ABSTRACT:
In a fiber optic communication system, a multifrequency light source generates a signal having a plurality of discrete and temporally spaced wavelengths. The wavelengths can be modulated with data for transmission in an optic medium. The multifrequency light source is cascaded with a power splitter for dividing the generated signal into a plurality of multifrequency signals of substantially equal power. The wavelengths in the plurality of signals may be modulated with data for transmission in an optical medium to a temperature-sensitive router which services a plurality of optic receivers for retrieval of the data. A method is provided for communicating to a host terminal complex (HTC) that a drift in the router has occurred as a result of a change in router temperature.
