Description

SECONDARY NETWORK CONNECTION HOUSING FOR AN OPTICAL NETWORK CONNECTION

The invention relates to a network termination housing for an optical network termination according to the preamble of claim 1.

A housing for such a network termination has become known, for example, from EP 1 626 300 Bl. According to this prior publication, the described optical network unit is intended and suitable, above all, for use in the premises of end consumers. In this respect, it is often spoken of FTTH networks, so-called "fiber to the home" networks. The term "home" also stands for other buildings or squares, for example also for offices etc. Such units are thus also suitable and usable for commercial spaces in many respects.

As broadband connections become available, cable networks are being increasingly expanded. This raises the question of how these cable networks connected to a corresponding optical network termination and then the various user modules to be provided and fed to it, which are needed for a variety of services. As is known, computers, ie PCs, notebooks, etc., can also be connected via these modules, frequently including network terminations similar to rooters having a plurality of LAN connections, frequently referred to as Ethernet connection sockets. Likewise, USB connections, coaxial plug connections, for example for the connection of televisions and radios (so-called CATV connections), telephone connections, etc., may be provided. Usually, a plug-in connection for an external power supply for the power supply is also provided, wherein not only, as in the case of the computer network connections, the connections for the other services can also be provided several times as required.

In accordance with the aforementioned prior art, a housing for an optical network unit is proposed, which has two separate chamber devices. One of the two chamber devices serves to receive and accommodate the ends of the incoming optical waveguide fibers, which can be accommodated, for example, in one or more loops lying more or less in one plane in this chamber device. It is proposed that the one or more optical waveguides or optical fibers are provided with a terminator and inserted in an intermediate wall of the two-chamber device system. The chamber device, which is separate from the first chamber device, ultimately serves to accommodate one or more user modules, via which the corresponding data provided via glass fibers are processed and be provided for the different devices to be connected. These modules are then connected to the above-mentioned, accessible from the outside of the housing plug-in connections. According to the generic state of the art, the two chamber devices are parallel to the base or top of the housing side by side, wherein the first chamber means can be closed by a first lid and the second chamber means by a separate second lid.

A coaxial connection device, in particular for a house transfer point with a corresponding interface has become known, for example, from DE 37 23 960 C1, which in addition to a cable connection unit includes a connectable to an interface complete device, which according to the needs of consumers with active and / or passive the Signal on processing and processing circuits may be provided.

A housing arrangement comparable in principle can also be taken from US 2005/0145522 A1 as known.

A cable connection box for optical waveguides to be mounted on a house wall or the like is also described in DE 42 18 378 A1. The housing includes a removable lid. In order to enable a subsequent additional insertion of optical waveguides with a correspondingly larger space requirement of the optical waveguide, it is provided that at least one frame-shaped element is arranged to increase the housing side surface detachably on the housing.

A generic network termination housing is from the EP 1 835 319 Al became known. It comprises at least two chambers, namely a chamber for receiving one or more optical fibers and at least one further chamber for receiving one or more user modules for one or more services. Furthermore, several connections are provided on the outside of the housing, about which various cables for providing various services can be connected.

The aforementioned fiber box is closed or closed by means of a fiber box lid, wherein under the fiber box a Netzabschlussbox is provided, in which the user modules are housed. The fiber box can be placed on the net box and anchored.

Via an opening in the fiber box, the at least one fiber end located there can be brought out and connected to a connection in the region of the attached end box.

An extent at least partially similar basic design or a similar basic structure of a network termination housing is also the US 5,668,911 A removable.

Based on this last mentioned prior art, it is an object of the present invention to provide a contrast improved network termination housing for an optical network termination, which takes into account different circumstances.

The object is achieved according to the features specified in claim 1. Advantageous embodiments of the invention are set forth in the subclaims. give .

The present invention provides a very flexible housing arrangement for optical network terminations, which takes into account the different state of completion and the different customer requirements.

The solution according to the invention is based on the fact that the entire network termination housing for an optical network termination is constructed similar to the prior art with at least two chamber devices or two compartments, but which are completely separate from one another.

