Abstract
Optical transmission equipment includes an optical transceiver circuit that transmits and receives signal light and supervisory light, a forward Raman amplifier provided at a transmitter end of the optical transceiver circuit, a backward Raman amplifier provided at a receiver end of the optical transceiver circuit, and a processor that controls the forward Raman amplifier and the backward Raman amplifier. When a counterpart backward Raman amplifier or a counterpart forward Raman amplifier provided at an opposite side through a fiber-optic transmission line is started up, the processor turns off a power of the forward Raman amplifier or the backward Raman amplifier according to a supervisory signal received from the fiber-optic transmission line, and releases an off state of the forward Raman amplifier or the backward Raman amplifier after a predetermined period of time.
