APPARATUS AND METHOD FOR COMPENSATING TRANSMISSION CHARACTERISTIC OF OPTICAL DEMULTIPLEXER/OPTICAL MULTIPLEXER

摘要

PROBLEM TO BE SOLVED: To provide a compensation apparatus for compensating the accumulated gradient of transmission characteristics of an optical demultiplexer/optical multiplexer in a wavelength multiplex optical communication system.

SOLUTION: The compensation apparatus includes optical components having a transmission characteristic for totally compensating the accumulated gradient of the transmission characteristics in a signal wavelength band of optical signals for a plurality of channels configuring the wavelength multiplex light in the wavelength dependence of the transmission characteristics for a plurality of sets of the optical demultiplexers/optical multiplexers.
