    The invention relates to a splice module for connecting an optical waveguide with an optical waveguide coupling using a splice connection between the optical waveguide and a pigtail connecting conductor connected to the optical waveguide coupling, so that end sections of the optical waveguide and the pigtail connecting conductor are connected to one another to form a splice connection section , wherein the splice module has a carrier on which a splice connection holder for holding the splice connection section and / or a conductor guide arrangement for guiding the optical waveguide and / or the pigtail connecting conductor is arranged, the conductor guiding arrangement having at least one arched guiding section for arching the optical waveguide or the pigtail. Comprises connecting conductor with a predetermined minimum radius to limit attenuation in the respective conductor, with a bearing arrangement on a side edge region of the splice module for pivotable bearings of the splice module is arranged on a splice module base about a pivot axis which extends parallel to a base plane of the carrier in which the carrier has its greatest surface area, the invention further relates to a splice module arrangement which has at least one such splice module,
    The carrier of the splice module, for example a splice cassette, can thus be designed, for example, in the manner of a plate which is pivotably mounted on a splice module base. Several splice modules can be pivotably mounted next to one another on the splice module base, so that by pivoting one or more splice modules a space between adjacent splice modules is free, so that, for example, the support of a splice module is accessible for making a line connection or other assembly work. Such splice modules are used, for example, in house connections, in splice sleeves or the like.
    The splice cassette or the splice module thus enable an optical waveguide to be connected to a pigtail connecting conductor, at the end of which an optical waveguide coupling is arranged. The fiber optic coupling then enables a connection cable to be connected, for example. The fiber optic coupling is typically next to the splice module base, where it is easily accessible for connecting a fiber optic cable.
    However, the line routing, in particular the pigtail connection conductor, is cumbersome in the known technology.
    [0005] It is therefore the object of the present invention to provide an improved splice module.
    To achieve the object is provided in a splice module of the type mentioned that at least one coupling holder for holding the optical fiber coupling and / or the optical fiber coupling is arranged on the carrier.
    The handling of the splice module, especially when several splice modules are arranged on a splice module base, is significantly simplified. The at least one fiber optic coupling is available directly on the splice module for connecting a connection cable. The pigtail connection conductor is held on the support of the splice module, preferably even covered by a cover of the splice module, so that the optical waveguide or a cable with the optical waveguide leads into the splice module, but otherwise no cables, lines or the like from the interior of the splice module are to be led out into the environment. In addition, the pigtail connection conductor, which does not run freely in the vicinity of the splice module but is arranged directly on the carrier of the splice module, can be provided with minimal insulation, since it is not or only insignificantly exposed to environmental influences, mechanical damage or the like.
    The splice module can easily have a plurality of optical fiber couplings and / or a plurality of coupling holders suitable for this. Furthermore, the splice module can also be provided for connecting several optical waveguides to optical waveguide couplings. For example, the splice module has at least two, preferably on opposite sides, arranged cable inlets for optical waveguides.
    If several coupling holders and / or several optical fiber couplings are present, these are preferably arranged in one plane.
    For example, it is advantageous if the coupling holders and / or optical fiber couplings are arranged in the area of the base plane or on the base plane of the support of the splice module.
    It is true that the splice module, in particular its carrier, can be designed in a simple embodiment, for example in the manner of a card, cassette or plate.
    A housing-like configuration or a plate-shaped carrier protruding in front of the side walls are advantageous, however. In the case of the splice module, it is therefore advantageously provided that it has a module housing with a base body which forms the carrier and on which the conductor guide arrangement and / or the splice connection holder is arranged.
    It is advantageous if the splice connection holder is arranged in a stationary manner on the carrier, in particular its base body. The splice connection holder and the carrier or its base body are preferably firmly connected to one another, for example in one piece and / or firmly connected to one another by means of a fixed fixing, for example a snap-in fixing, a lock or the like.
    It if the splice module has only a single support and / or only a single base body is also advantageous. It is advantageous if both the splice connection holder and the at least one coupling holder or several coupling holders are arranged in a stationary manner on the support or base body.
    The carrier or the module housing of the splice module is preferably in one piece or in one piece.
