OPTICAL AMPLIFIER AND OPTICAL TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an optical amplifier for burst signals and an optical transmitting system constituted in simplified structures to extend a service providing distance of optical access services at lower cost. SOLUTION: The laser diode oscillating conditions are changed by inputting a part or the entire part of an optical signal to a laser diode for oscillating optical signals for gain control.
