Abstract
Optical amplifiers and other optical network equipment are provided for use in fiber-optic communications networks. The equipment may include dynamic spectral filters and optical channel monitors. Control units may be used to control the operation of the equipment. Components in the equipment may be interconnected using communications paths. The communications paths may include paths such as synchronous and asynchronous paths, point-to-point and multidrop paths, RS-232 paths, two-wire interface bus paths, parallel bus paths, and synchronous serial interface paths. The communications paths may be used to support an extensible equipment architecture that allows equipment features to be changed and added.
