ABSTRACT:
Optical energy is provided to an optical amplifier by a first and a second pump laser. The optical energy that is provided is used as a basis for generating a gain associated with the optical amplifier. An error associated with the first pump laser may be identified. One or more parameters associated with the second pump laser may be controlled in response to the error such that the second pump laser increases an optical power output provided to the optical amplifier to compensate for the full or partial failure of the first pump laser. The adjustment in optical power output is used by the optical amplifier to substantially maintain the gain associated with the optical amplifier.