    The carrier, in particular the module housing, is preferably made of plastic, in particular an electrically insulating plastic. Of course, other materials can also be used, also in combination, for example metal, in particular steel. For example, it is also possible for the carrier itself to consist of metal, in particular also the at least one coupling holder, while components arranged on the carrier, for example side walls, the splice connection holder, components of the conductor guide arrangement, for example guide projections, guide walls and the like Plastic can exist. It is advantageous if the at least one coupling holder and a base plate of the carrier are in one piece or from one piece.
    It is advantageous if the splice module has a cover, in particular a plate-like cover, for covering an interior of the module housing, the cover being opposite the base body in the state arranged on the module housing. The cover and the base body delimit an interior space in which, for example, the at least one pigtail connection cable is arranged in a protected manner. The cover completely or partially covers the interior of the module housing. Fastening means, for example latching means or the like, are advantageously used to hold the cover on the module housing. The lid preferably also covers the splice connector. The splice connection holder is preferably arranged on the base body and can be covered by the cover. The splice module preferably has only a single cover. The splice connection holder is preferably not arranged on the lid.
    It is advantageous if circumferential walls protrude in front of the carrier, in particular the base body. The peripheral walls form, for example, lateral side walls delimiting an interior space of the carrier or module housing.
    The peripheral walls project in front of the floor body and delimit an interior space. It is advantageous if the splice connection holder and / or the conductor guide arrangement is arranged in a stationary manner in the interior.
    The at least one coupling holder, the splice connection holder and the conductor guide arrangement are advantageously arranged one behind the other in a row direction and in a common plane.
    It is particularly advantageous if the at least one coupling holder is not covered or can not be covered by the splice connection holder.
    It is preferred if the at least one coupling holder and / or the optical fiber coupling is arranged on at least one circumferential wall which projects in front of the carrier, for example the base body. For example, the coupling holder is provided as an opening on the peripheral wall or side wall.
    The at least one coupling holder comprises, for example, a plug-in receptacle for plugging in the optical fiber coupling. For example, the coupling holder comprises a plug-in axis along which the optical fiber coupling can be inserted into the coupling holder, but rather the spaced-apart support walls on which a coupling housing of the optical waveguide coupling is positively supported transversely to the plugging direction. On the support walls, for example, through openings with an inner contour are provided which correspond to an outer circumferential contour of the clutch housing so that it can be supported in a form-fitting manner on all sides.
    Furthermore, it is advantageous if the coupling holder has at least one rear gripping surface or support surface for supporting a rear gripping body, for example a catch, a bolt, a supporting projection or the like, which protrudes from a coupling housing of the optical fiber coupling. For example, the coupling housing has a support projection on opposite sides, in particular a resilient support projection or a detent that engages behind the support surface or the coupling support when the optical fiber coupling is inserted into the coupling holder.
    The coupling holder includes, for example, a receiving chamber into which a coupling housing of the optical fiber coupling can be inserted.
    In the case of the splice module, it is advantageous if it has at least two or more coupling holders and / or optical fiber couplings, in particular those arranged next to one another in a row arrangement. It is preferred if the coupling housings of the optical fiber couplings have a flat shape and are arranged lying flat next to one another in the row arrangement. It is preferred if a respective optical waveguide coupling has two connections for an optical waveguide cable, for example plug connections, the connections being arranged next to one another in the row direction.
    It is advantageous if the at least one coupling holder or the optical fiber coupling, in particular a row arrangement of coupling holders or optical fiber couplings arranged next to one another, and the bearing arrangement on opposing and / or angled, in particular right-angled, side edge areas of the splice module or its carrier are arranged. It is of course possible for one or more coupling holders and / or optical fiber couplings to be arranged in each case on several side edge regions of the carrier. For example, the coupling brackets or fiber optic couplings can run around the carrier in a U-shape.
    The splice connection holder comprises, for example, several, in particular U-shaped and / or channel-like, receptacles arranged next to one another for the insertion of splice connection sections. The recordings are, for example, comb-like. A respective splice connection section is preferably arranged in a protective body, for example in a protective housing, a grommet, a shrink tube or the like. The receptacles of the splice connection holder are preferably designed to latch or clamp the splice connection section or a protective body arranged thereon in the receptacle.
