Description

 The present invention relates to a distribution and patching device for the ends of optical fiber cables, this distributor device being capable of being installed at a fixed station for example, this fixed station having qualities of modularity facilitating great adaptation to the position and size of the components present as well as the interconnection wiring.

 Such a distribution device finds its application in civil devices such as telephone exchanges, brewing centers for video communications or even in military electronic structures intended to equip tactical employment equipment. In these latter applications, the distributing devices must obviously meet the optimum criteria of size, maneuverability, homogeneity, maintainability, in order to allow distribution "on demand" of the optical channels.

 Distribution and stirring or storage devices have already been described, for example French patents 2,577,688, 2,581,769, 2,581,767. However, these various devices do not meet the requirements of adaptability to the different configurations of wiring or large capacities.

 The distributor device of the invention responds to numerous constraints. I1 allows end-to-end maintenance and protection of optical fibers, compliance with minimum bending radii, occasional absorption of extra lengths, accessibility and interchangeability of the connectorized optical cords, great adaptability to different cabling configurations, great ease of implementation as well as many other advantages.

 The invention essentially consists in having a basic modular structure acting as an optical interconnection which tends to be freed from the position and the bulk of the components present as well as the interconnection cables (both electrical and 'optics).

 The optical fiber distribution device of the invention comprises means for connecting and patching a multiplicity of optical fibers, for example from optical cable heads, and, in particular, a rail 1 having a U-shaped profile serving, d firstly, to support the distribution components (2, 3, 4, 5, 6, 7, 9), these distribution components (2, 3, 5, 6, 7, 9) being placed in elevation relative to the rail 1, the optical fibers (FOi) i being capable of being extracted or inserted at any point of said rail 1 or of said distribution components, at the level of the space delimited by the edges of said rail 1 and said component (2, 3 , 5, 6, 7).

 The rail 1 of the invention is provided with at least one row (10 ′, 10 ") of bores 100 placed regularly along a column coaxial with said rail 1.

 In particular, the means 2 (resp. 9) of distribution are essentially formed by a cassette (22, 23, 24, 25) (resp. 92, 93, 94, 95) integral with a module 21 (resp.

91) of thickness greater than the depth of the U of said rail 1, said module 21 (resp. 91) being mounted on a central line 10 (resp. 10 ") of holes 100.

 The cassette (22, 23, 24, 25) (resp. 92, 93, 94, 95) is accessible for extracting or introducing the optical fibers on at least each of its ports 26 (resp. 96) adjacent to said rail 1.

 The cassette 2 of the invention is essentially formed by a base 24 surmounted by gods central coiling sectors 22, said sectors 22 being surrounded by four external coiling guides 23 delimiting an annular sector for receiving optical fibers.

 The cassette 9 of the invention is essentially formed by a base 94 surmounted by two central coiling sectors 92, each central sector 92 being formed by a plurality of elementary sectors (920), each elementary sector t920) cooperating with its symmetrical relative to rail 1 for forming an annular space for receiving the optical fibers, said sectors 92 being surrounded by four external coiling guides 93, said elementary psectors (920) having variable diameters which are substantially non-concentric.

 The optical fibers FOi stored in the cassette (22, 23, 24, 25) (resp. 92, 93, 94, 95) can be extracted according to the invention from the annular sector of reception of the said cassette 2 (resp. 9) at any one of the four accesses 26 (resp. 96) / each access 26 (resp. 96) being delimited by two adjacent coiling guides 23 (resp. 93).

 The cassette 2 of the invention can be equipped with an annex rail 12 set back perpendicular to the main receiving rail 1 in order to protect the optical fibers extracted from the accesses 26 not being located near the rail 1, this configuration giving cassette 2 has a bypass function.

 The device of the invention comprises in particular a plurality of channel separators 4 mounted on at least one central (resp. 10 ") row 10 '(resp. Lateral) of bores 100, each separator 4 being provided with a plurality of cells 41 being in the form of tubular conduits substantially coaxial with said rail 1, said cells 41 receiving the optical fibers through openings 42 also coaxial with said rail 1, each opening 42 serving to introduce or extract the optical fibers placed in each cell 41.

