Optical path switch apparatus of optical LAN system
First Claim
1. An optical path switch apparatus for an optical LAN system, the apparatus being provided between input and output optical fiber cables and a node device, the apparatus comprising:
- a switch body including an optical member, wherein the switch body is switched selectively between a first state in which the input and output optical fiber cables are optically connected to the node device, and a second state in which the input optical fiber cable and the output optical fiber cable are optically connected to each other in such a manner as to bypass the node device.

Abstract
In an optical LAN system, an optical connector is provided between the input and output optical fiber cables and each of the node devices. The optical connector includes a movable body (a switch body) having a prism. The movable body is switched selectively between a first position (a first state) at which the input and output optical fiber cables are optically connected to the node device and a second position (a second state) in which the input optical fiber cable and the output optical fiber cable are optically connected to each other in such a manner as to bypass the node device. This arrangement suppresses a network crash by means of a relatively simple configuration.