    It is preferred if the splice connection holder is releasably attached to the carrier, for example by a plug connection, latching connection, screw connection or the like. The splice connection holder is, for example, plate-like
    It is preferably provided that the splice connection holder has, for example, receptacles for first splice connection sections and second splice connection sections on opposite sides, the first and second splice connection sections differing from one another, for example, geometrically. For example, the first splice connection sections can be provided for receiving first protective bodies, the second splice connection sections for receiving second protective bodies which differ geometrically from the first protective bodies, for example have a larger diameter or the like. Such a splice connection holder can, for example, be mounted in opposite positions on the carrier so that either the receptacles for the first splice connection sections or the receptacles for the second splice connection sections can be used.
    It is preferably provided in the splice module that the conductor guide arrangement has line receptacles for receiving the pigtail connecting conductor and / or the optical waveguide, which define an interior space in which the splice connection holder is arranged. The line receptacles thus run around the splice connection holder, for example, so that the conductors inserted or received in the respective line receptacles, i.e. the pigtail connection conductor or the optical waveguide or both, are guided around the splice connection holder.
    It is preferably provided in the splice module that the conductor guide arrangement, in particular arcuate guide sections, has for loop-shaped and / or arc-shaped guidance of the pigtail connection conductor and / or the optical waveguide around the splice connection holder.
    The splice connection holder is preferably arranged between the side edge area of the splice module having the bearing arrangement and an opposite side edge area of the splice module running parallel thereto. The at least one coupling holder and / or at least one optical waveguide coupling are preferably located on the side edge region of the splice module opposite the bearing arrangement.
    It is advantageous if the splice module has several, for example at least two, guide levels for guiding the respective lines. The line levels are preferably arranged in layers with respect to the base level of the carrier.
    At least two, preferably all, guide levels are advantageously immovable relative to one another. It is also advantageous if the splice connection holder is stationary with respect to at least two, preferably all, guide planes.
    The conductor guide arrangement expediently comprises a bottom guide plane, in particular for receiving a line section of the pigtail connection conductor to the fiber optic coupling provided, first guide plane above a base wall of the splice module, and a second guide plane having a greater distance from the base wall. The second guidance level is advantageously provided for guiding line sections leading to the splice connection holder.
    Thus, for example, pigtail connection conductors leading from the optical waveguide couplings arranged in a stationary manner on the splice module can be guided in the first guide plane on the bottom. It is advantageous if a first section of a respective pigtail connection conductor is arranged in the first guide plane on the bottom, while a second section of the pigtail connection conductor, which is further away from the optical fiber coupling and which is provided, for example, for connection to optical waveguides, i.e. to the splice connection holder should lead, is arranged in the more easily accessible second management level for the operator. Thus, so to speak, a line reserve or cable reserve of the pigtail connection conductor is arranged in the second guide level and can easily be removed from the splice module for splicing with the optical waveguide.
    In the case of the splice module, it is advantageously provided that the splice connection holder is arranged in the second guide plane, in particular in a stationary manner. Thus, for example, the power reserves of the optical waveguide and / or pigtail connection conductor can be guided to the splice connection holder in the second guide level.
    The conductor guide arrangement can for example have one or more support projections which protrude in front of the bottom wall. Guide channels or receiving channels for guiding or receiving sections of the pigtail connection conductor or optical waveguide can be provided between the support projections. It is also possible for the conductor guide arrangement to have support walls in a manner known per se. The already mentioned circumferential side walls or side walls of the module housing can also form components of the conductor guide arrangement.
    It is advantageous if support projections of the conductor guide arrangement protrude in front of the bottom wall, between which at least one guide channel of the first guide plane on the bottom runs and support surfaces for providing the second guide plane are provided on the sides facing away from the bottom wall or free end sides. Thus, so to speak, the spaces between the support projections for routing the line are provided in the first guide level, while support platforms or support surfaces for providing the second guide level are provided at the free end regions of the support projections, so to speak.
    In order to reliably hold line sections of the at least one pigtail connecting conductor or of the at least one optical waveguide, the conductor guide arrangement advantageously has one or more hold-down elements. For example, it is advantageous if the conductor guide arrangement has hook-like hold-down devices for holding the optical waveguide and / or the pigtail connection conductor in an interior space and / or in a bottom wall of the splice module on the opposite side. A respective hold-down device or hook-shaped hold-down device can be provided, for example, at a free end region of one or more of the aforementioned support projections, so that sections of the respective conductor resting on the support surface of the support projection are held by the hold-down device on the support projection.
    In a simple form, the splice module cannot contain the pigtail connecting conductor and the optical waveguide coupling. The splice module can, for example, be retrofitted with it.
    Pre-assembly is preferred, however. The pigtail connection conductor and / or the optical fiber coupling advantageously forms part of the splice module. For example, several optical fiber couplings and several pigtail connection cables are arranged on the carrier, so that the splice module is ready, so to speak, ready for assembly for connection to one or more optical fibers.
    It is advantageous if the pigtail connector runs in a kink protection grommet that protrudes in front of the optical fiber coupling. For example, the kink protection grommet is oriented along a plug-in axis along which a plug-in element can be plugged into the optical fiber coupling.
    [0045] The at least one pigtail connection conductor is protected from environmental influences by the splice module, in particular its module housing. The pigtall connection conductor advantageously contains a light guide which has an in particular colored insulation coating and is arranged in a cable sheath in a connection area connected to the light waveguide coupling or provided for connection to the light waveguide coupling. The section with the non-colored or colored insulation coating is used, for example, to connect to the optical waveguide.
    It is preferred if a length of the light guide in the cable jacket is at least ten times greater, preferably 20 times greater than a length of the light guide outside the cable jacket. The cable jacket is therefore short. The cable sheath can be accommodated in the anti-kink grommet already mentioned.
    It is advantageous if the light guide in the conductor guide arrangement runs essentially or exclusively outside the cable jacket. Starting from the fiber optic coupling, the light guide of the pigtail connection cable can be arranged in the splice module first within the anti-kink sleeve, then in the cable jacket and then, so to speak, freely, only isolated from the environment by its insulation coating. The section of the light guide coated only by the insulation coating is extremely flexible and therefore easily accessible for the assembly work, in particular for connection to the light waveguide, which is brought up to the splice module from the outside.
    The bearing arrangement of the splice module is preferably designed and provided for detachable mounting on the splice module base. For example, a plug-in installation on the splice module base is advantageous. However, it is entirely conceivable that the splice module is held captive on the splice module base, for example pivotably mounted on the splice module base by bearing elements that cannot be removed from the splice module base or can only be removed by an assembly process, for example screw mounting.
    It is preferred if the bearing arrangement in particular comprises bearing axle elements arranged integrally on a module housing of the splice module. The bearing axis elements can, for example, be inserted into bearing receptacles, bearing grooves, on the splice module base. The grooves are provided, for example, with resiliently flexible bearing projections into which the bearing axis elements of the module housing can engage.
    The splice module can form part of a splice module arrangement. The splice module arrangement comprises, for example, one or more splice modules according to the invention. The splice module arrangement further comprises a splice module base with a bearing receptacle for receiving the bearing arrangement of the at least one splice module, so that the at least one splice module is mounted on the splice module base such that it can pivot about the pivot axis.
    Preferably, at least one swivel stop for limiting the swivel movement of the splice module with respect to the splice module base to a swivel angle defined by the at least one swivel stop is arranged on the at least one splice module and / or on the splice module base. Thus, for example, a swivel angle of the splice module with respect to the splice module base can be limited to approximately 35-55 °.
    It is preferably provided that the splice module base has at least two bearing receptacles arranged in a row axis for the pivotable mounting of the at least one splice module and a further splice module, the splice modules being attached to pivot axes which are parallel to one another and to the row axis, in particular at right angles the bearing receptacles are mounted in a fan-like pivoting manner independently of one another, so that one splice module can be pivoted away from the other splice module and there is an angular distance between the base planes of the splice modules in which the splice connection holder is accessible to at least one of the splice modules. One or more of the splice modules are, for example, splice modules according to the invention. However, it is also possible for other splice modules not according to the invention to be pivotably mounted on the splice module base, for example those splice modules that only allow a pigtail connection conductor to be spliced with an optical fiber, but do not have an optical fiber coupling or coupling holder for it.
