Abstract

The use of lines of optical fibres in communication systems requires additional space in structural frameworks in order to avoid mixing electrical and optical cables. The invention solves this problem by providing a large-surface carrier (1) between the rear part of the assembly carrier and the door (5) of the cabinet. The large-surface carrier is used to accommodate optical system components (2, 3).

Description

Beschreibungdescription
Vorrichtung zur Leitungsführung in KommunikationsSystemen.Device for routing cables in communication systems.
Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a device according to the preamble of claim 1.
Bei zeitgemäßen Kommunikationssystemen besteht das Problem, die zu verarbeitenden Informationssignale einer Vielzahl von systeminternen Einrichtungen zuzuführen. Dies gilt insbesondere für die Koppelfeldbaugruppen eines ATM-Kommunikationssystems die räumlich eng nebeneinander angeordnet sind.In contemporary communication systems, there is the problem of supplying the information signals to be processed to a large number of system-internal devices. This applies in particular to the switching matrix modules of an ATM communication system which are spatially closely arranged.
Da Übertragungsraten von 3,3 Gbit/s und mehr nicht mehr effizient über elektrische Leitungen geführt werden können, wird daher die Zuführung der Informationssignale über Lichtwellenleiter realisiert. Letztere sind in der Regel als optische (Glas) Faserleitungen ausgebildet.Since transmission rates of 3.3 Gbit / s and more can no longer be conducted efficiently via electrical lines, the information signals are therefore supplied via optical fibers. The latter are usually designed as optical (glass) fiber lines.
In der Vermittlungstechnik werden beim Stand der Technik Gestellrahmen (Rack) verwendet. In diesen sind die Bauelemente tragende Baugruppen in Baugruppenträgern angeordnet .Die elek- trische Verkabelung wird über die Decke und/ oder den Boden der Gestellrahmen an die Baugruppenträger im Bereich der Rückseite herangeführt.In switching technology, rack frames are used in the prior art. In these, the component-carrying assemblies are arranged in subracks. The electrical cabling is brought up to the subracks in the area of the rear via the ceiling and / or the bottom of the frame.
Mit der Verwendung von Glasfasern ist nun zusätzlicher Raum- bedarf erforderlich. Ein Kabelmix von Glasfaserleitungen und elektrischen Kabeln würde die flexiblen Glasfaserleitungen zwischen den relativ starren elektrischen Kabeln in Undefinierter Weise knicken und dadurch Übertragungsfehler erzeugen. Aus diesem Grund sind die Glasfaserleitungen gesondert zu verlegen, wozu jedoch entsprechend Raum benötigt wird. Dieser zusätzliche Raumbedarf steht jedoch in den Gestellrahmen nur eingeschränkt zur Verfügung. Zusätzlich müssen die Glasfaserleitungen noch mit genügend Spielraum in der Länge (Spleißreserve) versehen werden. Dieses als Reserve gehaltene Leitungsmaterial muß noch zusätzlich untergebracht werden.With the use of glass fibers, additional space is now required. A cable mix of fiber optic cables and electrical cables would kink the flexible fiber optic cables between the relatively rigid electrical cables in an undefined manner and thereby generate transmission errors. For this reason, the fiber optic cables have to be laid separately, which requires space. However, this additional space requirement is only available to a limited extent in the frame. In addition, the fiber optic cables must be provided with sufficient scope in terms of length (splice reserve). This line material, which is kept as a reserve, must also be accommodated.
Weiterhin sind noch optische Leistungsteiler (optische Verzweiger) in die optische Verkabelung zu integrieren. Da der Ausbauzustand des Kommunikationssystems die Anzahl der Glas- faserleitungen und optischen Leistungsteiler definiert, ist damit entsprechend Raum für Erweiterungszwecke vorzusehen.Furthermore, optical power dividers (optical splitters) have to be integrated into the optical wiring. Since the state of expansion of the communication system defines the number of fiber optic cables and optical power dividers, space must be provided accordingly for expansion purposes.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung aufzuzeigen, mittels der die Führung optischer Glasfaserleit- ungen in einem KommunikationsSystem in praktikabler Weise durchführbar ist .The invention is based on the object of demonstrating a device by means of which the routing of optical glass fiber lines in a communication system can be carried out in a practical manner.
Die Erfindung wird, ausgehend von dem Oberbegriff des Patentanspruchs 1 durch dessen kennzeichnende Merkmale gelöst.The invention is achieved on the basis of the preamble of claim 1 by its characterizing features.
Vorteilhaft an der Erfindung ist insbesondere, daß daß im Bereich der Rückfront ein großflächiger Träger zur Aufnahme der Systemkomponenten angeordnet ist. Damit ist der Vorteil verbunden, daß eine stufenweise Systemerweiterung in effi- zienter Weise gebenen ist, ohne daß es zu ungeordneten Verhältnissen bei der Kabelführung kommt.A particular advantage of the invention is that a large-area support for accommodating the system components is arranged in the area of the rear front. This has the advantage that there is a gradual system expansion in an efficient manner, without there being disorderly conditions in the cable routing.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben .Advantageous developments of the invention are specified in the subclaims.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert. Es zeigenThe invention is explained in more detail below using an exemplary embodiment. Show it
