Abstract

The adjustment device consists of two pillow blocks (2, 3). The pillow blocks are movable relative to each other, and each pillow block is adapted for holding a light conducting fibre (5/7, 6/8) so that their surfaces are facing each other. The relative positions of the two optical fibres are adjustable so that the ends may be brought into axial alignment. The ends of the optical fibres are made visible by an optical system (11) which can be swung between the two pillow blocks.

Description

Justiervorrichtung für Lichtleitfasern Adjustment device for optical fibers

Die vorliegende Erfindung befaßt sich mit einer optischen Justiervorrichtung zum axialen Einrichten zweier Lichtleitfasern. Die zur Übertragung von Licht als Träger hochfrequenter Signale verwendeten Lichtleitfasern sind an Trennstellen miteinander verbunden. Eine solche Verbindung ist so auszuführen, daß an dieser Verbindungsstelle die Verluste an Übertragungsenergie sehr klein gehalten werden. Das erreicht man nur dadurch, daß einmal die Stirnflächen der Glasfaserenden genau parallel geschnitten sind und die Verbindungsstelle der mehr oder weniger axial versetzten Lichtleitfasern zwischen den beiden Faserkernen keinen axialen Versatz aufweist. The present invention is concerned with an optical alignment device for the axial alignment of two optical fibers. Those used to transmit light as Optical fibers used to carry high-frequency signals are at separation points with one another tied together. Such a connection is to be carried out in such a way that at this connection point the losses of transmission energy can be kept very small. You can achieve that only by the fact that once the end faces of the fiberglass ends are cut exactly parallel and the connection point of the more or less axially offset optical fibers has no axial offset between the two fiber cores.

Diese Bedingung zu erfüllen, besteht in der Aufgabenstellung der vorliegenden Erfindung. Es ist ein Justiergerät zu schaffen, das die beiden Längsachsen der Lichtleitfaserkerne genau zur Deckung bringt und einen axialen Versatz ausschließt. Fulfilling this condition consists of the task at hand the present invention. An adjustment device is to be created that covers the two longitudinal axes which brings the optical fiber cores exactly into congruence and excludes an axial misalignment.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Justiervorrichtung aus zwei gegeneinander bewegbaren Lagerböcken besteht, in denen je eine mit ihren Stirnflächen aufeinander gerichtete Lichtleitfaser gehalten und in ihrer Lage zueinander justierbar sind und daß eine auf beide Stirnflächen gerichtete und zwischen den Lagerböcken aus- und einschwenkbare Optik die Lage der Stirnflächen und der sichtbar gemachten Lichtleitfaserkerne zueinander erkennbar macht, wobei mindestens ein Lagerbock eine Justiereinrichtung hat, die die axiale Lage der Lichtleitfaser in zwei aufeinander senkrecht stehenden Richtungen veränderbar macht.According to the invention this object is achieved in that the adjusting device consists of two mutually movable bearing blocks, in each of which one with their End faces directed towards each other optical fiber held and in their position to each other are adjustable and that one directed to both end faces and between the Bearing blocks which can be swiveled out and in, the position of the end faces and the visible made optical fiber cores to each other makes recognizable, with at least one bearing block has an adjusting device which the axial position of the optical fiber in two on top of each other makes perpendicular directions changeable.

Diese Anordnung stellt eine sehr einfache Handhabung dar, die eine optimale, axiale Justierung der beiden aneinanderstoßenden Stirnflächen der Lichtleitfaserkerne gewährleistet.This arrangement represents a very simple handling, the one optimal, axial adjustment of the two abutting end faces of the fiber optic cores guaranteed.

Anhand der Zeichnung wird die Erfindung noch näher beschrieben. Die einzelnen Figuren stellen dar: Die Fig. 1 eine Ansicht der Justiervorrichtung von vorn mit eingeschBenkter Optik, die Fig. 2 die Ansicht der Justiervorrichtung von der Seite mit eingescllwenkter Optilc, die Fig. 3 die Ansicht der Justiervorrichtung von vorn mit ausgeschwenkter Optik, die Fig. 4 die Ansicht der Justiervorrichtung von der Seite mit ausgeschwenkter Optik, die Fig. 5 eine Verbundstelle zweier Lichtleitfasern in einer Ansicht von der Seite uiid die Fig. 6 einen Schnitt durch eine Lichtleitfaser mit sichtbar gemachtem, axial versetztem Eiern.The invention is described in more detail with reference to the drawing. the individual figures show: FIG. 1 is a view of the adjusting device from FIG front with inserted optics, FIG. 2 the view of the adjusting device from the side with the optic pivoted in, FIG. 3 the view of the adjusting device from the front with the optics pivoted out, FIG. 4 shows the view of the adjusting device from the side with the optics pivoted out, FIG. 5 shows a connection point of two optical fibers in a view from the side and FIG. 6 a section through an optical fiber with axially offset eggs made visible.