    In the splice module arrangement it is preferably provided that it has a protective housing in which the splice module base and the at least one splice module are arranged and / or that it forms part of a splice sleeve. The protective housing can, for example, comprise a floor which is suitable for wall mounting in a building and can be closed by a cover of the protective housing. The splice module base is preferably arranged on or formed by the floor. In the case of a splice sleeve, too, it is advantageous if it has a so-called base on which the splice module base is arranged, this base being able to be closed by a hood housing.
    An exemplary embodiment of the invention is explained below with reference to the drawing. Show it:<tb> <SEP> Figure 1 is a perspective oblique view of a splice module arrangement with two splice modules,<tb> <SEP> Figure 2 shows a detail D1 from Figure 1 to illustrate the bearing arrangement,<tb> <SEP> Figure 3 shows a splice module according to Figure 1 in a perspective oblique view from the front,<tb> <SEP> Figure 4 splice module according to Figure 3 from behind, and<tb> <SEP> FIG. 5 shows an enlarged detail D2 from FIG. 4.
    A splice module arrangement 10 comprises a splice module base 20, on which splice modules 40, 40B, which are structurally identical and, to this extent, are only provided with the reference symbol 40 in the following description, in a partially simplified manner.
    The splice module base 20 is advantageously received in a schematically indicated protective housing 11, in particular a protective hood of a splice sleeve or a house connection device. The splice module base 20 can, however, also be arranged on a so-called rack or frame.
    The splice module base 20 comprises a carrier body 21 with a bottom wall 22, from which side walls 23 protrude at an angle, for example at right angles. Between the side walls 23 there is a bearing body 30 or a bearing arrangement 30, which can be arranged integrally with the bottom wall 22, with a series arrangement of several bearing receptacles 31 for pivotably mounting the splice modules 40, 40B as well as further or other splice modules which are not shown in the drawing, arranged.
    The splice modules 40, 40B are mounted on the splice module base 20 so as to be pivotable about pivot axes S1, S2. The pivot axes S1, S2 run parallel to one another.
    In order to guide cables, optical waveguides or the like from the vicinity of the splice module base 20 to the splice modules 40B, the splice module base 20 has guide receptacles 26 that are limited, for example, by guide projections 24, 25 that are spaced from the bottom wall 22 and thus delimit a channel for receiving cables. The guide projections 24 project, for example, from the side walls 23 in the direction of the bearing receptacles 30 and thus the splice modules 40, while the guide projections 26 project opposite to this from the side of the bearing body 30 towards the guide projections 24. Between the guide projections 24, 25 there are spaces through which lines can be inserted into the guide receptacles 26.
    The splice modules 40 have supports 41 on which a bearing arrangement 50 for pivotably mounting the splice modules 40 on the splice module base 20 is arranged. The bearing arrangement 50 is arranged on a side edge area 48 of a respective carrier 41 and comprises bearing axle elements 51 which run between bearing projections 52, 53 which protrude in front of the carrier 41 and are integrally connected to the same. The bearing axis elements 51 extend along the pivot axes S1, S2 and can, so to speak, be locked into the bearing receptacles 31.
    The bearing receptacles 31 are provided between bearing projections 32 which protrude in front of the bottom wall 22. The bearing projections 32 are designed, for example, in the manner of tabs or plate-like projections. At the free end regions of the bearing projections 32, lead-in bevels 33 are preferably provided, on which the bearing axis elements 51 slide along for locking into the bearing receptacles 31 and can displace the bearing projections 32 away from one another.
    A projection 35 protrudes between rows 35 of bearing receptacles 31 that run parallel to one another and protrudes into a receptacle 54 of the bearing arrangement 50.
    Row axes of rows 35 are orthogonal to pivot axes S1, S2.
