Abstract

PURPOSE:To shorten the time for changing over and to prevent flawing of the end faces of optical connectors by constituting a device in such a manner that the changing over of the optical connectors is executed by a slight retreat and lateral movement and slight advance of the 2nd and 3rd or 1st connector. CONSTITUTION:The 2nd and 3rd optical connectors are just disposed in parallel, then both are simultaneously retreated by an actuator 32 to provide a slight spacing between the 1st and 2nd optical connectors at the time of changing over the connection state of the 1st and 2nd optical connectors 11A, 11B to the connection state of the 1st and 3rd optical connectors 11A, 11C. The 1st optical connector 11A is then moved in the arraying direction of the 2nd and 3rd optical connectors by as much as the distance between the same by an actuator 24. The 2nd and 3rd optical connectors are thereafter advanced to butt the 1st and 3rd optical connectors against each other. The time for the changing over is shortened and the flawing of the end faces of the optical connectors is prevented by such method.

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.

わせ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 precisely match the center axes of both optical fibers, so the optical connector has pin fitting holes formed in parallel on both sides of the optical fiber. A pin is inserted so as to straddle the opposing pin fitting holes to align the optical connectors with each other.

されている。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. It is also required to avoid damaging the end face of the optical connector during switching.

合わせること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 as described above. In the method for switching an optical connector, the method switches from a state in which the connector is connected to a state in which the first optical connector and a third optical connector for switching are connected by releasing the connection to a state in which the first optical connector and the third switching optical connector are connected. After placing the optical connector in parallel with the second optical connector, when the second and third optical connectors are placed simultaneously or the first optical connector is placed alone, a gap is created between the first and second optical connectors. Then, either the second and third optical connectors are connected simultaneously, or the first optical connector is connected alone, and the second and third optical connectors are connected in the direction in which the second and third optical connectors are lined up. The first and third optical connectors are moved by a center distance, and then the retracted optical connector is moved forward to abut the first and third optical connectors.

ることがなく、傷の発生を防止できる。In this way, the time required to switch from the connection state of the first and second optical connectors to the connection state of the first and third optical connectors is as follows:
This is the time required to slightly retract, move laterally in the direction in which the second and third optical connectors are lined up, and move only the retracted bone forward, making it possible to switch optical connectors instantly. . In addition, since the second and third (or first) optical connectors are moved back slightly before being moved laterally, the end faces of the optical connectors do not rub against each other, which prevents scratches from occurring. It can be prevented.

In the optical connector switching method, after the third optical connector is arranged in parallel with the second optical connector, the second and third optical connectors are connected simultaneously or One optical connector is moved back alone to create a gap between the first and second optical connectors, and then the second and third optical connectors are simultaneously connected, or the first optical connector is moved alone. Move the second and third optical connectors by the center distance of the second and third optical connectors in the direction in which they are lined up, and then move the retracted optical connector forward to connect the first and third optical connectors. An optical connector switching method characterized by butting connectors together. （２）切替後も残る第一の光コネクタと切替により外さ