This opens up the possibility that a basic installation can be realized in a base housing, which is also referred to below as a fiber box. In this fiber box, the one or more optical fibers, fiber cables, etc. introduced and kept usually in sufficient length. For this purpose, the fiber cables, as usual, can be laid and provided in one or more loops, generally more or less parallel to one another, inside the box. The ends of the fibers are preferably already provided with corresponding connection plugs on site, which can be positioned in provisioning receptacles provided for this purpose.

Furthermore, the network termination box according to the invention comprises a connection recess, below which an access opening in the fiber box is accessible when the net box is attached to the fiber box. This opens up the possibility that via the access opening the at least one fiber end located there leads out and at a can be connected in the area of the attached network termination box.

Preferably, the aforementioned access opening is provided in the fiber box in the fax box lid, with which the fiber box is closed or closed by itself. This preferably also protected by means of a seal against unauthorized opening access opening can then be opened before placing the network termination box, in particular in front of a person authorized to do so, then with the access opening open in the fiber box the aforementioned fiber end leading out and at a port in the area attached network termination box is connectable.

This base or fiber box can be tightly closed with a separate lid and even sealed if necessary to prevent unauthorized access without breaking the seal to these glass fibers.

In a preferred embodiment, the chamber device provided in the fiber box is divided into at least two separate chambers, namely a first chamber which serves as a glass fiber receiving chamber for receiving and buffering fiber excess lengths and a second chamber preferably connected via a cable channel, in which the glass fiber ends can be stored with the prepared there connectors or connectors for later further wiring.

Separated therefrom according to the invention further provided the actual network termination housing device, which preferably can be placed on the top, ie on the cover of the base or fiber box and anchored there. By opening a preferably sealed access door, the optical fibers and fibers prepared in the fiber box and possibly provided with plug connections can be inserted into the actual mounting box and connected to the prepared internal plug connections depending on the customer's wishes, ie depending on the desired services. This box is then equipped with appropriate modules needed for the services a customer desires.

This structure according to the invention opens up the possibility of first preparing the glass fiber connection in a house and optionally sealing it. At the same time or at a later time then the actual assembly of the optical network termination can be made, according to the customer's wishes with the services that are important to him.

Thus, the optical network termination according to the invention thus represents a key component in the field of FTTH networks. Because the assembly can be done directly in a house or in the apartment of a subscriber, the individual subscriber thereby the entire bandwidth of a single fiber is available. The Modular Phase Management Box makes it possible to initially install only the fiber management box and later retrofit the actual network termination without any construction measures.

Not only can the fiber box be separately prepared, sealed and even sealed to prevent inadvertent external intervention. Furthermore, it is also possible that the network termination module, the following Partially also referred to as Netzabschluss box is placed after the final wiring on the fiber box and closed by a lid so that without destroying the housing opening the lid and access to the underlying cable is not possible. Alternatively, it is also possible to provide a non-destructive but possibly difficult way to open this end cover, in which, for example, the end cap can be levered open with a screwdriver and released from the anchorage. In addition, however, a seal can be applied to the housing in such a way as to virtually indicate a "seal" between the cover and the housing.

The mentioned end cover not only prevents the intervention in the Verschaltungsraum, but also locks the Netzabschluss box, i. The network termination module with the fiber box and thus prevents the separation of the two units from each other.

As low also proves that the housing unit according to the invention for the optical network termination but can also be used as a stand-alone unit, so does not necessarily have to be mounted on the fiber box. If the housing for the optical network termination is not to be mounted on a wall but, for example, set up or stored horizontally, rubber feet could, if appropriate, also be clipped to suitably prepared locations on the underside of the housing or be generally fastened.

The invention will be explained in more detail with reference to drawings. In detail: Figure Ia is a plan view, a Längssei- and until Ic: an end view of the total housing according to the invention of an optical network termination;

FIG. 1a shows, in a schematic plan view, an overall housing 1 for an optical network termination, which is referred to below as a network termination housing or in short also as "ONTU". FIG. 1 b shows a longitudinal side view with the various connections for the various services, and FIG. 1 c shows an end view of the entire network termination housing 1.

