摘要：
A wavelength division multiplexing transmission system that comprises an input/output terminal station for an optical signal, and an intermediate station located between the terminal stations and connected by an optical transmission line for performing wavelength division multiplexing and transmission of the optical signal, wherein the signal transmission system comprising the terminal station and the intermediate station has a redundant configuration comprising the active system and standby system, and an input/output means for the optical signal to be transmitted through the active system and the standby system is provided on both the active system and the standby system on the side of the active system of the terminal station.
