POST-TRANSIENT GAIN CONTROL OF OPTICAL AMPLIFIERS

摘要

Methods and systems for post-transient gain control of optical amplifiers may include using a gain offset control module in an optical amplifier to generate a gain offset cancelling signal. The gain offset cancelling signal may be output to a gain control module in the optical amplifier to generate at least one of a pump signal and an attenuation control signal. In this manner, a gain offset may be cancelled for a plurality of wavelengths in an optical signal transmitted by an optical network.

1. A method for post-transient gain control of an optical amplifier, comprising:
receiving an optical signal having a plurality of wavelengths; generating a pump signal for a doped fiber amplification element; multiplexing the optical signal and the pump signal into the doped fiber amplification element; generating a gain offset cancelling signal; and using the gain offset cancelling signal to generate the pump signal, wherein a gain offset is cancelled for the plurality of wavelengths in the optical signal output from the optical amplifier.
