Abstract
An optical transmission apparatus in an optical transmission system that transmits an optical signal through a transmission fiber includes a measurement device that measures Raman gain efficiency of the transmission fiber; a level determiner that determines an input level of the optical signal based on Raman gain efficiency measured by the measurement device; and a controller that controls a level of the optical signal input to the transmission fiber to become the input level determined by the level determiner.
