Abstract
An optical transmitteroutputs an optical signal, and an optical booster amplifieramplifies the optical signal and sends the amplified optical signal to an optical fiberforming an optical transmission line. When detecting an optical signal fluctuation factor, an optical transmitter control partoutputs a light surge warning signalprior to an optical signal fluctuation, and a gain control partresponds to the light surge warning signalto decrease the gain of the optical booster amplifierdown to a level where no light surge occurs.
