Abstract
A system and method for selectively amplifying an optical signal depending upon the amplification needs of an optical system at one point in time. The optical amplifier has an adjustable gain that can be controlled by a remote systems controller. As a result, if an optical path in an optical system is changed, the needed degree of amplification associated with that new optical path can be provided for by adjusting the optical amplifier. The output at the end of the optical system can therefore be kept within a predetermined operational range regardless to how the optical signal is switched within the optical system.
