WAVELENGTH DIVISION MULTIPLEXED TRANSMISSION SYSTEM AND METHOD THEREOF

摘要

PURPOSE: A wavelength-division multiplexed transmission system and a method for manufacturing the same are provided to prevent data loss from unbalanced gain in photo transfer process by executing light amplification in case that gain control is completed before data channel is inputted. CONSTITUTION: A transmitting photo terminal(100) recognizes addition or deduction about several data channels, and determines several amplification gains to constitute detection channel. A receiving photo terminal(130) processes test signal output from the transmitting photo terminal(100) and photo signal output from each amplifier(110,120). The transmitting photo terminal(100) delays data channel for the time that the amplifiers(110,120) interprets and processes detection channel information.