    The bearing projections 52, 53 are designed in the manner of bearing blocks. The bearing axis elements 51 are preferably integral with the bearing projections 52, 53.
    The carrier 41 is preferably designed as a module housing 47 or has one. The carrier 41 includes a plate-like bottom body 42 from which peripheral walls 43A protrude.
    The circumferential walls 43A comprise, for example, opposing side walls 43 which run with arcuate sections 44 towards the side edge region 48. Between the side walls 43, on the side of the carrier 41 opposite the side edge region 48, there extends a front side wall 45, on which a plurality of optical fiber couplings 90 are arranged, which can be distinguished as optical fiber couplings 90A, 90B, 90C, 90D, 90E, 90F.
    The side walls 43, in particular their curved sections 44, extend as far as a rear side wall 46 on which the bearing arrangement 50 is arranged.
    Thus, the optical fiber couplings 90 and the side edge region 48 are arranged on opposite sides of the carrier 41, so that the optical fiber couplings 90 are easily accessible.
    As indicated schematically with an optical fiber coupling 90G, it would also be possible, for example, for an optical fiber coupling to be arranged on one or both of the side walls 43.
    The optical waveguide couplings 90 arranged on the front side wall 45 or optical waveguide couplings 90 arranged on a side wall 43 are easily accessible in order to plug in a plug 151 of an optical waveguide connecting line 150 with an optical waveguide 152, for example. The optical fiber connection line 150 is used, for example, for data transmission into a building.
    The base body 42 extends in a base plane G of the carrier 41, in which the latter has its greatest surface area. The respective pivot axis S1, S2 runs parallel to the respective base plane G of the splice module 40, 40B. Thus, the splice modules 40, 40B can be pivoted away from one another in a fan-like manner, so that an interior space 49, for example of the module housing 42 of the splice module 40 as shown in FIG. 1, is easily accessible, for example for the splicing of optical waveguides explained below. However, it should be mentioned that the splice modules 40, 40B can be removed from the splice module base 20 at any time in order to carry out the assembly work and / or splice work explained below.
    A pivot stop 50A is provided on the splice module 40, for example, which limits pivoting of the splice module 40 on the splice module base 20 about the respective pivot axis S1 or S2 to a predetermined pivot angle, for example approximately 45 °. The pivot stop 50A is provided, for example, by an inclined surface on the rear side wall 46.
    The splice module 40, 40B is preferably preassembled, so to speak. The optical waveguide couplings 90A, 908, 90C, 90D, 90E, 90F are preferably already mounted on the carrier 41 before the optical waveguides are spliced, namely in coupling holders 80A, 80B, 80C, 80D, 80E, 80F, which are subsequently jointly used as coupling holders 80 are described. The coupling brackets 80A, 808, 80C, 80D, 80E, 80F are arranged on the front side wall 45.
    However, it would also be possible, in particular due to the simple plug-in assembly, to introduce the optical fiber couplings 90A, 90B, 90C, 90D, 90E, 90F into the coupling holders 80A, 80B, 80C, 800, 80E, 80F only when the The pigtail connection line 170 has already been spliced to the optical waveguide 100.
    The coupling brackets 80A. 80B, 80C, 800, 80E, 80F and / or the optical fiber couplings 90A, 908, 90C, 90D, 90E, 90F are arranged next to one another in a row axis R. The coupling holders 80A, 808, 80C, 80D, 80E, 80F form a row arrangement 85. The row axis R is parallel to the base plane G. The row axis R is parallel to a respective pivot axis S1 or S2.
    The optical waveguide couplings 90 have a coupling housing 91 which, on its free side protruding in front of the side wall 45, has plug receptacles 92 for inserting, for example, a plug 151 of an optical waveguide connecting line 150. Each fiber optic coupling 90 thus serves to connect two fiber optic connecting lines 150 to the splice module 40. The plug-in receptacles 92 are arranged next to one another along the row axis R.
    The coupling holders 80 have plug-in receptacles 89 with receiving chambers or holding receptacles 81 which are provided between the front side wall 45 and a wall 83 running parallel thereto. Side walls 82 delimiting the mounting receptacles 81 are provided between the front side wall 45 and the wall 83.
