Description

Network terminating unit

Technical field

The present invention relates to the method and apparatus of the cable of a kind of user of being used for place termination external telecommunications network, be specifically related at the optical fiber distribution frame with outside plant that draws under the environment that Fiber to the home (FTTH).

Background technology

Current Public Switched Telephone Network comprises the cable access network of road through various switches, and this cable access network finally is terminated at the wiring side in commerce, industry or consumer user place.These cables are terminated at the network terminating point (NTE) that is positioned at the user place usually.In the past, these cables once were copper twisted pair cables, but shifted the bigger bandwidth that is provided for communicating by letter to the user to FTTH gradually.

The most of users that are connected to access network by optical fiber are commercial entities.Up in the recent period, the sky high cost that obtains the light connection has hindered the participation of individual or dwelling house.In addition, support the high-lighting of current optical-fiber network termination (ONT) equipment (it is unimportant in industrial or commercial setting usually, and it is ensconced in the private communication room usually in these environment) that optical fiber connects not to be well suited for the dwelling house situation.Yet, the demand of FTTH is increased gradually along with price begins to reduce.

Current, in the copper based system, in fact, only after making up the place, just connect the residential customer place to communicate.This process generally includes following steps: will be from the cable that is terminated near the access network the user place from the main crossings tie point that is arranged in street cabinet (street cabinet) by the overhead or underground wall of guiding to the place of presenting.Pass the structure boring of wall, insert with the cable that allows to arrive and enter the residence.Cable enters inside, residence, and is terminated at NTE (for example, in Britain, being NTE5 bus box).As its name suggests, the common mark external web services of NTE supplier's (for example British Telecomm of Britain) the authority and the legal range of responsibility.Terminal block covers the naked access hole on the inwall, perhaps by mounted on surface or be embedded into installation, and comprises the slot that is used for compatible connector plug (for example BT431 connector of phone) on panel.

The box of mounted on surface is often in abutting connection with the about 36mm of wall, and heavy usually and lack aesthetic feeling.They also are subjected to accident or malicious damage easily, because they can be beaten and move.Embedding the box of installing need use with the end box of compatibility.Yet it is more consuming time that these boxes install the specific surface mounting box, because needs are broken metope to generate the suitable cavity of admitting end box.

The existing method that the copper cash tip node therefore is installed is subjected to such puzzlement: to be used to inlet that External cable is entered in order generating, to need by damaging the building structure in place.NTE or not attractive heavy installs thereby be suitable for dwelling house especially, perhaps install by building basic structure is further transformed, and cost is quite high, professional technique requires high, also inconvenient.

The current method that NTE is positioned on the inwall of place produces Reachability question.External web services supplier need arrange to install and be connected with meeting to enter the place of user, perhaps carries out other work relevant with tip node, for example maintenance work, test or replacement.It is individual very important problem that the busy and conflict of the timetable of external service supplier and resident family causes this.The service supplier will seek mainly to carry out during office hours their work, and the user of this time period work will stay out.If timetable can not match (this may be owing to the factor that exceeds outside the range of control in many ways takes place, although arranged concrete time-slot), then lost the plenty of time, and rearranged and the financial cost of visit is quite high again.Also lost valuable business reputation in this process, this is particularly important in liberalized telecommunication market.

A kind of solution is at place outer setting NTE.This is the common practice of the U.S..Though this solution makes external web services supplier can be easy to insert NTE and tip node really, this position of equipment be subjected to easily environment, reach the infringement of malice unexpectedly.The NTE housing must be made very firm in to protect its contents, and this can influence its cost and size.In addition, the housing with equipment is repositioned onto (this is meaningful especially under the situation of dwelling house character) attractive in appearance that the place may not necessarily have been improved in the outside in the place.As what below will describe more comprehensively, fragility, cost and the size of optical-fiber network termination (ONT) all increase, and this may make it not be suitable for this rapid wear position of outside, place.

