【発明の詳細な説明】 〔技術分野〕 本発明は、光コネクタの切替方法に関するものである。[Detailed description of the invention] 〔Technical field〕 The present invention relates to a method for switching optical connectors.

クタを接続することにより行われる。Recently, a method of switching a section of an optical communication line from a working line to a switching line for a different route has been studied, and this line switching is performed by switching optical connectors. In other words, at the point where the optical connector is connected to the working line, after the first optical connector and the second optical connector connecting the working line are disconnected, the first optical connector (the one that remains after switching) is connected. This is done by connecting a third optical connector attached to the end of the switching line.

を行うようになっている。By the way, a normal optical connector is made by fixing an optical fiber so that the end face of the optical fiber is exposed at a predetermined position (in the case of a single fiber, at the center position), and the end face is mutually connected to the other optical connector. It is designed to be connected against the . When connecting, it is necessary to align the centers of both optical fibers accurately, so the optical connector has pin fitting holes formed in parallel on both sides of the optical fiber. The optical connectors are aligned by inserting a pin across the pin fitting hole.

限り短くすることが望まれている。Because optical connectors have such a structure, if you manually switch between connected optical connectors by disconnecting them and connecting another optical connector to one of them, it will take several seconds or more to make one switch. During this time, communication is interrupted. Currently, it is desired to shorten the communication interruption time associated with this switching as much as possible.

を特徴とするものである。The present invention provides a method for switching optical connectors that solves the problems of the prior art such as the upper string, and the method includes a first optical connector that remains after switching and a second optical connector that is removed by switching. In the method for switching an optical connector, the method switches from a state in which the optical connector is connected to a state in which the first optical connector and a third optical connector for switching are connected to each other by disconnecting the connection, After placing the optical connector in parallel with the second optical connector with their end faces aligned, push the pin inserted across the first and second optical connectors from the second optical connector side to connect the first optical connector. The end of the pin is made to protrude from the rear end of the optical connector, the protruding end of the pin is grasped and the pin is pulled out until it comes out of the second optical connector, and then the second and third optical connectors are moved simultaneously. After the first and third optical connectors are butted against each other, the pin is pushed in so that it straddles the first and third optical connectors.

ることができる。In this way, when the pin is pulled out, the connection between the first and second optical connectors is released, and when the second and third optical connectors are moved laterally, the first and third optical connectors are butted against each other, and the pin is pushed in. Since the first and third optical connectors are connected,
It becomes possible to switch optical connectors in an extremely short period of time, and the current pins can be used as they are even after switching.
