Abstract
Optical network equipment is provided. The optical network equipment may include equipment with optical gain stages such as optical amplifiers. The equipment may be used in fiber-optic communications links in communications networks. The gain stages may be based on optically-pumped rare-earth-doped fiber. The equipment may include optical monitors that are used to measure the power of optical data signals propagating through the equipment. A control unit in the equipment may be used to analyze the optical data signal power measurements. The results of the analysis may allow the control unit to determine whether the amplifier output power is affected by gain transients or drift effects. Gain transients may be suppressed by making pump power adjustments. The control unit may compensate for the effects of drift by making pump power adjustments or by adjusting components such as variable optical attenuators or dynamic filters.
