Abstract
An Er-doped optical fiber amplifier is adapted to increase the length of transmission path by raising the intensity of pumped light. In an Er-doped optical fiber amplifier 1 for amplifying signal light by means of an Er-doped optical fiber 7, using a 1,530 nm band pumping source 8, 1,530 nm band pumped light is Raman-amplified by a 1,430 nm-1,450 nm band light source 9 on the transmission path of an optical fiber 5.
