Abstract

The invention relates to a distribution network for the simultaneous transmission of broadband and narrowband services for optical fibres. The object of describing a service-optimised distribution network of this type with which both narrowband and broadband services can be transmitted in an economically optimum fashion is achieved by installing a star-type network with low-cost optical fibres for the narrowband services and a tree-type network with high-quality optical fibres for the broadband services together in one cable. <IMAGE>

Description

Verteilnetz für die gleichzeitige Übertragung von Breitband- und Schmalbanddiensten über Lichtleitfasern Die Erfindung betrifft ein Veteilnetz für die gleichzeitige Übertragung von Breitband- und Schmalbanddiensten über Lichtleitfasern, wobei für die Breitbanddienste ein Baumnetz und für die Schmalbanddienste ein Sternnetz vorgesehen ist. Distribution network for the simultaneous transmission of broadband and Narrowband services via optical fibers The invention relates to a distribution network for the simultaneous transmission of broadband and narrowband services via optical fibers, a tree network for broadband services and a star network for narrowband services is provided.

Aus "Unterrichtsblätter der Deutschen Bundespost, Jg. 35, 1982, Nr. 3, Seite 142, Kapitel 2.3, Bk-Verteilnetz", ist es bekannt, daß für ein Dialognetz, d.h. für Schmalbanddienste ein Sternnetz erforderlich ist, während für das überwiegend in Verteilrichtung betriebene Breitbandnetz die weitaus kostengünstigere Baumstruktur gewählt werden kann.From "Lehrsblätter der Deutsche Bundespost, vol. 35, 1982, no. 3, page 142, chapter 2.3, Bk distribution network ", it is known that for a dialogue network, i.e. a star network is required for narrowband services, while predominantly Broadband network operated in the distribution direction uses the much more cost-effective tree structure can be chosen.

Der Erfindung liegt die Aufgabe zugrunde, ein dienstoptimiertes Verteilnetz anzugeben, mit dem sowohl Schmalbanddienste als auch Breitbanddienste auf wirtschaftlich optimale Weise übertragen werden können.The invention is based on the object of a service-optimized distribution network indicate with which both narrowband services and broadband services are economical can be transmitted in an optimal manner.

Die Aufgabe wird gelöst wie im Anspruch 1 beschrieben. Der Unteranspruch gibt eine vorteilhafte Weiterbildung an.The object is achieved as described in claim 1. The subclaim indicates an advantageous further development.

Im folgenden sei die Erfindung anhand eines Ausführungsbeispiels mit Hilfe von zwei Figuren näher erläutert: Figur 1 zeigt wie das Sternnetz und das Baumnetz bis zum Teilnehmeranschluß parallel geführt ist, und sich das Baumnetz erst in der Abzweigmuffe aufspaltet.In the following the invention is based on an exemplary embodiment Explained in more detail with the help of two figures: Figure 1 shows how the star network and the Tree network is led in parallel to the subscriber connection, and the tree network only splits in the branch joint.

Figur 2 zeigt eine Variante, bei der das Sternnetz und das Baumnetz nur bis zum Kabelverzweiger parallel geführt ist, und nur eine Faser vom Kabelverzweiger bis zum Teilnehmeranschluß geführt ist; gestrichelt ist angedeutet, daß alternativ dazu auch hier zwei Fasern zum Teilnehmeranschluß zugeführt werden können.Figure 2 shows a variant in which the star network and the tree network is only run in parallel up to the cable distributor, and only one fiber from the cable distributor is led to the subscriber line; dashed lines indicate that alternatively here, too, two fibers can be fed to the subscriber line.

Die in den Figuren benutzten Abkürzungen bedeuten: AtM = Aufteilmuffe, AzM = Abzweigmuffe, BD = Breitbanddienste, BN = Baumnetz, Hk = Hauptkabel, K = Kommunikation, KVz = Kabelverzweiger, M = Teilnehmerzahl, An = Anzahl der Verzweigungskabel, OV = Optischer Verzweiger, SD = Schmalbanddienste, SN = Sternnetz, Sp = Speisestelle, Tan = Teilnehmeranschluß, V = Verteilung und VzK = Verzweigungskabel.The abbreviations used in the figures mean: AtM = distribution socket, AzM = branch joint, BD = broadband services, BN = tree network, Hk = main cable, K = communication, KVz = cable distributor, M = number of participants, An = number of branch cables, OV = Optical splitter, SD = narrowband services, SN = star network, Sp = feed point, Tan = subscriber connection, V = distribution and VzK = branch cable.

Der wesentliche Vorteil der Erfindung besteht darin, daß für das Sternnetz billige Fasern verwendet werden können und nur die wenigen Fasern für das Baumnetz von höherer Qualität sein müssen. Man erreicht dadurch eine beachtliche Reduzierung der Kosten. Da das Stern- und das Baumnetz in einem Kabel vereint sind, muß nur ein Kabel verleyt werden.The main advantage of the invention is that for the star network cheap fibers can be used and only the few fibers for the tree network must be of higher quality. This results in a considerable reduction the cost. Since the star and tree network are combined in one cable, you only have to a cable can be laid.

Patentansprüche 1. Verteilnetz für die gleichzeitige Übertragung von Breitband- und Schmalbanddiensten über Lichtleitfasern, wobei für die Breitbanddienste ein Baumnetz und für die Schmalbanddienste ein Sternnetz vorgesehen ist, dadurch gekennzeichnet, daß für die Schmalbanddienste je eine billige Lichtleitfaser pro Teilnehmer mit geringer Qualität vorgesehen ist, daß für die Breitbanddienste eine qualitativ hochwertige Lichtleitfaser für u Teilnehmer vorgem sehen ist, wobei u = Teilnehmerzahl und m = Anzahl der Verzweigungskabel ist, und daß das Sternnetz und das Baumnetz gemeinsam in einem Kabel untergebracht und damit von der Speisestele bis zum Teilnehmeranschluß oder nur bis zum Kabelverzweiger parallel verlegt sind.Claims 1. Distribution network for the simultaneous transmission of Broadband and narrowband services via optical fibers, whereby for broadband services a tree network and a star network is provided for narrowband services, thereby characterized that a cheap optical fiber per each for the narrowband services Subscribers with low quality is provided that one for the broadband services high quality optical fiber for u subscribers can be seen, with u = Number of subscribers and m = number of branch cables, and that the star network and the tree network housed together in a cable and thus from the dining stele are laid in parallel up to the subscriber connection or only up to the cable distributor. 2. Verteilnetz nach Anspruch 1, dadurch gekennzeichnet, daß in dem Fall, in dem das Sternnetz und das Baumnetz nur bis zum Kabelverzweiger parallel geführt ist, nur eine qualitativ hochwertige Lichtleitfaser vom Kabelverzweiger bis zum Teilnehmer anschluß geführt ist und das Sternnetz und das Baumnetz mit Hilfe eines optischen Verzweigers im Kabelverzweiger in diese eine Lichtleitfaser zusammengeführt sind.2. Distribution network according to claim 1, characterized in that in the Case in which the star network and the tree network are only parallel to the cable distributor is out, only a high quality optical fiber from the cable distributor until the subscriber connection is performed and the star network and the tree network with the help An optical splitter in the cable splitter merged into this one optical fiber are.
