Abstract

An optical amplifier with first and second serially connected optical amplifier stages, each of which includes an input and an output, the second of which includes a length of amplification fiber connected to a source of pump light, a signal input connected to the input of the first amplifier stage that receives an optical signal, a reflector connected to the output of the second amplifier stage that reflects an amplified signal back through the second amplifier stage, an isolator device connected between the output of the first amplifier stage and the input of the second amplifier stage that separates incoming and outgoing amplified signals to and from said second amplifier stage, and a signal output optically connected to said isolator device. In one embodiment, the isolator device is a three-way isolator such as a circulator.
