摘要
PURPOSE: A wide band fiber amplifier for amplifying a C-band optical signal and an L-band optical signal is provided to obtain the high amplification efficiency by pumping an amplification fiber for amplifying only L-band optical signals by spontaneous emission light. CONSTITUTION: A first amplifier(270) includes a first amplification fiber for amplifying a C-band optical signal and an L-band optical signal received from an external fiber(210) and outputting spontaneous emission light. An L-band pump light source(280) includes is pumped by the spontaneous emission light and includes a third amplification fiber for outputting the amplified spontaneous emission light. A second amplifier(290) includes a second amplification fiber for amplifying the amplified L-band optical signal. The amplified C-band signal and the secondary amplified L-band optical signal are outputted to the external fiber.