 The device of the invention furthermore comprises a junction box-junction 3 mounted for example on a central file 10 'of bores 100 by means of a module 31 secured to at least one sheath fixing ring 35 34 flexible, each sheath 34 allowing access to a plurality of fibers FOi to said distributor device of the invention.

 The ring 35 as well as the flexible sheath 34 are in particular split according to the invention longitudinally respectively along slots 350 and 340 in order to allow the insertion or the extraction of the optical fibers which they receive from end to end.

 A terminal block module 5 is also mounted according to the invention in excess thickness relative to coral 1, and is made integral with a modular support 52 common to a plurality of terminal blocks 53.

 Two redistribution plates 6 are also placed according to the invention on either side of said module 5 terminal block holder also in excess thickness relative to said rail 1, said plate 6 essentially having the function of grouping and redistributing in a rail 1 the fibers optics connected to one of said terminal blocks 53.

 The modules (5, 6) are supported by at least one rail 1 according to the invention.

 Thus, the dispensing device of the invention comprises means for either inserting the optical fibers at the level of all the components (2, 3, 4, 5, 6, 7, 9), or making them travel in the rail 1 under these components (2, 3, 5, 6, 7, 9).

 Other characteristics and advantages will appear on reading the following description illustrated by drawings.

 It will be noted that the optical fibers to which the distribution device of the invention applies are both fibers of free structure than fibers of tight structure. In the following description, we will simply speak of optical fiber for the sake of simplicity.

FIG. 1 represents an overall diagram of the modular device for distributing and distributing the invention. This device revolves around an optical cable tray in the form of a profile 1 in
U, for example vertical, constituting the basic element of the modular device. This profile 1 is provided with holes 100 for the mechanical fixing of the elements adapting to the optical cable tray. The holes 100 are evenly distributed matrically over the entire surface of this profile 1 with a pitch p chosen appropriately, for example according to threads 10 '(resp. 10 ") central (resp. Lateral) as shown in FIG. 2 .

 In a preferred embodiment of the invention, the pitch is chosen equal to 15 mm.

 The edges of the optical rail 1 are bent in order to clearly delimit a protective space for the optical fibers s and are chosen of appropriate height, as will appear later.

 The pitch and the number of holes 100 is chosen judiciously in order to provide a multiplicity of distribution functions to the profile 1 itself. Thus, in a preferred embodiment of the invention, the rail 1 is approximately 44 mm wide and provided with bores 100 distributed in the two directions with a pitch of 15 mm. This triple file (10 ', 10 ") of longitudinal bores gives the rail 1 particular distribution functions. In fact, the central file 10' allows fixing of various elements such as heightening spacers, distribution cassettes 2 and junction boxes 3 as well as the fixing of the various protective covers, while the two lateral lines 10 "of rD holes allow the fixing of the spacers 51 and 65 for raising the plates of the components (5, 6).

 In the case of components (5, 6), the interior lateral rows are used to free the interior of the rail 1 for the circulation of the optical fibers routed in this rail 1, as well as the fixing of the channel separators 4.

 On this profile 1 can be installed various mechanical receiving elements or unitary wiring distribution according to the wiring requirements. These various mechanical elements for receiving, distributing or mixing are arranged according to the invention in excess thickness with respect to the rail 1, so that the optical fibers can be introduced under these various elements into the curvature of the rail 1 as will appear. later.

 The rail 1 is advantageously made of a metallic material of the stainless steel type. This rail 1 can also be produced in any moldable or extrudable material, such as plastic, such as polycarbonate, nylon, or also in an alloy such as Aluminum, Zamack, etc.

 A protective cover 16 covers the rail 1 and is fixed thereon by means of spacers, not shown, screwed onto the threaded holes 100 available in the central file 10 'of the rail 1.

 In addition, elastomeric tape, not shown, glued to the inside of this rail 1, provides additional and unconstrained support for the fibers flowing in the rail 1.

 FIG. 2 represents the installation of a cassette 2 for distributing a connection box 3 ′ on the modular section 1 of the invention as well as a channel separator 4 as well as the installation of flexible sheaths 34 illustrating a nonlimiting exemplary embodiment of the invention.

 The channel separator 4 is in the form of a perforated bar of a plurality of cells 41 whose number and size are adapted to the required capacity and to the profile 1 in which it is integrated.