FIG 1 ein Gestellrahmen, in dem die erfindungsgemäße Vorrichtung angeordnet ist,1 shows a frame in which the device according to the invention is arranged,
FIG 2 ein großflächiger Träger mit optischen Verzweigern2 shows a large-area carrier with optical branches
Gemäß Fig.l ist ein Gestellrahmen (Rack) 7 aufgezeigt, in dem eine Mehrzahl von Baugruppen angeordnet sind. Letztere sind in Baugruppenträger 10 zusammengefaßt, deren Rückseite Fig. 1 entnehmbar ist . Dort werden optische Informationssignale über eine optische Verkabelung 6 und optische Verbinder 11 sowie elektrische Informationssignale über eine elektrische Verkabelung 8 und elektrische Verbinder 9 im Bereich der Rückfront an die Baugruppenträger und damit die Baugruppen herangeführt .According to Fig.l, a rack 7 is shown, in which a plurality of assemblies are arranged. The latter are combined in subracks 10, the rear side of which can be seen in FIG. 1. There, optical information signals are brought to the subrack and thus the subassemblies via optical cabling 6 and optical connectors 11 and electrical information signals via electrical cabling 8 and electrical connectors 9 in the area of the rear front.
Weiterhin ist Fig. 1 eine Mehrzahl von Systemkomponenten entnehmbar. Dabei handelt es sich um Verzweigerkassetten 2 sowie Wickelkörper 3. Die Verzweigerkassetten 2 dienen der Aufnahme von optischen Leistungsteilern oder optischen Verzweigern, während die Wickelkörper 3 der Aufnahme der Glasfaserleitungen 4 sowie der vorgehaltenen Spleißreserve dienlich sind.1 shows a plurality of system components. These are branch cassettes 2 and winding bodies 3. The branch cassettes 2 serve to accommodate optical power dividers or optical branching devices, while the winding bodies 3 are used to accommodate the fiber optic lines 4 and the splicing reserve.
Verzweigerkassetten 2 sowie Wickelkörper 3 sind auf einem großflächigen Träger 1 kantenparallel angeordnet. Die Anordnung weist damit die Form einer Matrix auf . Der großflächige Träger 1 ist im Bereich der Rückfront des Gestellrahmens 7 schwenkbar auf Drehangelzapfen angeordnet. Hinter dem groß- flächigen Träger kann vorzugsweise eine gleichfalls schwenkbare Schranktür 5 vorgesehen werden.Branch cassettes 2 and winding body 3 are arranged on a large-area carrier 1 parallel to the edges. The arrangement thus has the shape of a matrix. The large-area support 1 is arranged in the region of the rear front of the frame 7 so that it can pivot on pivot pins. A cabinet door 5, which can also be pivoted, can preferably be provided behind the large-area support.
Die zu Reservezwecke gehaltene Überlänge der Glasfaserleitungen 6 werden gemäß Fig. 1 über die Wickelkörper 3 geführt. Diese sind aus elastischen, nicht brennbaren Schaumstoff-The excess length of the glass fiber lines 6 held for reserve purposes is guided over the winding body 3 according to FIG. 1. These are made of elastic, non-flammable foam
Formteilen mit Selbstkleberücken gebildet. Die Wickelkörper 3 werden fest aneinanderliegend befestigt. Die Wickelfläche der Wickelkörper werden entsprechend dem minimal zulässigen Biegeradius für Glasfaserleitungen verrundet. Damit wird der Fa- serwikel zwischen den Wickelkörpern festgehalten ohne daß die Glasfaserleitung geknickt, geklemmt oder stark auf Zug bean- sprucht wird.Molded parts formed with self-adhesive backing. The winding body 3 are firmly attached to each other. The winding area of the Winding cores are rounded according to the minimum permissible bending radius for fiber optic cables. The fiber particle is thus held between the bobbins without the fiber optic cable being kinked, clamped or subjected to excessive tensile stress.
In Fig. 2 ist der großflächige Träger 1 detaillierter aufgezeigt. Demgemäß werden die Verzweigerkassetten 2 in schlitzförmige Durchbrüche 12 des Trägers 1 gesteckt. Letztere bil- den komplementär zu den Einhängevorrichtungen der Verzweigerkassetten gebildete Einhgängevorrichtungen. Jede Verzweigerkassette weist vorzugsweise 4 nach unten gekröpfte Einhängevorrichtungen auf, welche in die jeweils komplementär dazu ausgebildete Einhängevorrichtung des Trägers 1 aufgenommen sind. Damit sind die Verzweigerkassetten 5 lösbar mit dem großflächigen Träger 1 verbunden.2, the large-area carrier 1 is shown in more detail. Accordingly, the branch cassettes 2 are inserted into slot-shaped openings 12 in the carrier 1. The latter form single-path devices which are complementary to the hook-in devices of the branch cassettes. Each branch cassette preferably has 4 hooked-down hooking devices which are accommodated in the hooking device of the carrier 1 which is designed to be complementary thereto. The branch cassettes 5 are thus detachably connected to the large-area carrier 1.
Auf Grund der großen Montagefläche des Trägers 1 lassen sich die einzelnen Systemkomponenten übersichtlich anordnen. Grund- sätzlich können beliebige Systemkomponenten aufgenommen werden, die Erfindung ist somit nicht auf die Aufnahme von optischen Verzweigerkassetten und Wickelkörper beschränkt. Insbesondere sind hier solche Systemkomponenten anordenbar, die im Zuge einer Erweiterung lediglich kundenspezifisch benötigt werden und und sich aufgrund ihrer Formgebung oder Funktion nicht ohne weiteres als Baugruppe integriert werden können. Due to the large mounting area of the carrier 1, the individual system components can be arranged clearly. In principle, any system components can be accommodated, and the invention is therefore not restricted to accommodating optical branch cassettes and winding bodies. In particular, such system components can be arranged here that are only required in a customer-specific manner during the course of an expansion and, because of their shape or function, cannot easily be integrated as an assembly.