Also has another problem about the network terminating point accessibility.In Britain and many other countries, the single service provision chamber of commerce provides the phone from the network insertion to the living room over and done with in the epoch of interior everything for the user.The user freely customizes themselves intercommunication needs now.The problem that the service supplier experienced has been discussed; The user should not experience and insert the outside identical problem of NTE that is positioned at, but may produce other problems, safety problem for example, for example the user directly sees the danger of plug end and the laser hazard that is associated (if the user can then may produce these problems near the fiber plant that arrives from access network).

Above problem is main relevant with the copper based system, but has more than relevant with them.Described problem is also relevant with the appearance of FTTH.This is because the fragile characteristic of ONT equipment and optical fiber connect the susceptibility for imbalance, dust etc.(in this manual, " fiber unit " of indication should comprise single optical fiber spare and the fibre bundle that comprises a plurality of optical fiber spares.)

Different with copper cash, optical fiber has intrinsic minimum bending radius, wants fiber unit not to be caused physical hazard or just can not surpass this minimum bending radius to the danger that optical fiber properties has a negative impact.The minimum that only comprises the exposed optical fiber of core, covering and a cushion allows bending radius to be generally 60mm.Comprise that the optical cable of its external protection and fibre bundle have even bigger minimum allows bending radius.Therefore the size of optical fiber housing need be formed and to adapt to bending.

In addition, supporting that light is connected to the equipment (for example device power supply (DPS), Ethernet cable, coaxial cable etc.) in place may be more than supporting that copper cash connects devices needed.This all mean the equipment that is used for FTTH housing overall dimensions will in addition than now copper base NTE bigger (even more ugly and be easy to impaired), no matter be positioned at inside, place or outside.

Another problem that Britain occurs is the promotion of Ofcom (supervision of Britain's communication industry and competition management mechanism) to open access network, has caused more keen competition between the service supplier.Applicant prediction accurately limits the boundary of network terminating point with the limitation of liability of clearly dividing the access network service supplier with needs in this case.Communications Market provides epoch up to the everything that comprises phone away from the access network service supplier.

The ONT of the existing method of termination optical-fiber network is positioned at the ONT identical position used with copper base NTE, promptly is positioned on the inwall in place or the outside, place.Because size increase, the optical fiber of the required housing of ONT equipment and any fitting piece of connection or the fragility of wiring are provided, make the problem worse of NTE experience.

Owing to above reason, wish to have a solution, solve with tip node and be positioned at the problem that inside, place or outside, place are associated access network.

Summary of the invention

According to a first aspect of the invention, a kind of device that is used at the network cable of place, user place termination public communication network is provided, this device comprises the terminating set that is used for the described network cable of termination, and allow the coupling arrangement that between described public communication network and described user place, is connected by described terminating set formation, described terminating set is encapsulated in the outer wall in described user place, described device comprises that also outside first of the described terminating set that inserts can closedly insert the hole from described user place in permission, and allows to insert second of described terminating set can closedly insert the hole in described user place.

Embodiment

Prior art

As above summarize, the current method that provides telecommunications to connect (based on copper cash or based on optical fiber) for the user place is these telecommunications to be connected reconstruct in the buildings.This be by with cable or optical cable pipeline from access network from the top (for example from electric pole (according to overhead structure)) or guide to the place and finish by being embedded in underground cable pipeline (according to underground structure).Generate by the wall in place (or a plurality of wall, under the situation of cavity wall device) is drilled then and insert the hole.In Britain, widely-used cavity wall separates the inside and the outside in place.These cavity walls generally include two parts or shell, can form isolation between them.In cavity wall assembling shown in Figure 1, W1 and W2 are respectively outer wall and inwall.Outer wall W1 has WF1 to the outside, and inwall W2 has to inner face WF2.The cable of introducing from external network (1) passes the one or more accesses hole (2) that for this reason generates.Cable (1) terminates at the network terminating point place then, for example the terminal block of similar NTE5 (4).This terminal block is positioned on the inwall (W2) in place or its.It can be installed on the surface of inwall as shown in the figure, perhaps is embedded into to install to make this box diminish slightly from the outstanding degree of wall.