This overall housing 1 has a multi-part construction and comprises as a mounting base a so-called fiber box 3 with a first chamber device 103 and a network termination box 5 based thereon with one or at least one integrated internal chamber device 105, which is also referred to below as a second chamber device ,

When mounting the device according to the invention with the network termination housing 1, the above-mentioned fiber box 3 is first in a building, for example, in a week or in a house of an end user, mounted. The fiber box can be mounted by means of screws and dowels, for example, on a wall surface by the fiber box 3 created with its bottom bottom 9 on a wall surface and screwed through holes prepared accordingly holes 11 in the wall or in the wall anchored dowels. Preferably, openings 13 or at least prepared openings 13 'are provided on all four sides and / or in the bottom, ie the rear wall of the fiber box 3, which can be formed, for example, by easy breaking out of wall parts, so that one or more fiber cables or light Waveguide (LWL) 17 can be easily guided into the interior of the fiber box 3, so in the chamber device 103.

FIG. 2 shows a plan view of the opened fiber box 3 and thus of the interior of the chamber device 103, FIG. 2 a showing a corresponding illustration of FIG. 2, but with glass fiber cables laid in the chamber device 103.

From this embodiment it can be seen that two spaced apart in the longitudinal direction of the fiber box 3 cylinder-like elevations 19 are provided, each having an opening 18 in the interior. This opening 18 can for example also be placed on a flush-mounted box. This allows fiber entry through the bottom of the fiber box. In other words, this is thus made possible by the fact that the inner space 103 of the fiber box 3 opens towards the rear side 9. This cylindrical wall rises from the bottom inside 9 ^{1 of} the fiber box 3 over a certain height, being provided on the cylindrical outer side of these cylindrical elevations 19 each circumferentially offset and opposite the bottom inside 9 ¹ spaced retaining fingers 19 '. Around these cylindrical projections 19, the fiber cables, ie the fiber optic cables, which are also sometimes referred to as optical waveguides, or individual fiber strands for buffering and accommodating Glaserfaserüberlängen a or rewound several times to provide sufficient cable lengths in the fiber box. Furthermore, in the case shown, three fiber splice trays 21 or, for example, so-called coupler tubes 23 and at least one passive optical retainer 25 are provided in order to facilitate and accomplish the handling and preparation of the fiber cables and the individual fibers.

Further, inside the fiber box 3 there are provided a plurality of further fiber cable holders 27, below which the fiber cables are pushed in or e.g. can be clipped, wherein the fiber cable holder 27 may be rigid or movable. There are no restrictions in this respect.

The corresponding fiber cables are preferably already prepared in such a way that they are provided with the appropriate connectors in accordance with the services provided for this purpose and the nut-side modules which are ultimately to be connected thereto.

For this purpose, a plurality of shelves 29 for plug connectors are provided in the interior of the chamber device 103 of the fiber box 3, for example shelves for 2 × SC APC connector or, for example, a shelf for an LC twin glass fiber connector etc.

FIG. 2 a shows a similar illustration to FIG. 2, but with a schematic representation of a few optical waveguide ends with the plug-in connectors prepared in advance there. In these shelves 29, the already pre-anchored at the end of the glass fibers plug 30 are stored freely ending. The tray is designed so that the plug with dust caps 29 'can be stored. The respective dust cap 29 remains after removing the plug in the holder and is available for eventual return storage later again.

It can also be seen from FIG. 2 that the chamber device 103 inside the fiber box 3 is subdivided into at least two chambers, namely a first chamber 103 'for receiving the mentioned excess lengths and for buffering the glass fiber excess lengths, and into a further smaller sized so-called Storage compartment 103 ".

It can also be seen from FIG. 2 that the abutment 29 for the plug connectors is located in the aforementioned storage chamber 103 ", which is delimited by peripheral boundary walls 26, which preferably rise vertically from the bottom inside of the fiber box, and an optical waveguide supply channel 24, in which longitudinally spaced and oppositely projecting clamping projections 24a are provided, via which path the optical fibers or splices under the clamping projections 24a can be fed into the interior of the chamber 103 "and the connectors in the said shelves are prepared Positions are stored.