Die in der Fig. 1 dargestellte Justiervorrichtung in einer Ansicht von vorn besteht aus einer Grundplatte 1, auf der die beiden gegeneinander bewegbaren Lagerblöcke 2 und 3 in einer Führung (nicht dargestellt) gelagert sind. Der Lagerbock 2 ist bei diesem Ausführungsbeispiel auf der Grundplatte 1 fest montiert, während der Lagerbock 3 mittels eines Drehknopfes 4 in horizontaler Richtung bewegbar und arretierbar ist.The adjusting device shown in Fig. 1 in a view from the front consists of a base plate 1 on which the two can be moved against each other Bearing blocks 2 and 3 are stored in a guide (not shown). The bearing block 2 is fixedly mounted in this embodiment on the base plate 1, while the bearing block 3 can be moved in the horizontal direction by means of a rotary knob 4 and is lockable.

Diese beiden Lagerböcke 2 und 3 nehmen je eine mit je einem Spleißteil 5 und 6 versehene Lichtleitfaser 7 und 8 in einer Führung auf und werden jeweils in ihrem Lagerbock 2 und 3 in ihrer Lage gehalten.These two bearing blocks 2 and 3 each take one with a splice part each 5 and 6 provided optical fiber 7 and 8 in a guide and are respectively held in their bearing block 2 and 3 in their position.

Jede Lichtleitfaser 7 ulid 8 wird in ihrer Halterung von je einer Lichtquelle 9 und 10 von der Seite her dllrchh eine Öffnung des Spleißteiles beleuchtet, wobei das Licht durch den Außenmante 1 der LichtleitfaseXrll 7 und 8 eindringt. Die Stirnflcichen zeigen bei diesel seitlichen Beleuchtung einen dunklen, axial versetzten Lichtleitfaserkern 14 und einen hell erleuchteten Lichtleitfasermantel.Each optical fiber 7 ulid 8 is in its holder of one Light source 9 and 10 illuminates an opening of the splice part from the side, whereby the light penetrates through the outer jacket 1 of the optical fiber Xrll 7 and 8. The front surfaces show a dark, axial light with this lateral illumination offset fiber optic core 14 and a brightly lit fiber optic cladding.

Die Entfernung der beiden Lagerböcke 2 und 3 voneillander ist so bemessen, daß eine an der Grundplatte 1 spielfrei schwenkbar befestigte Optik 11 zwischen die beiden Lagerböcke 2 und 3 mit ihren Lichtleitfasern zwischenpaßt (Bewegung in Richtung A).The distance between the two bearing blocks 2 and 3 from one another is such that that an optics 11 which is pivotably attached to the base plate 1 and is free of play between the two bearing blocks 2 and 3 with their optical fibers between fits (movement in Direction A).

Diese Optik 11 ist so ausgebildet, daß die beiden Stirnflächen der Lichtleitfasern 7 und 8 sichtbar sind und die Lichtleitfaserkerne 14 genau miteinander zur Deckung gebracht werden können.This optics 11 is designed so that the two end faces of the Optical fibers 7 and 8 are visible and the optical fiber cores 14 exactly with one another can be brought to congruence.

Diese Einstellung zur gemeinsamen Deckung der beiden Spleißteile 5 und 6 erreicht man durch zwei voneinander senkrecht stehende Justierschrauben 12 und 13. Sind beide Lichtleitfaserkerne 14 miteinander zur Deckung gebracht, so wird die Optik 11 wieder in ihre Ausgangslage zurwickgeschwenkt (Richtung G) und der Lagerbock 3 gegen den Lagerbock 2 geschoben, bis die beiden Spleißteile 5 und 6 aufeinanderstoßen.This setting for the joint coverage of the two splice parts 5 and 6 is reached by two of each other vertical adjusting screws 12 and 13. If both optical fiber cores 14 are brought into congruence with one another, so the optics 11 is swiveled back into its starting position (direction G) and the bracket 3 is pushed against the bracket 2 until the two splice parts 5 and 6 clash.

Diese Lage ist in der. Fig. 3 wiedergegeben. Die beiden Spleißteile 5 und 6 stoßen aufeinander und die Optik 11 ist zurückgeklappt.This situation is in the. Fig. 3 reproduced. The two splice parts 5 and 6 collide and the optic 11 is folded back.

Die Fig. 4 zeigt die Justiervorrichtung mit zurückgeklappter Optik 11 entsprechend der Fig. 3, jedoch in einer Ansicht von der Seite. Die Positionsbezeichnungen entsprechen denen in der Fig. 1.4 shows the adjusting device with the optics folded back 11 corresponding to FIG. 3, but in a view from the side. The item names correspond to those in FIG. 1.

Die beiden Spleißteile 5 und 6 werden nach ihrem Zusammenstoßen durch Verkleben oder Verschweißen fest miteiiiander verbunden. Zwei miteinander verbundene Spleißteile 5 uiid 6 mit ihren Lichtleitfasern 7 und 8 zeigt die Fig. 5 in einer Ansicht von der Seite.The two splice parts 5 and 6 are through after they meet Gluing or welding firmly connected to one another.
