Abstract
An L band optical amplifier in disclosed. The optical amplifier includes a signal line for transmitting a light signal in a first direction. The signal line has an input, an output disposed optically downstream of the input, and an amplifying gain medium optically disposed between the input and the output. The optical amplifier further includes a laser optically connected to the first amplifying gain medium and an apparatus for directing C band light generated in a second direction, opposite the first direction, into the amplifying gain medium.