After fiberglass installation, the fiber box 3 is then closed by means of a fiber box lid 31 shown in FIG. In this case, the fiber box 3 and the lid 31 can additionally be protected against unauthorized opening by means of a seal 32, the seal 28 being affixed, for example, to the lid arrangement shown in plan view in FIG. may be brought that only after removal of the seal, an underlying opening clip 33 can be actuated to open after opening the other clips 33 'the fiber box lid 31 and remove, thereby making the chamber means 103 accessible. In addition to the mentioned opening clips 33 and 33 ', the fiber box lid 31 is also held and secured by the inwardly projecting tongues 33 ".

The described fiber box 3 thus serves as Abläge chamber device for various optical connectors and is therefore suitable for receiving any fiber optic cable systems. The cable entry from all mounting directions is possible. The fiber box 3 is particularly suitable for receiving internal splices, couplers or other passive elements. Finally, the described fiber box can also be referred to as an access-protected fiber box, in particular if it is closed by the mentioned fiber box lid 31 and sealed, for example. With attached fiber box cover 31 also the cylindrical projections 19 are covered by the fiber box lid 31 and completely or approximately closed, at least so covered that possibly from a flush box through the opening 18, the fiber optic cable into the glass fiber chamber 103 'are led into it can.

In Figure 3, the corresponding fiber box lid 31 closing the fiber box can be seen in plan view, with the access door 34 closed and sealed, and with the access door opened in Figure 3a.

The access flap 34 is connected via a film hinge 34 'with the rest of the fiber box lid 31 and can through Separation of two lateral webs 34 ", via which the access flap 34 is connected to the section of the fiber box lid 31 located to the right and left of the access flap, are opened by a fitter a tilting or pivoting axis 134 'is formed) and clipped with its clip means 34a in the counter-latching 34b and thereby fixed in the open state on the remaining portion of the fiber box lid 31.

In this case, a smaller portion of the space underneath in the chamber means 103 of the fiber box 3 is accessible, namely that part of the chamber means 103, in which the appropriately prepared and preferably already provided with terminators 30 optical fibers and fibers are stored. This part of the chamber device 103 represents the mentioned storage chamber 103 ", which is accessible via the access opening 134 thus formed.

Depending on the customer's requirements, different modules can now be installed on this fiberbox platform. Due to the sandwich construction, in which the now described Netzabschlussbox mounted on the fiber box and anchored, also results in a reduction of the total required footprint, since only the overall height of the entire housing assembly increases slightly.

In the following further discussion of the overall structure of the network termination, reference is made to the two exploded drawings according to FIGS. 4 and 5, which show the overall housing once from above (FIG. 4) and once more from below (Figure 5) play.

To get to the optical connector in the fiber box 3, so, as mentioned, the access door 34 must be opened in the lid 31 of the fiber box 3, for which purpose the two webs (seal) are severed. FIG. 3a shows the top view of the fiber box 3 closed by the cover 31 when the access flap 34 is open, from which it can be seen that in this position the plug connectors 30 located underneath and located in the storage spaces can be seen at the end of the optical waveguide 17.

When the access flap 34 is opened, it can also be seen that the access opening 134 formed above corresponds in size approximately to the underlying storage chamber 103 "in the fiber box 3, which is delimited by the mentioned circumferential walls 26 to the remaining chamber interior 103 '. so that you can not get into the remaining chamber interior 103 with open access flap 34.

As can be seen from the top view of the open chamber device 103 of the fiber box 3, each adjacent to the left side wall Ia as well as the right side wall Ib at a distance guide pins 35 are provided which are higher in side view than the fiber box 103, that are higher than that the Faxerbox circumferentially limiting side walls 3 '. In other words, the guide pins 35 project beyond the fiber-box lid 31, the guide pins 35 protruding upward through corresponding openings 31a in the fiber-box lid 31. These guide pins 35 can now be used to put the network termination housing 5 thereon and to anchor. The contour can be the fiber box 3 can be used as a guide.