 In a preferred embodiment of the invention, these cells 41 shown in section in FIG. 4a have openings 42 towards the outside, said openings 42 being on the side opposite to said rail 1 on which the separator 4 is mounted. In addition, as shown in Figure 4b in front view of said rail 1, these cells 41 are substantially coaxial tubes to said rail 1, the openings 42 also being coaxial to said rail 1. Two essential functions are assigned to them. A first function for holding the optical fibers JTF, F02, each cell 41 being able to group together, for example, twenty optical channels under the same tubular conduit. A second function which is to organize inside the section 1 in U, each cell 41 ma serializing for example six separate optical strands which, by grouping of the channels, allow the realization of a distribution both up and down using the same profile 1 as will appear later. The channel separators 4, such as that shown in Figure 4, are made of a non-aggressive material, for example synthetic, for example polycarbonate in order to effectively maintain and protect the optical fibers. A short distance from the channel separator 4, on the section 1, is placed a cassette 2, the sectional view along AA 'is shown in Figure 3. This cassette 2 is fixed on the modular rail 1 along the central file 10 'of bores 100 thanks to a spacer 21, so that the cassette 2 is placed in excess thickness relative to the rail 1. In fact, the cassette 2 is formed by a base 24 integral with the spacer 21. L' spacer 21 extends in the center of the rail 1 and makes it possible to precisely fix the cassette 2 to the rail 1 at a distance from the bottom of the rail 1 greater than that of the edges of the rail 1. Two screws 25 allow to fix the cassette 2 through ltentretoise 21 on the central file 10 'of holes 100 of the rail 1. Two identical central coiling sectors 22 are placed on this base 24 symmetrically with respect to the rail 1 and fixed by means of two screws 13 on this base 24. Four guides 23 external coils are placed at each corner of the base 24 and co operate with the guides 23 to delimit an annular space for receiving the optical fiber extra lengths. Thus, Figures 3 and 5 which show a cross-sectional view of the rail represent the cassette 2 also in section but respectively along a line AA '(10') of bores and a column BB '(10 ") of bores. The fiber optic F02, placed in the cassette 2, is therefore represented in section in FIGS. 3 and 5 coming from one of the four directions of rising rail, descending rail, or from one of the two directions perpendicular to rail 1, the latter two the directions being placed in the same plane, since the geometry of the cassette 2 easily allows the installation of an annex rail 12, this rail 12 can for example be fixed by means of a screw 14 under the base 24. This rail 12 is similar to rail 1, that is to say a double line distribution with a column of bores 120 and raised edges in a U-shape in order to protect the fibers which it has to distribute. separator 4, are then placed on the annex rail 12 in number sufficient to effectively hold the optical fibers.

 Thus, if the center of the cassette 2 is called 0, the optical fibers can, according to the invention, be received by means of the coiling cassette 2 and be extracted from the cassette 2, either in one of the two directions OB, OB 'descending or rising from the rail 1, either in one of the two directions OA, OA' of the annex rail 12 as shown in FIG. 2 by means of an access 26, each access 26 being delimited by two adjacent coiling guides 23 Thus, any optical fiber passing through the annular space for receiving the cassette 2 can be extracted, either at its entry access 26 (which gives it a 360-degree derivation function), or at its level. access 26 placed at 1800 of the entry access with respect to the center O of the cassette, or again at one of the two lateral accesses (which gives it a bypass function at 900 or 2700.

 The optical fibers traveling in the rail 1 can still continue their direct path inside the rail 1 under the cassette.

 FIG. 6 represents an alternative embodiment of the distribution cassette of the invention. This cassette 9 is essentially formed by a base 94 supporting central coiling sectors 92, as for cassette 2, placed symmetrically with respect to the rail 1. However, instead of the coiling sectors 92 delimiting a single annular receiving space for optical fibers in cooperation with the four external coiling guides 93 placed at each angle of the base 94, the coiling sectors 92 are formed of a plurality of elementary sectors (92P'PEN. Each half-sector 92 cooperates with its symmetrical with respect to rail 1 to form an annular receiving space for optical fibers. Each half-sector theme 92p corresponds to a ring of own diameter Dt. These different rings are not concentric but are substantially centered in the vicinity of rail 1 so that one can choose the receiving ring t in which one wishes to store a given length of optical fiber without inconvenience or tangling with the fibers of the other rings. number of rings is chosen appropriately depending on the application.

