ABSTRACT:
A method, apparatus and system for controlling power transients in a Raman-amplified optical transmission system includes, in response to the detection of a power transient in an optical signal, varying the gain of at least one dispersion compensating module (DCM) in the Raman-amplified optical transmission system to correct for a change in signal power caused by the power transient.
