Abstract
Provided are an optical communication apparatus, an optical communication method, and an optical communication system that each can improve transmission characteristics. An optical communication apparatus includes a monitor unit configured to, when the optical communication apparatus connects to an optical communication network and converts an optical signal received from another optical communication apparatus to a digital signal, monitor a reception waveform of the optical signal, the optical communication network including a plurality of optical communication apparatuses connected via a transmission line that transmits WDM signal light in which a plurality of optical signals are wavelength-division multiplexed; and a center wavelength controlling unit configured to, based on the monitored reception waveform, feedback-control a center wavelength of a transmission waveform of an optical signal that the other optical communication apparatus transmits.