Fig. 2 represents front view and the rear view of general NTE (4), NTE5.On the plate (6), setting is the inlet (8) of slot form to be used for the compatible connector plug such as the BT431 connector in front.On (10), cable can arrive at by a hole in the end box (it is for mounted on surface or embed installation), and is terminated at the screw thread terminals overleaf.

As mentioned above, by reconstructing this method costliness, waste and the trouble that provides telecommunications to connect to the user place.What obtain lacks aesthetic feeling from the outstanding NTE of user's inwall; The NTE that embeds installation is installed further destroys inwall, and need a large amount of cost, time and professional technique.When the inwall (W2) that is positioned at the user place as NTE is gone up, be responsible for the side coordination that a side of external network must enter inside, place with permission; Either party fails to act agreement and can cause wasting plenty of time and money, and loses prestige.

In addition, current NTE device and installation method only are devoted to lay the copper twin wire, thereby when the place being upgraded to the light connection, operation and damage further expensive consuming time must be stood in the place.This is because the characteristic and the copper cash of optical fiber have essential distinction: for example optical fiber is to the bending height sensitivity.Get around radius bend and too tightly to cause optical loss to increase and can cause optical fiber to damage or even fracture.Yet copper cash is to bend-insensitive, and may under the condition of badly damaged optical fiber the copper twin wire be installed routinely.

First embodiment: single chamber

Fig. 3 shows first embodiment of the invention as the single chamber device with the decomposed form of its ingredient.Device (5) comprises housing (20), fiber management adapter (30) and protecgulum (40).Present embodiment with fiber management adapter will be used for by the distribution cable of (WF1) to the outside that arrives at outer wall and the device of (with the cavity fed with opposite, referring to following for example Fig. 8 and 9) is presented in the outside.

When mounted, this device forms the part of building structure, as " brick substitute ".It is made in proportion, can be installed in the wall thus, and in a single day install, and then preferably substantially can give prominence to from (WF1) to the outside of wall or to inner face (WF2).

Preferably, this device is installed when construction of buildings.If wall is made of the room brick, then this device can be placed in the mortar and also this device be installed like the room brick just as it.Do like this and can realize a remarkable advantage of the present invention, will avoid in the future by reconstructing expense and the labour who destroys building structure because when building, install.Yet, realize adopting other advantages provided by the invention also to fall within the scope of the invention by the reconstruction erecting device.

According to the preference pattern of above installation, housing or socket (20) provide the parts that are used for incorporating into wall to building industry when building the place.This unit is made with the material (for example, steel or engineering level plastic material) that is used as " brick substitute " when mounted by enough firm.For the highly basic that exists in most of building mortars, this material is should be preferably inresponsive or be subjected to enough protections to it.In addition,, then should not lose its desirable mechanical property under the influence of its ultraviolet radiation that in daylight, exists, this means and use insensitive material or give of the suitably also lasting protection of this material ultraviolet radiation if use plastic material.And, in order to improve combining of mortar and housing, preferably will be with the surface of the brick of mortar combination to coat with lacquer with the coating of mortar.This can for example be fixed on the surface of shell by assembling (for example, sand or coarse sand) gummed or other modes.

In the embodiment shown in fig. 3, housing (20) comprises volume and associated components (for example brick) the essentially identical room (void) that constitutes wall.This device comprise be used for admitting bond pad (23) (coming it is discussed) for example below in conjunction with Fig. 6 hold arm (22).Any other parts that in described room, also can ccontainingly be used for the termination, connection etc. of cable.Especially, this device can be used for various cable type (copper twisted pair cable, coaxial cable, optical fiber etc.), and therefore applying flexible of the present invention also can be upgraded to optical fiber from for example copper twin wire, because it can handle both characteristics on an equal basis well.Therefore the present invention helps the user place of facing the future in this respect.

