摘要： A supervisory system in a wavelength division multiplexing communications network is provided with a first and a second terminal stations and a repeater unit. The first terminal station transmits a supervisory signal to the second terminal station. The second terminal station transfers the supervisory signal to the repeater unit to be monitored. Paths to a hub station A and a hub station B can be a single path by looping back a supervisory signal output from the hub stations A and B for issuing and terminating the supervisory signal at a first and a second branch stations connected through an optical wavelength multiplexing/demultiplexing unit. If the hub station B loops back a supervisory signal, the supervisory signal output from the hub station A can be returned to the hub station A again after circulating the path. If the path of the supervisory signal is set to allow the signal to pass through all repeater units, only one channel is required for a supervisory signal without lowering the modulation rate during a branching operation, and the repeater unit can receive a supervisory signal without fail.

摘要： A Raman amplifier repeater comprising a Raman excitation light production/answer signal superimposition unit for producing a first reply signal for a down-direction line with respect to a monitor control command, an answer signal production unit for producing a second reply signal with respect to the monitor control command, and a command reply switch for selectively using the first reply signal when an optical signal passing through a down-direction line on a second terminal station side is inputted as an answer signal with respect to the monitor control command and the second reply signal when the optical signal is not inputted through the second terminal station side down-direction line. With this configuration, high-quality monitor control is feasible even if a disconnection/break trouble occurs in an optical fiber in conducting the optical amplification repeating by the Raman amplification.

摘要： A circulator guides wavelength multiplexed light that is received from a main transmission path to a 1st fiber grating. The 1st fiber grating reflects light of wavelength &lgr;1. Wavelength multiplexed light that has passed through the 1st fiber grating is guided to a 2nd fiber grating. The 2nd fiber grating reflects light of wavelength &lgr;n. The circulator guides the signal light that has been reflected from the 1st and 2nd fiber gratings to a branch transmission path. The length of the transmission path between the 1st and 2nd fiber gratings is determined based on the transmission rate or frequency of the signal that is transmitted using light of wavelength &lgr;n.
