Abstract
Disclosed is a gain-controllable wideband optical fiber amplifier for amplifying both C-band and L-band optical signals, which comprises: a first amplifying section configured to (1) be pumped in at least one direction, (2) amplify both C-band and L-band optical signals and (3) output an amplified spontaneous emission; an optical attenuator for attenuating the power of the spontaneous emission; and a second amplifying section pumped by the attenuated spontaneous emission to secondarily amplify the amplified L-band optical signals.