In Britain, the long usually 215mm of the building brick of standard, wide 102.5mm and high 50 or 65mm use with the mortar joint of 10mm.Sometimes use other sizes in Britain, the standard size of other countries may be different with the standard size of Britain.Obviously, accurate dimension according to housing of the present invention can be set at the standard brick size of locality.Equally, if local building " brick " is the stone or the cement block of certain other Commonly Used Size, then this size can be used as the basis of setting shell dimension.Yet it may be useful and actual being of a size of the housing that about 175mm to 250mm is long, 75mm to 150mm is wide and 50mm to 150mm is high, not big simultaneously to bringing structure problem to wall construction.Generally speaking, should avoid housing excessive.

Adopt the present invention in order to encourage and to be convenient to building industry, guaranteeing to need not the bricklayer just as any other brick or building block are placed by housing of the present invention, to adopt his or her operation technical ability be wise.This hints that this housing should be not longer slightly, wideer or thicker than standard brick, also should be not thin excessively.Certainly, people can find to use " Double Length " or " double height size " housing (but the actual loss of considering a mortar joint of its size).What be easier in many cases use is the housing of half length, because many brick patterns (combination) use bat.Yet the parts of all expectations and optical fiber can not always be fit to bat.In addition, for this bat, the bending of optical fiber management may be a problem (depending on fiber type).Described housing can also slightly be narrower than conventional brick, even if but have superiority in this respect, advantage is also very little, and in fact full duration also is useful for housing engagement members and electron device.

Prior art NTE box such as NTE5 is mainly used in a purpose, and promptly termination is from the cable of external network and be provided for holding slot such as the connector plug of RJ11.Because the position that this box is installed, its deviser is intended to its size is remained minimum to reduce it from outstanding (the mounted on surface) of wall or make it easy to install (installing embedding).

Relative with it, the present invention's device in a preferred embodiment comprises relatively large room, and is promptly similar substantially with the volume of relevant building component (for example room brick).In a preferred embodiment, in the room, not only be useful on the space of the cable termination and the device of the traditional NTE function that is connected, but also be useful on space such as other functions of fibre optic memory, passive optical equipment, DSL filtrator etc.By having the volume that comprises other functions by this way, adopt device of the present invention will reduce the amount of the telecommunication apparatus that resident family can see in the place.Because being used for of research and development recently still remains the equipment and the device of the method researched and developed and technology and may drop in the equipment of the present invention, is of some use so can also scrap too early prevent mean.

Distribution cable/optical fiber pipeline from external network can enter housing (20) in many ways from the External cable pipeline, and these modes for example have:

The pipeline at the ground level place by terminating at the outside surface (WF1) against outer wall carries out underground presenting, and upwards crosses wall then to equipment, and enters via the front portion of fiber management adapter (30);

The pipeline of locating by the outside surface (WF1) that terminates at against outer wall carries out overhead presenting, and crosses wall then downwards to equipment, and enters via the front portion of fiber management adapter (30);

In having the device of cavity wall, carry out underground presenting, in presenting, cavity upwards passes cavity then towards the equipment rear.

In this manual, " cable " of indication suitably will comprise the blown optical fibre pipe under the situation, and wherein the user place will be at first by the blowing installation pipeline before optical fiber is installed.

Cavity is presented the situation that most probable is used for " newly-built ".The advantage that by this way cable is supplied to the place is that the protection cable is not subjected to the influence of the physical environment on pipe outlet.In cavity was presented, the cable of external network was delivered in the housing via entrance (25).

Preferably, be set a plurality of portalling can select the location of entrance in housing.This can allow housing to be arranged on to prevent any strain that pipeline location produces or the optimal location that makes this strain minimum.Terminating in the overhead or underground feed conduit at the ground level place of outer wall, entrance can be positioned to make as much as possible the cable of introducing to keep vertical.

