Abstract: PROBLEM TO BE SOLVED: To warrant reliable service in a large capacity optical fiber network by selecting a response time required for dynamic gain control of an optical amplifier so as to be inversely proportional substantially to the number of optical amplifiers in a communication path. SOLUTION: An erbium doped fiber amplifier 16 is one of chains in existence along a communication link. λ1 ... λn depict wavelength multiplex a plurality of channels. A check and control signal λ0 generated from a laser light source 20 and passing through a saturation absorbing body 26 is fed to the amplifier 16 via a 3-port optical circulator 22 and photocoupler pairs 24, 25.
