WAVELENGTH MULTIPLEX TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To be suitable for a high-density wavelength multiplex transmission (DWDM) system having a frequency comb light generating device as a transmission source, and to detect a signal component in an error-free state on a reception side even when wavelength multiplexity is high density.

SOLUTION: A transmission section (frequency comb batch light source 11) has a frequency comb light generating source 111 and a modulator 113 for carrying a signal on carrier light by using as the carrier light a component other than two components functioning as pilot light among comb light components that the frequency comb light generating source generates, and the reception side includes a frequency comb light generating source for detection (local frequency comb generator 157) driven with a beat signal generated by multiplexing pilot light included in frequency comb light from an optical transmission line and photoelectrically converting the pilot light, and a receiver 17 which detects signal light wavelength-multiplex transmitted with frequency comb light generated by the frequency comb light generating source for detection.