Accompanying drawing shows flange (26) and backboard (28), and they can be arranged on the outside, so that when housing is installed, it is correctly aimed at and locate, and support afterwards and stationary housing.

Embodiment shown in Figure 3 comprises fiber management adapter (30).This is used for optical fiber installs, and wherein light pipe road or optical fiber arrive at (with the cavity fed with opposite) via outer wall.Path (32) is set to hold light pipe road or optical fiber, and this path is constructed to around bight (for example, 34) guiding pipeline or optical fiber.The optical fiber property decline that this has controlled fibre-optical bending and can help to prevent overbend and cause.Preferably, portal (for example, 25) are set to admit pipeline or cable in the fiber management adapter from a plurality of entry positions.

Equipment shown in Figure 3 comprises protecgulum (40).Equipment of the present invention is configured to be installed into make can be from the outside, place near housing.The contents of this lid protection housing (20), otherwise these contents will be exposed to physical environment.The seal stand wind and rain preferably is set is sealed in junction surface between lid and the housing body, for example to prevent into water.The locking mechanism of certain form can also be set, although lock may be set when mounted: lock at the supply circuit fashionable dress in the future.

In a preferred embodiment, make the color of the outward appearance of protecgulum, quality etc. similar to the miscellaneous part that constitutes outer wall (common room brick, breeze block, stone or cement block etc.).Thereby the existence of this device will only influence to minimum degree the outward appearance of (WF1) to the outside of outer wall when mounted.

Fig. 4 is the exploded view of the ingredient of this device when being used for the cavity wall installation, and wherein cable pipeline enters housing (20) by underground presenting.In the cavity of housing, include gas block connector (21) (it is used for any gas that barrier system exists when using the blown optical fibre pipe and exceeds this point).Alternatively, the present invention can make gaseous emission to the outside, place, and seals the path that imports inside, place.

Fig. 5 A represents to be equipped with on it housing (20) of fiber management adapter (30).Be recessed at that to hold in the arm (22) be another optional thing, i.e. parts dish (23).This dish is contained in slidably to be held on the arm (22), and promotes and it is installed to the housing rear by this rim arm.In the drawings, this dish is pulled out to illustrate it better from its make-position.This dish can otherwise be installed in the housing certainly, for example on the pivot of level or Z-axis, and slidably the perhaps combination of these field engineerings is installed.In the present embodiment, this dish is to hold the light pipe road that enters this equipment or the optical fiber memory disc of optical fiber, and himself path is used for control and guiding fiber or pipeline bending.This dish can comprise or ccontaining passive optical equipment or miscellaneous part equally.In the present embodiment, exist the space further to hold the sealed electrical submodule by follow-up dish or other forms above the parts dish, for example NTE, DSL filtrator, printed circuit board (PCB) or other parts (27) etc. are shown in Fig. 5 B.

Fig. 6 is illustrated in and is arranged in the equipment that holds the overhead and underground structure of presenting on the outer wall when being installed on the user place.(accompanying drawing mainly shows two feed direction for the illustration purpose, though usually only a feed direction be used for any installation.) removed protecgulum (40) so that the contents of housing to be shown.Here, the housing (20) that is equipped with fiber management adapter (30) on it comprises optical fiber memory disc (23).In optical fiber was installed, the fiber management adapter provided the guiding of the bending of the optical fiber of access arrangement and control, thereby protection optical fiber can not crookedly not get tension.

The figure shows in fact owing to have mortar and fuzzy feature between the brick layer.External cable (1) guiding is crossed the outside (WF1) of wall and by (25) access arrangement that portals.Along path (32,34) the guiding cable of fiber management adapter (20), remaining optical fiber is stored on the optical fiber memory disc (23) (illustrating with closed position here) in it is fed into gas block connector (21) before then.

Fig. 7 A and 7B are illustrated in the route of interior light pipe road of the equipment of constructing as shown in Figure 6 or optical fiber process.Two width of cloth figure represent that pipeline terminates at that blown optical fibre pipe on bond pad one side is installed and pipeline terminates at blown optical fibre pipe installation on the bond pad opposite side.Can the lead NTE of the equipment that is positioned at of this pipeline.External cable is sent to bond pad, this bond pad place External cable with from the fiber splices that may be connected to NTE of inside, place.Alternatively, External cable can engage with the optical fiber afterbody of drawing from the NTE module that is positioned at present device.

Fig. 7 A represents to cross the underground of wall surface and presents, and presents and Fig. 7 B represents that wall surface is overhead.

Fig. 8 represents not have this equipment of its protecgulum, and it is equipped with the cavity channel feed structure, has gas block connector (21).Here the External cable that illustrates (1) is presented guiding to be sent in the gas block connector by underground.This structure lacks fiber management adapter (30), because it only manages the introducing optical fiber that arrives on the outer wall surface.

Fig. 9 is illustrated in the outer wall (W1) that cavity wall is looked in the cavity of separately W1 and W2 in installing, and shows the rear view of the embodiment of the invention.The backboard (28) of the housing (20) in the time of can seeing in being installed on outer wall (W1) from this view, wherein External cable (1) is by the underground housing that enters in the wall chamber of presenting.It also shows backboard and be and how to help after installation this device support and remain on the appropriate location.Internal cable pipeline (4) points to inwall (W2, not shown) from outer wall, thereby Internal cable is introduced the user place by inwall, provides to be used for the device that telecommunications connects.

Figure 10 A and 10B are illustrated in the outer wall in the user place that comprises present device (5) in the cavity wall installation and the cross section of inwall.In Figure 10 A and 10B, equipment is shown as by the underground cables pipeline and is fed.External cable (1) arrives at the bottom of outer wall surface, and upwards advances and access to plant.

In equipment, carry out crooked management (if cable comprises pipeline/optical fiber) and termination (can not occur in the inwall W2 or under the situation on it) afterwards at this, cable from the outer wall road through cavity, the further road of cable is through crooked management equipment (31) in Figure 10 A, and this bending management equipment is the bending radius of may command optical fiber cable in due course.Crooked management equipment among this figure is represented as the type form that is the hollow plug that is positioned at the wall main body.Use this equipment will help to reduce to enter the cable in place in the projection degree on inner face (WF2).Should be clear, can use the alternative bending control device to replace the slotting embodiment of fastening shown in Figure 10 A.For example, can on the surface of inwall, use the bending of fibre-optical bending control---internal part (11) can comprise the device that is used for this purpose.Alternatively in copper cash was installed, parts (11) can comprise the copper cash outlet.

Bending on inwall control is expectation of the present invention but inessential feature.Cable can only pass and insert hole (2) to be exposed to inside, place.Therefore Figure 10 B is illustrated in the interior installation without any bending control device of inwall.

The description that utilizes underground configuration of presenting with similar to overhead description of presenting, just arrived on the surface of outer wall and is positioned at the height place of equipment top at cable (1) under one situation of back.

As above together with Fig. 3 described, equipment of the present invention can comprise a large amount of devices and problem that the equipment amount increase that do not have the thing followed and user to see is associated in structure.By using this equipment, can significantly reduce the telecommunications foreign material of inside, user place.

Figure 11 A and 11A be respectively with Figure 10 A and the outer wall in the similar user of 10B place and the cross section of inwall, but be to present in the installation at cavity.The underground pipeline of External cable (1) in the wall chamber sent into the rear of the device (5) that is installed on the outer wall (W1), and External cable is terminated at the there.The Internal cable road is come to connect for the place provides telecommunications through inwall (W2) then.

With Figure 10 category-A seemingly, in Figure 11 A, can see the crooked opertaing device (31) that is the plug form that is positioned at wall construction that will adopt.Figure 11 B is illustrated in the wall and makes cable only pass the similar installation that inserts hole (2) without any crooked opertaing device.Yet simple crooked control can realize in the surface of inwall (WF2).

