small.

A partially schematically indicated, in particular plate-like, cover 12 is preferably provided, with which the interior space 49 can be covered entirely or substantially. The cover 12 can, for example, be clamped, latched or connected in some other way to the peripheral walls 43A. In particular, latching projections or supporting projections 13 are provided for latching the cover 12 to the module housing 47 and/or for supporting the cover 12 . 10 splice module arrangement 60 conductor guide arrangement 11 protective housing 61 support projections 12 cover 62 support projections 13 latching projection 63 support projections 14 64 guide receptacles 15 65 support wall 16 66 channel 17 67 sheet guide section 18 68 support wall 19 69 base wall 20 splice module base 70 support surface 21 carrier body 71 support walls 22 sheet guide base walls 73 support surfaces 24 guide projections 74 inlet 25 guide projections 75 hold-down device 26 guide receptacles 76 hold-down device 30 bearing body 80 coupling holders 31 bearing receptacles 81 holder receptacles 32 bearing projections 82 side walls 33 insertion bevels 83 wall 34 projection 84 through-opening 35 rows 85 row arrangement 86 through-opening 40 40B splice modules 41 carrier 8 8 indicator top wall indicator /Labeling 42 base body 89 socket 43 side walls 43A peripheral wall 90 optical fiber couplings 44 curved sections 91 coupling housing 45 front side wall 92 sockets 46 Rear side wall 93 Line connector 47 Module housing 94 Side walls 48 Side edge area 95 Snap-in projections 49 Interior space 96 Anti-kink grommet 50 Bearing assembly 50A Pivoting stop 100 Optical fiber 51 Bearing axis elements 52 Bearing projections 105 Splice connection section 53 Bearing projections 150 Optical fiber connection line 54 Receptacle 151 Connector 55 Ptailig optical fiber connection bracket 156 Ptailig fiber optic cable 156 Connection conductor 57 receiving grooves 171 light guide 58 holder 172 cable jacket 59 retaining projection