    Furthermore, a top wall or support wall 87 in the manner of a belt extends in the area of the front side wall 45 between the side walls 43 and delimits the holding receptacles 41.
    The side walls 82, but also the wall 83 and / or the front side wall 45 provide rear-engaging surfaces or support surfaces for latching projections 95 of the optical fiber couplings 90, which latch with the same when a respective coupling housing 91 is inserted into a coupling holder 80 . For example, the latching projections 95 are designed in the manner of resilient tabs or the like in a manner known per se. The latching projections 95 protrude in front of side walls 94 of the clutch housing 91.
    Push-through openings 84, 86 are provided on wall 83 and front side wall 45, through which a respective optical waveguide coupling 90, in particular its coupling housing 91, can be pushed, the latching projections 95 latching into the chamber-like holding receptacles 81. The through openings 84, 86 have an inner circumferential geometry which correlates with the outer circumferential geometry of the clutch housing 91, so that these are received in the through openings 84, 86 in a form-fitting manner.
    The coupling holders in 80 are preferably assigned indicators or labels 88 with which the individual coupling holders 80A, 80B, 80C, 80D, 80E, 80F and / or the optical fiber couplings 90A, 90B, 90C, 90D, 90E, 90F, in particular their respective plug-in receptacles 92 are individually labeled or indexed. The indicators or labels 88 are preferably arranged on the top wall or support wall 87.
    On their sides opposite to the plug receptacles 92, the coupling housings 91 have connections 93, to each of which a pigtail connection conductor 170 is connected. A kink protection grommet 96, in which the pigtail connection line 170 runs, is preferably firmly connected to a respective connection 93.
    The pigtail connecting conductors 170, one of which is shown as an example, have an optical waveguide 171, of which a section or connection area connected to the optical waveguide coupling 90 runs in a cable sheath 172. The cable sheath 172 is preferably firmly connected to the kink protection grommet 96 and / or runs in the kink protection grommet 96.
    The cable sheaths 172 are, however, very short and only extend as far as a conductor guide arrangement 60, by means of which the individual light guides 171 are guided or received in an orderly manner in the interior 49 of the splice module 40.
    The light guide 171 is preferably provided with an insulation coating, in particular a colored insulation coating, but this is not visible in the drawing. Each light guide 171 is thus color-coded and can be easily identified within the conductor guide arrangement 60 or in the area of a splice connection holder 55. It is also advantageous if the cable sheath 172 has the same color as the insulation coating of the light guide 171 accommodated in it.
    In each case a light guide 171 is to be connected to an optical waveguide 100, which is guided from the outer region of the splice module 40 into its interior 49. Of course, the optical waveguide 100 can comprise several optical waveguides, each of which is to be connected to an optical waveguide 171. Only a single light guide is shown as an example.
    The fiber optic 171 of the pigtail connecting conductor 170 is thus connected to the fiber optic 100 at its end region facing away from the fiber optic coupling 90, namely by means of a splice connection, so that the two conductors form a splice connecting section 105.
    The splice connection section 105 is advantageously protected by a protective body, in particular a shrink tube or the like, but this is not shown in the drawing.
    The splice connection section 105, in particular a protective body sheathing it, can for example be inserted into a receiving channel 57 of the splice connection holder 55, in particular it can be snapped into place or clamped.
    The splice connection holder 55 has a plurality of receiving grooves 57 running parallel to one another for receiving one splice connection section 105 each.
    The receiving grooves 57 run, for example, parallel to the row axis R and / or parallel to the pivot axis S1, S2, although this is not absolutely necessary.
    The receiving grooves 57 are provided on a plate body 56 of the splice connection holder 55. The plate body 56 has on opposite large-area sides or flat sides in each case an arrangement of a plurality of receiving channels 57, which, however, can have different widths or otherwise different geometries. The plate body 56 can be detachably mounted in opposing orientations on the carrier 41, so that the respectively required receiving grooves 57 for receiving splice connection sections 105 are available. The plate body 56 has, for example, a holder 58 which comprises, for example, a receiving opening into which a retaining projection 59 protruding from the carrier 41, in particular the base body 42, engages, in particular in the manner of a latching connection.