The termination of external network occurs in the equipment of the present invention that is arranged in outer wall: this has realized the whole benefits of the present invention aspect the saving space, because use by this way this equipment mean go up to inner face (WF2) required whole are the interfaces that are used for user's telecommunication apparatus, for example be used for slot such as the connector of RJ11 plug.Therefore, by using this equipment to remove otherwise must be contained in the ugly and flimsy foreign material of inside, place.

Second embodiment: two chambers

The above first embodiment of the present invention has been described the single chamber housing (20) that places in the outer wall (W1).In the preferred embodiment of the present invention, this equipment comprises two parts or the chamber of the full duration of extending wall.This equipment is mainly used in the relatively large wall of width and installs, cavity wall for example, and allowing the user to be easy near particularly favourable aspect the tip node.

Figure 12 represents two chambers equipment from " outside " visual angle, the service supplier may adopt this equipment when being installed in this equipment in user's wall.This equipment comprises the housing with first Room (100a) and second Room (100b).First Room or mistress (100a) be towards the outside in place, and be intended to and can entered and be responsible for by the service supplier.Second Room or user chamber (100b) are intended to and can be entered by the user.In the present embodiment, two chambers are separated by partition wall (101).

In the present embodiment, two chambers are nested each other, and shown in arrow (102), but the technician will appreciate that this is a kind of mode that two chambers are fitted to each other.Equally, be appreciated that layout, can carry out many changes with being connected about the shape of housing and chamber according to wall.

During installation, these chambers are drawn back each other, make can enter these chambers at the wall surface place inside and outside towards the place when mounted.Preferably, these chambers are installed during building the place.

The external access network cable (104) that illustrates is presented according to outer wall surface inlet and is entered housing, but the cable of other patterns is presented certainly and also is fine.For example, cavity channel (105) can hold the cable that the cavity by between the walls enters.Mistress (100a) comprises optic fibre connector or bond pad (106) and optical interface or connector (108).Here the bond pad that illustrates is built in the hinged door (105) of chamber, but it also can adopt above-mentioned form about single chamber equipment.The External cable that enters (104) engages at the bond pad place.Therefrom, another fiber unit (110) is connected with the light terminator (109) that inserts optical connector.Even the user also must be connected to ONT with his cable, thereby but the place also is ready to admit user's cable that his equipment (for example, his modulator-demodular unit etc.) is connected to external network, and on this meaning, this has been connected to external network with the place.

The optical connector of the optical fiber of external network normally double flute is admitted light terminator (109), and it carries the optical fiber from access network on a side, and carrying is from the optical fiber of subscriber equipment on opposite side.If user's cable comprises optical fiber, then can be equipped with similar terminator.In the drawings, the optical connector that illustrates is positioned on the partition wall (101), makes each slot outside and inner towards the place.

To alternatively above-mentioned, the fiber unit that enters of external network need not at first to engage at the bond pad place, but can be by engaging or utilizing the light terminator to be directly connected to optical connector.

In installation shown in Figure 12, optical connector is used as the ONT of segmentation service supplier responsibility boundary: exceeding optical connector is exactly user's space.Optical connector or other this unit clearly define border in many ways like this.The existence of partition wall (101) is not subjected to entering of its other party to strengthen this point by each chamber of other protection.Yet the next door is not essential to the invention.And separation does not need to be positioned at any ad-hoc location of housing, though this optical connector advantageously shown in this Fig is positioned on the partition wall.

When the optical fiber (110) of termination is connected on the optical connector, think that the place has been connected to external network.Multiple access point (111) can be set in the user chamber, multimedia and Network Access Point as the place, thereby the cable (113) that the user can be connected, for example be used for that data (for example Ethernet), video are coaxial, the cable of phone and other networked devices (for example, WLAN and DECT phone).Here can also comprise the power cable that is used for ONT.The technician will understand, the equipment that can comprise various other types for example allows the basic standby power supply (for example, allow calling 911 phone) of urgency communication when power fail, replace electric supply solar panel, satisfy the optics trikle charger of ONT electricity needs, or the like.

