    摘要: An optical amplifier includes at least one amplification stage having a saturation recovery time of less than one (1) millisecond. The amplification stage includes a gain medium operable to receive at least one pump signal and to receive from a multiple span communication link an optical signal comprising a leading edge. The at least one pump signal and the optical signal travel in the same direction at approximately the same speed through at least a portion of the gain medium. In one particular embodiment the leading edge of the optical signal after passing through a plurality of amplifiers when received by a receiver coupled to the communication link comprises a peak power that is no more than ten times the average power of the optical signal at the receiver.
