Abstract
An optical transmission system includes an optical transmitter that sends signal light to a transmission path, an optical receiver that receives the signal light from the transmission path, and an optical amplifier that is provided on the transmission path and that amplifies the signal light, the optical amplifier being configured to control a gain characteristic of the optical amplifier such that a power of signal light having a wavelength included within a wavelength range in which polarization hole burning occurs is higher than a power of another signal light having a wavelength outside the wavelength range.
