Abstract
A method and apparatus for training an optical switch include a splitter for splitting an optical signal into a plurality of reduced power optical signals, the plurality of reduced power optical signals being applied to respective input ports of the optical switch, and a plurality of output power measuring devices for measuring the optical power of the optical signals at each of a plurality of output ports of the optical switch. The method and apparatus further include a controller, for adapting operational parameters within respective communications paths of the optical switch in a manner tending to reduce the optical attenuation imparted to switched optical signals within each communications path, the optical attenuation being determined using the input and output power measuring devices.
