WAVELENGTH MULTIPLEXING TRANSMISSION SYSTEM, RECEIVER, TRANSMITTER, AND ADJUSTING METHOD OF THE RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a wavelength multiplexing transmission system for reducing cross-talk among wavelengths in wavelength multiplexing transmission system and to provide a receiver applied in the wavelength multiplexing transmission system and a transmission unit used in the wavelength multiplexing transmission system, and an adjusting method of the receiver.

SOLUTION: In wavelength multiplexing transmission system, a transmission unit and a receiver are connected through an optical path. The receiver includes: a wavelength separation filter for carrying out wavelength separation on an optical wavelength multiplexed signal to output N optical signals; N optical receivers for receiving N optical signals respectively from the wavelength separation filter and generates each output signal; and a differential synthesizer for synthesizing an output from one optical receiver out of the N receivers and the sum of part of output from the N-1 optical receivers respectively.