 Such an embodiment is of particular interest for absorbing variable lengths. Indeed, in the case of connectorized optical cords, it is often desirable to absorb an unknown length in advance of optical fiber. This length varies with end locations. The cassette 9 of the invention makes it possible to choose the ring P suitable for the length of cord to be stored.

 Using FIG. 1, connectors 8 can be placed close to the protective rail 1, for example bilaterally. According to the invention, a bay bottom connector is then connected to the various mechanical distribution and distribution elements by means of a flexible sheath 34 of split protection along its length. Thus, each sheath 34 can protect several fibers simultaneously, for example 20 fibers, and therefore has a sufficient diameter. These sheaths 34 are split longitudinally to allow the insertion or extraction of the fibers without damaging the other fibers contained in the same sheath 34. In addition, the sheath 34 is relatively flexible and rigid simultaneously to avoid any risk of crushing, compression , traction, bending, as well as to avoid weak radii of curvature. They are advantageously made circularly ringed. These sheaths 34 are connected to the rail 1 of the invention by means of a sheath connection similar to that described for the junction box 3.

In the general case, these sheaths 34 can also connect the two rails of FIG. 1 or else route optical channels towards components placed on the plate 7 for example.

 The junction box 3 is mounted like the cassette 2 in excess thickness relative to the rail 1 thanks to a spacer 31 of thickness chosen greater than that of the rail 1.

This spacer 31 also serves as a means of fixing the housing 3 to the rail 1 by means of screws (not shown) fixed in the holes of the central file 10 'of the rail.

 The junction box 3 is essentially formed by several sheath connections 35 making it possible to connect the sheaths 34, for example two, as shown in FIG. 2; these sheath fittings 35 are also split longitudinally according to a slot 350 of width chosen as a function of the diameter of the optical fibers F01, F02 sheathed or not.

Indeed; the slots (340, 350) provided in the sheaths 34 and housing 3 allow rapid extraction of one or more fibers from end to end from the distribution device of the invention. A box 32 supports the two sheath connections 35 and secures them by connecting them to the spacer 31.

 In this way, the distribution device of the invention allows an extraction of one or more fibers without handling the other fibers and this from one end to the other of the distribution device of the invention.

On the rail 1 of the invention, are also placed, as shown in FIGS. 7 and 8, a terminal block module 5 as well as a plate 6 for associated redistribution. In their main function, the terminal blocks 5 ensure the mixing of the optical channels and / or more particularly the interconnection to the optical wiring of all the components with outputs fitted with pigtails. Such components are for example 1 to 2 couplers, special components or the like. The terminal module of the invention is shown in Figure 6 in sectional view along the central column - of Dercaaes 10 'or lateral / 100-du-rail 1. The terminal module 5 is es
substantially formed of a spacer 51 rigidly fixed in excess thickness with respect to the rail 1, on a central file 10 ′ or lateral (10 ", 10 ′) of holes for this rail. The spacer 51 is integral with a plate 57 supporting the different modules used to integrate the components. A T-shaped module 52 is either a specialized terminal adaptation support or is equipped with a standardized rail 54 allowing a plurality of commercially available terminal blocks 53 to be received. , the module 54 receives opposite five terminal blocks 53, or ten terminal blocks per module 54.

de la demanderesse. Des attaches 56 fixant les extrêmités des fibres à la platine 57 assurent le maintien des fibres optiques à proximité des épissures 58.FIG. 8 represents an alternative embodiment of the terminal block support 5 of the invention for which the support plate 57 is mounted on two identical rails (1, 1a) placed at a certain distance from one another, distance chosen from appropriately: The plate 57 is then fixed on an inner lateral file (10, 10 'or 10 ") of holes of each rail 1 or 1 bis. In this way, it is easy to equip the plate 57 with a plurality modules 52 placed at a certain distance from each other These modules 52 can either support the same terminal blocks 53, or, in the example of FIG. 7, receive splices, either removable 58, or fixed 55. In the in the case of fixed splices 55, it is possible either to use the aforementioned module 54 or to use a specialized support, not shown, compatible with the system. These removable splices 58 can be placed vertically in the direction of the rail 1 one beside the other and be for example produced in accordance with the patent

of the plaintiff. Fasteners 56 fixing the ends of the fibers to the plate 57 ensure the maintenance of the optical fibers near the splices 58.

 In addition, the optical fibers F01, F02, FOn ... originating from the terminal blocks 53 are also protected according to the invention by means of two plates (6, 6 ′) for redistribution at their output from the terminal blocks 53, as shown in the figures 7, 8, 9.

 In fact, on either side of the plate 57 and therefore of the terminal blocks 53, there is also extra thickness on the rail 1 a redistribution plate 6 shown in cross-section in FIG. 6. This plate 6 is essentially formed of '' a housing 61 leaned against the rail 1 and fixed by means of a spacer 65 for raising, for example by screwing, either on a line 10 'central drilling of this rail, or on a side file (10', 10 "-) interior depending on the application. This casing 61 is shown in front view in FIG. 9. This casing 61 is provided with two notches 62, for example in the vicinity of its ends placed opposite the rails 1 and 1 bis according to the variant in FIG. 8 (for which the terminal block support plate 57 and therefore the distribution plate 6 are placed between two rails 1 and 1 bis) .But it would also be possible, as for plate 57, that the plate 6 of distribution is mounted on the same rail. The essential function of c ette platinum 6 is to protect the fibers from the different terminal blocks 53 and therefore to be in the vicinity of these terminal blocks 53. Figure 10 is a cross-sectional representation of Figure 9. Over the entire length of the housing 61, extending parallel to the terminal blocks 53, are regularly placed a plurality of supports 63 allowing a hooking or a screwing of the cover 65. This cover 65, represented in section in FIG. 6, has a flared shape in the vicinity of the end of the support 57 so protect all of the optical fibers from each of the terminal blocks 53.

On the other hand, moving away from the terminal blocks 53, the cover 65 is substantially parallel to the frame 61. Between the supports 63 are also regularly arranged a plurality of clips 66 making it possible to hold the fibers FOi, FOjr FOk which must be distributed, to one or the other rail 1 or 1 bis, through notches 62. On the other side of each rail, 1 or 1 bis, symmetrically with respect to module 5, is mounted another module 6 ' redistribution plate to protect in the same way the optical fibers from the upper part of the terminal blocks 53.

 Such terminal block 5 and redistribution plate 6 modules adapt very particularly to an evolution or a reconfiguration of the wiring plan. Indeed, due to faulty connections or changes in the operation of a network, it can be useful to easily and quickly access a terminal module and this with a reduced mechanical footprint.

 The module 5 terminal block support adapts particularly to this modularity which served as the basis for the design of the distribution system of the invention. The terminal block support 5 even makes it possible to envisage the integration of couplers whose pitch is adapted to that of the terminal blocks.

The various mechanical parts rail 1, plates (5, 6), ... cassettes (2.9), ... are advantageously made of stainless steel but would also be possible in any moldable or extrudable material such as plastic or polycarbonate nylon or in an alloy such as
Aluminum, Zamack, etc ...

 A module 7 can also be placed on one or two rails (1; 1a) to integrate other special components such as coupler-diverter (1 to 8), star coupler (8 to 8) and multiplexer-demultiplexer optics for example.

 This module 7 is in the form of a compartment which can receive several drawers extractable from the front, each of them having specific adaptations linked to the mechanical disparity of the components.

 Such a module 7 is also mounted in excess thickness on one of the inner lateral rows (10, 10 ', 10 ") of holes of the rail 1, which facilitates the passage of the optical fibers in the rail 1 behind the module 7 and facilitates the modularity of the distributing device of the invention. In fact, this makes it possible in particular to individually process the input-output of components equipped with pigtails, the coiling of the channels used or on standby and their distribution to the left cable paths ( 1) or straight (1a) by an interface identical to those previously used, a simple flexible sheath identical to the sheath 34 ensuring the continuity of the protection of the optical channels between compartment and cable tray.

 As with rail 1, the various components (2, 3, 5, 6, 7, 9) mounted on rail 1 are provided with covers.

Only the cover 65 of the plate 6 in Figure 7) and the cover 27 of the cassette 2 (Figure 3) are shown and this for the sake of simplicity. But it is obvious that each of the components is provided with a cover fixed for example by means of the holes 100 of the central file 10 '.