In FIG. 3 a, as mentioned, similar to FIG. 3, a top view of the closure lid for closing the fiber box 3 is shown, but with the access flap 34 opened. In FIG. 3 b, the net closure box 5 is also shown (with the closure lid not yet finally attached), wherein the Netzabschlussbox 5 is placed here on the underlying Faserbox 3. In this case, the network termination box 5 has a connection recess 41 which, when the network termination box 5 is positioned in a positionally correct manner, is positioned on the fiber box 3 above the opened access flap 34, so that through this recess 41, the underneath in the fiber box 3 located optical fiber ends with the provided plugs 30 are visible.

In the drawings, in particular in the exploded views 4 and 5, the connection-recess 41 is shown. This recess passes through the entire height of the optical network termination box 5 and is formed as a relative to the peripheral edge 5a inwardly offset wall 5a '. In the mentioned inwardly drawn, closed wall section 5a ¹ with the formation of the connection recess 41, the corresponding connection plug or connection plug connector (connection socket) is then formed at a corresponding point, into which the prepared plug connector sitting at the end of the glass fibers can be connected.

After attaching and attaching the network termination box 5 on the fiber box 3 can then depending on the system planning (whether, for example, one or two fiber systems or More are provided) the associated fiber connectors 30, so for example, a SC APC connector and the other there prepared and stored connectors from their respective tray in the storage chamber 103 "removed and raised in the recess 41, then at height of the recess 41 this Insert plug connectors into corresponding connections in the network termination box 5. For this purpose, corresponding sockets or sockets 39 are provided in the network termination box, preferably in the wall section 5a ¹ in the region of the recess 41.

The respective network termination box 5 is designed more or less as a closed overall housing, so that the end user is not accessible to the interior of the network termination housing 5, that is to say the so-called second chamber device 105 with the modules provided for the various services. Only on one longitudinal side 5c is so much space created by the mentioned recess 41 that the fibrous box 3 located therefrom and the opened access flap 34 provided thereon, the fiber optic ends with the connectors 30 in the second plane, i. inserted into the space of the terminal recess 41 of the network termination box 5 and connected to the terminals provided thereon laterally on a wall 5a ', i.e., the terminals of the terminal box 5; can be inserted. This alone is the relevant electrical connection, for example, for the transmission of TV channels, telephone calls, a connection to the Internet or to connected PCs, etc. produced.

The front still open connection recess 41 is then finally closed by a cover 47, which in the embodiment shown from one side to the one longitudinal side wall Ic the overall housing is plugged across, so that over this the network termination housing 5 and all laid therein cables are closed at the top to cover. As can be seen from the exploded drawing according to FIGS. 4 and 5, this end cover 47 is anchored to the upper shell of the net closure box 5 by, for example, tongue-shaped locking means 81, namely by corresponding tongues 81 'into corresponding receiving openings 81a engage in the upper shell 5 'of the network termination box 5 and vice versa tongue-like projections 81 "on the side wall 3 ^{1 of} the fiber box 3 engage in corresponding receptacles 83 on the end cover 47.

Furthermore, an information and display panel 49 with a large number of light-emitting diodes (LED) is provided on the upper side 6 of the network termination housing 5, that is to say display means in order to display the respective current operating state or status for the various services. This display panel 49 can be attached to a corresponding attachment point 49 'on the upper side 6 of the upper shell 5 ^{1 of} the network termination box 5 from above and can be electrically connected from the underside. Appropriate print variants are used to create the assignments for the respective product version. This means that it can be seen on the top of the lid which LEDs indicate which function.

At the second longitudinal side Id of the overall housing 1, at the level of the network termination housing 5, the already mentioned plurality of connection possibilities, for example a connection 151 for connection of a television / radio combination (CATV), four connections 153 for a computer network (LAN), one or two ports 155 for connection a telephone, etc. provided. Furthermore, in the exemplary embodiment shown, connection 157 for a power supply is also integrated (FIG. 1b).

Similarly, the network termination module 5, so the network termination box 5 include other modules, such as a module including an antenna for a wireless LAN (WLAN), SFP connector for connecting a fiber optic cable etc .. Restrictions are not so far.

