ABSTRACT:
A bi-directional erbium doped fiber (EDF) optical fiber amplifier (50) employing two separate EDF amplifier channels (52, 62) for two counter-propagating signals allows the optimization of each individual signal channel for efficient bi-directional optical signal repeater performance. The pump sources (53, 63) for each EDF channel (52, 62) can be switched on and off independently, to serve as an in-line signal switch, without affecting another signal channel.
