ABSTRACT:
A link establishing system according to the present invention is constituted by connecting between an upper device and a lower device a pair of optical transmission devices which have the same configuration and are connected with each other through an optical fiber. The optical transmission device is provided with an optical signal/electric signal converting circuit for determining an optical signal transmitted from a remote device as a receive signal, an optical signal detecting circuit for outputting an optical detection signal R1 indicating a result of detecting the receive signal, a byte-synchronous circuit for detecting a synchronous pattern from the receive signal and achieving byte-synchronism to output a synchronism establishment signal C1, and a link detecting circuit for detecting link establishment to output a link establishment signal L1 based on the signals R1 and C1. A monitoring circuit outputs a link establishment informing signal LX to a upper device and a lower device when the link establishment signals L1 and L2 are detected from the both optical transmission devices.