To the above-mentioned third-party test that carries out to confirm integrality from the light path of switch or other device ends;

Service supplier slip-stick artist inspects to form with " copper cash " of ONT equipment (power supply/warning horn, Ethernet, voice to possible video coaxial cable) and is connected, and leading subscriber place equipment is constructed;

Possibly: inspect the installation/third-party test that breaks down with diagnosis again by service supplier slip-stick artist;

Possibly:, then inspect again by service supplier slip-stick artist if the result in said process wants place under repair/replacement.

For the single chamber form, WF1 is the wall towards the outside, place, and WF2 is towards the inside in place.Mistress (100a) is communicated with user chamber (100b).External cable (104) can pass wall surface (104a) or present (104b) by cavity and arrive at from access network via cavity channel (105).To insert optical connector (108) from the fiber unit (110) that enters cable and be equipped with light terminator (109), this connector is placed on the partition wall (101), and its slot is towards both direction.

This equipment drawing has represented how housing crosses over the whole width of cavity wall, thereby allows service supplier and user to enter the optical connector of representing ONT and responsibility boundary line.As mentioned above, this boundary line does not need to be arranged in any specific part of the housing of wall space, but because actual cause, is located near the central spot of wall width or central point to allow the easness that enters of each side to be roughly the same.As can also be seen from Figure, the service supplier can enter ONT from the access point from the outside, place on (WF1), and does not need to obtain to carry out inner place.The user is also by arriving the user chamber and enter ONT easily from inside, place at the access point place that is positioned on (WF2) simultaneously.

Said apparatus and method have been described the specific concrete enforcement of inventive concepts, the termination that notion of the present invention is not limited to telecommunications cable be connected, but can expand to any situation that needs cable to enter the place.In most preferred embodiment, need not to change building structure with erecting equipment, after the demand to service finishes, need not to remove this equipment, if but wish and it can be stayed in the building structure of wall.

Use is according to a remarkable advantage of device of the present invention and installation method, and external web services supplier now can the upstream end contact, and needn't arrange inside, calling party place.As above sketched, the difficulty of arrangement of time is the realistic problem that can measure aspect money by considering lost time, manpower and prestige.Therefore adopt the present invention to help to solve and the initial cable in user place is connected to the problem that external network is associated.In addition, can also obtain at any time to enter the relevant real advantage of ability that NTE or ONT for example test connection with external web services supplier.

Another significant advantage that the present invention surmounts current apparatus and method is that it is of some use to the installation towards future.The ability of equipment makes it can hold relatively more and the telecommunication apparatus of extensive farming class more, thereby in case housing has been installed, just can comprise suitable parts in housing (20).Its position on outer wall makes the personnel from external web services supplier can safeguard and test NTE, but also can for example remove and/or add the parts current place that the copper cash phone connects that has of upgrading, so that optical fiber is directly introduced in the family.More than describe fully with reference to this example that the place is upgraded to optical fiber from copper cash; Same copper cash is scalable to be coaxial cable or other cables, perhaps under the less situation of possibility, light connection or coaxial connection is downgraded to the copper cash connection.

For simplicity, mainly under to the cavity wall installation environment, the present invention has been described here.Obviously, the present invention also can be used for solid walls building (that is the building that, does not have cavity).Now, in non-tropical climate, this wall is thicker relatively usually at least, and thickness is the twice of brick width at least under situation about being made by brick.Therefore in this case, will adopt the single chamber housing to replace brick to be used in the skin of wall, suitable hole is set in internal layer to allow inserting interior of building from housing.Equally, if single chamber equipment is expanded insufficiently for this reason, the full duration that then can adopt of the present invention pair of chamber form to install with the expansion wall.
