Abstract

The two-part coupling for aligned optical fibres has a sleeve for each fibre (4, 14). The sleeve (8, 18) is capable of adjustment by means of an elastically (5, 15) supported mounting (7, 17) which is arranged eccentrically in the housing. A photodiode (1) is inserted between the front faces of the fibres (4, 14) such that light transmitted via the fibres can pass through suitable openings (3, 13) in the metalligation of the diode contacts. These are connected to and supported by a strip line (11, 12) which is designed as a separate, interchangeable component in the coupling. The openings (3, 13) are provided with immersion solution.

Description

Kupplung für zwei fluchtende Lichtleitfasern Coupling for two aligned optical fibers

Die Erfindung befaßt sich mit einer Kupplung für zwei fluchtende Lichtleitfasern, die in einem zweiteiligen Kupplung gehäuse angeordnet sind, und hat zur Aufgabe eine Anordnung, mit welcher die Fasern einfach justiert werden können und gleichzeitig ein Teil der in den Fasern geführten optischen Leitung in elektrische Signale umgewandelt werden können.The invention relates to a coupling for two aligned optical fibers, which are arranged in a two-part clutch housing, and has the task an arrangement with which the fibers can be adjusted easily and at the same time part of the optical line routed in the fibers is converted into electrical signals can be.

Gelöst wird dies dadurch, daß jede Faser in einer Hülse gehaltert ist, die ihrerseits durch eine elastisch gelagerte, exzentrisch im Gehäuse angeordnete Halterung justierbar ist und daß gleichzeitig zwischen den Stirnflächen der Fasern eine Fotodiode derart eingefügt ist, daß das über die Faser übertragene Licht durch geeignete Öffnungen in der Metallisierung der Diodenkontakte hindurchtreten kann und daß diese Diodenkontakte mit einer sie halternden Streifenleitung verbunden sind, welche als getrenntes Bauteil in der Kupplung auswechselbar ausgebildet ist.This is achieved by holding each fiber in a sleeve is, in turn, by an elastically mounted, eccentrically arranged in the housing Bracket is adjustable and that at the same time between the end faces of the fibers a photodiode is inserted so that the light transmitted through the fiber through suitable openings in the metallization the diode contacts pass through can and that these diode contacts are connected to a strip line holding them which is designed as a separate component in the coupling so that it can be replaced.

Die Ausbildung der eingefügten, mit den Fasern gekoppelten Fotodiode als getrenntes1 auswechselbares Bauteil ermöglicht ein einfaches Auswechseln der Diode, so daß Jeweils ein vorbestimmter Anteil des hindurchtretenden Lichts dadurch absorbiert wird, daß man die Dicke der Diode und das Diodenmaterial entsprechend wählt. Man kann somit einen Teil der in der Faser geführten optischen Leitung direkt in elektrische Signale umwandeln, ohne daß dafür optische Koppler notwendig sind.The formation of the inserted photodiode coupled with the fibers As a separate1 replaceable component, the Diode, so that in each case a predetermined proportion of the light passing through it is absorbed by adjusting the thickness of the diode and the diode material accordingly chooses. Part of the optical line routed in the fiber can thus be used directly convert them into electrical signals without the need for optical couplers.

In der Fig. 1 ist eine gemäß der Erfindung aufgebaute Anordnung im Schnitt dargestellt. Xtt 4 bzw. 14 sind dabei die beiden Lichtleitfasern bezeichnet, die in dem zweiteiligen Gehäuse 6 miteinander gekoppelt werden sollen. Die Fasern werden in Hülsen 8 bzw. 18 gehaltert. Diese können durch exzentrisch im Gehäuse angeordnete Halterungen 7 bzw.In Fig. 1, an arrangement constructed according to the invention is in Section shown. Xtt 4 and 14, the two optical fibers are designated, which are to be coupled to one another in the two-part housing 6. The fibers are held in sleeves 8 and 18, respectively. This can be done eccentrically in the housing arranged brackets 7 resp.

17 justiert werden mit Hilfe der im Gehäuseumfang um 1200 gegeneinander versetzt angebrachten Schrauben 10 bzw. 16.17 can be adjusted with the help of the housing circumference around 1200 against each other offset screws 10 or 16.

Die Halterungen 7 und 17 sind gegenüber dem jeweiligen mittleren Gehäuseboden durch elastische Zwischenlagen 5 und 15 getrennt. Durch entsprechendes Verdrehen der erwähnten Schrauben wird es somit möglich, die beiden Lichtleitfasern 4 und 14 so auszurichten, daß sie miteinander fluchten.The brackets 7 and 17 are opposite the respective middle housing base through elastic intermediate layers 5 and 15 separately. By appropriate Turning the screws mentioned makes it possible to use the two optical fibers 4 and 14 so that they are flush with one another.

Die Diode 1, welche zwischen den Stirnflächen der beiden Lichtleitfasern 4 und 14 eingefügt wird, hat in der ober-und unterseitigen Metallisierung 19 und a0 geeignet dimensionierte Aussparungen 3 und 13, durch die das über die Faser übertragene Licht in die Diode eintreten kann. In der Fig. 2 ist der Aufbau einer solchen Diode 1 schematisch dargestellt. Die Diodenoberflächen können dabei im Bereich der Öffnungen vergütet sein, wie dies bei 2 angedeutet ist. Ferner ist es vorteilhaft, die Öffnungen 3, 13 der Diode im eingebauten Zustand mit einer Immersionslösung zu versehen. Die Diode selbst wird gehaltert in einer StreifenleXtung 11, 12, welche zwischen den beiden Hälften des Kupplungsgehäuses 6 eingefügt ist. Die Justierung erfolgt so, daß nach Einfügen des Streifenleiters 11, 12 mit der entsprechend ausgesuchten Diode 1 dann die Lichtleitfasern 4, 14 in der bereits beschriebenen Weise justiert werden, um eine optimale Übertragung zu gewährleisten. Sind die Fasern bezüglich Abstand und Richtung ju stiert, so können sie in ihrer Lage mit Hilfe der Befestigungeschrauben 10 und 16 fixiert werden.The diode 1, which is between the end faces of the two optical fibers 4 and 14 is inserted, has in the top and bottom metallization 19 and a0 suitably dimensioned recesses 3 and 13 through which the transmitted via the fiber Light can enter the diode. 2 shows the structure of such a diode 1 shown schematically. The diode surfaces can be in the area of the openings be remunerated, as indicated at 2. It is also advantageous to use the openings 3, 13 to provide the diode with an immersion solution when installed. the Diode itself is held in a strip cable 11, 12, which is between the two halves of the coupling housing 6 is inserted. The adjustment is carried out in such a way that after inserting the strip conductor 11, 12 with the appropriately selected diode 1 then the optical fibers 4, 14 are adjusted in the manner already described, to ensure optimal transmission. Are the fibers in terms of spacing and direction ju so they can be in their position with the help of the Fixing screws 10 and 16 are fixed.

Die Anordnung kann auch nur zur Durchverbindung von den beiden Lichtleitfasern 4 und 14 benutzt werden, wenn die Streifenleitung 11, 12 eo ausgebildet ist, daß an Stelle der Diode 1 eine für die Verbindung der beiden Fasern entsprechend dimensionierte Aussparung vorhanden ist, 8o daß die Kupplung wahlweise mit oder ohne Diode betrieben werden kann.The arrangement can also only be used for through-connection of the two optical fibers 4 and 14 are used when the strip line 11, 12 eo is formed that Instead of the diode 1, one correspondingly dimensioned for the connection of the two fibers There is a recess so that the coupling can be operated with or without a diode can be.