    The conductor guide arrangement 60 comprises a series of support projections 61, 62 protruding from the base body 42, between which support projections 63 are arranged.
    [0094] Row arrangements of the respective support projections 61, 62 and 63 advantageously run along a row axis which is parallel to the row axis R.
    The support projections 61, 62 are arranged in a row next to one another and lie opposite the optical waveguide couplings 90.
    The supporting projections 63 are arranged at a greater distance from the optical waveguide couplings 90.
    Guide receptacles 64 for receiving pigtail connection conductors 170 are formed between the support projections 61, 62 and the support projections 63 further away from the optical waveguide couplings 90.
    The guide receptacles 64 run obliquely to a support wall 65 which lies opposite the support projections 63. Between the support projections 63 and the support wall 65, a channel 66 is formed, which merges into a channel-like curved guide section 67, which is formed between the peripheral walls 43A, specifically for example the curved sections 44 of the side walls 43, and an at least partially curved support wall 68, which is the side wall 43 opposite.
    The arc guiding section 67 has a minimum radius of curvature which does not allow a curvature of the light guide received therein beyond a minimum. The light guide can therefore not be curved more than is specified by the curved guide section 67. As a result, attenuation caused by a curvature of the light guide is low.
    The pigtail connection conductors 170 are guided away from the optical waveguide couplings 90, initially along the base body 42 or above a base wall 69 in a guide plane E1. For example, the guide receptacles 64, the channel 66 and the sheet guide section 67 run in the guide plane E1.
    At a greater distance from the base body 42, a guide plane E2 is provided, into which the pigtail connection lines 170 can be guided. For the sake of simplicity, this is not shown in the drawing. The guide plane E2 comprises, for example, a support surface 70 which is at a distance from the bottom wall 69. The support surface 70 is provided on a kind of pedestal, for example. In front of the support surface 70, there are support walls 71 which are opposite the support walls 68. Thus, between the support walls 71, 68, channel-like arcuate guide sections 72 are formed which are suitable for receiving the pigtail connection lines 170 and / or the optical waveguides 100.
    In the same plane as the support surface 70, support surfaces 73 are located on the support projections or on the free end regions of the support projections 61, 62, 63. Thus, lines can pass over the channel 66 from the support surface 70 onto the support projections 61, 62, 63 be guided.
    Hold-down devices, in particular hook-shaped hold-down devices, hold the respective lines in the cavities of the conductor guide arrangement 60. For example, hold-down devices 75 protrude into the sheet guide sections 72 in front of the support walls 66, 68, with insertion slots for inserting cables into the sheet guide sections 72 between the hold-down devices 75 available. Furthermore, for example, hook-shaped hold-down devices 76 are advantageously provided on the support projections 61-63.
    Inlets 74 for optical waveguides 100 are provided on the side edge region 48. The inlets 74 are preferably located in the guide plane E1 and are provided, for example, between the side walls 43 and the rear side wall 46.
    A section 101 of an optical waveguide 100 is introduced into one of the inlets 74, for example, and a section 102 extends between the rear side wall 46 and the splice connection holder 55 into that curved guide section 72 opposite the inlet 74. There, the optical waveguide 100 is guided in a curved manner in a section 103 and then runs further over the support projections 63 into the opposite curved guide section 72 and out of it in a generous arc with a small radius of curvature to the splice connection holder 55 and thus to the splice connection section 105 in .
    It can be seen that the lines of optical waveguide 100 and pigtail connecting line 170 are looped or arched around the splice connection holder 55 through the conductor guide arrangement 60, so that on the one hand the splice connection holder 55 is easily accessible and on the other hand the radii of curvature of the lines are small.
    Preferably, a partially schematically indicated, in particular plate-like, cover 12 is provided, with which the interior 49 can be completely or substantially covered. The cover 49 can, for example, be clamped, latched or connected in some other way to the peripheral walls 43A. In particular, latching projections or support projections 13 are provided for locking the cover 12 to the module housing 47 and / or for supporting the cover 12.
