Abstract

PURPOSE:To easily add to an existing optical LAN system the function that an optical transmission line can bypass a terminal equipment by serially inserting the titled device into the connection part between the optical transmission line and the terminal equipment and bypassing an input signal. CONSTITUTION:An input optical signal from the transmission line directly goes to a rod lens 61c from a rod lens 61a, while an input optical signal from the terminal equipment directly goes to a rod lens 61b from a rod lens 61d. The terminal equipment is connected to an optical transmission loop. If a solenoid 64 is operated, two reflecting mirrors 63a and 63b are displaced to a position shown by dotted lines, whereby the input optical signal from the rod lens 61a is refracted bypasses the terminal equipment and is returned to the optical transmission loop from the rod lens 61b. When a device interface part 52 is inserted into the plug of the terminal equipment, ferrules 52a and 52b ensure a satisfactory connection. Thus, the titled device is inserted into the joint between the loop network of the existing optical LAN system and the terminal equipment to add a signal bypassing function.
