Abstract
An optical amplifier for fiber-optic communications systems is provided. The optical amplifier may have variable optical attenuators for adjusting the power on each of multiple input channels. A multiplexer may be used to combine the input channels onto a single optical path. A gain stage may be used to provide optical gain for the optical signals on the optical path. A control unit may be used to control the variable optical attenuators and the gain stage to produce a desired spectrum.
