RADIATION POWER EQUALIZER

摘要

PROBLEM TO BE SOLVED: To provide a radiation power equalizer for an optical communication system.

SOLUTION: The invention provides a radiation power equalizer for an optical communication system, the equalizer includes: (a) an optical demultiplexer (300) for partitioning into one or more radiation components; (b) a liquid crystal cell array (310) for selectively transmitting or attenuating the one or more radiation components; (c) an optical multiplexer (330); (d) a transmitter erbium-doped fibre amplifier (70) coupled to a PIN diode detector array (120) for generating one or more corresponding component radiation power indicative signals; and (e) a control module (130).