In FIGS. 4 and 5, as mentioned, the overall housing 1 is shown in an exploded view, once in the direction of view from above and once from below. In these illustrations, the network termination box 5 is shown in the open state. In this case, a provided in the interior 105 of the box board 61 can be seen on the various modules 63 may be provided to realize the various desired services. In the exemplary embodiment shown, the network termination box 5 comprises the lower shell 5 "and the upper shell 5 'or the cover 5a, wherein the longitudinal side Id is formed as a separate wall Id, which can be inserted in a corresponding groove-shaped sliding guide on the transverse sides Box 5 is firmly closed by a plurality of screws 65 which can be screwed in from the outside of the lower shell 5 "and are thereby screwed into threaded columns 67 which are formed on the inside of the upper shell in the direction of the lower shell. If the sealed box 5 is placed on the fiber box 1 and fastened to it, the net box can not be opened from the outside. But any other attachment for anchoring the upper and lower shell 5 ', 5 "instead of screws is possible, for example, detent Also possible here is a non-destructive removal of the network termination box from the fiber box, for example, by corresponding locking tongues etc. can be adjusted in the open position.

The attachment of the network termination box 5 on the fiber box 3 by the already mentioned, on the fiber box lid 31 upwardly projecting guide pin 35, which are designed in side view L-shaped. These L-shaped guide pins 35 are inserted through corresponding slots 71 on the bottom, so the lower shell 5 "of the network termination box 5 and thereby the network termination box 5 can be moved according to the arrow 72 in the transverse direction so that the parallel to the bottom surface Ends 35 'of the guide pin 35 engage behind the narrower part of the longitudinal slot 71, so the box is thus firmly held and secured.

After the network termination box has been installed, a functional test is usually carried out, after which the functional test has been completed and the closure cover has then been hung and swiveled over the connection area. As a result, the entire device is ultimately closed and at the same time the network termination box is locked with the fiber box. A seal sticker can be additionally applied if necessary.

For this purpose, reference is made to the cross-sectional representation also according to Figure s 6 and 7. It can be seen that the bottom or bottom shell 5 "of the network termination box 5 have elastic latching fingers 107 with a corresponding undercut, and vice versa on the inside of one longitudinal side of the top shell 5 'of the network termination box 5 Bridge 109 is provided. If the closure lid 47 is inserted with its leading tongue-shaped latching means 81, 81 'in the corresponding recesses 81a on the upper shell 5' and the closure lid then at its verti cal lid portion 47 "(which is on the rather above lying transverse lid portion 47 ' adjoins) lowered, the inner web 109 runs on the wedge-shaped flank 107 'of the latching finger 107, so that the latching fingers can dodge inwardly until the fixed to the inside with the closure cover 47 web 109 engages the underside of the latching finger 107 and the 6 can swing back into its position shown in Figure 6. In this position then sets the transverse wall 47 "of the closure lid 47 at the upper edge of the fiber box on. In this position, the network termination box 5 is then firmly mounted on the fiber box 3 and can not be removed without destroying the housing of the fiber box 3. In addition, since the upper shell and the lower shell 5 ', 5 "of the network termination box 5 are firmly connected by means of screws located underneath, opening the fiber box without destruction, ie without destroying or damaging the housing, can not be carried out here It is also possible to attach the lid so that opening with a hand or a tool is possible without destruction, possibly only with difficulty, but in principle can be realized Seal may also be applied here to prevent third parties from opening the end cap.

At the same time, it can be seen from the cross-sectional illustration according to FIG. 7 that corresponding latching fingers 81 "at the upper edge of the fiber box can be inserted into the corresponding tongue-like form. ge recording 83 engage the lower edge of the closure lid 47, which also ensures that the closure lid 47 can not be deported to the rear.

As can be seen in particular from the rear view de Netzabschluss box 5, this can ultimately be used as a single-case (stand-alone). The at least one optical waveguide 17 for the modules integrated in the housing can be routed via a cable channel path 51 provided on the underside into the region of the connecting space 47 for the fiber cables, in which case this comparatively small in relation to the overall size or overall floor of the network termination housing The receiving space for the cable ends can be closed with a separate closure lid 53 at the bottom. If necessary, even rubber feet can be used on corresponding holes on the bottom, namely, when the housing is not mounted on a wall by means of screws, but for example, to be placed on a table or desk, so on a horizontal surface.
