Abstract:
1. A wavelength-division multiplexed optical transmission system for transmitting an optical wavelength-division multiplexed signal using frames via an optical fiber transmitting line, comprising: a transmitter for converting an inputted electric signal into the optical wavelength-division multiplexed signal and transmitting the optical wavelength-division multiplexed signal; a receiver for receiving said transmitted optical wavelength-division multiplexed signal; a frame phase updating unit for mutually differing transmitting frame phases between at least two or more wavelength channels among a plurality of wavelength channels which are transmitted through a same optical fiber transmitting line; a frame configuration unit for configuring frames of said wavelength channels from a signal to be transmitted to said optical fiber transmitting line and selecting an output signal frame phrase itself at random; and a device for reducing mutual interference among a plurality of wavelength channel frames which are transmitted through said same optical fiber transmitting line, wherein said frame phase updating unit comprises:
