摘要
An optical transmitter for sending supervisory data signals and line data signals as a composite optical signal through an optical fiber link is disclosed. The transmitter may take the form of a transmitter, transceiver or transponder and includes circuitry for receiving incoming line data bit rate information for varying and or controlling the modulation index by varying the supervisory carrier frequency amplitude in dependence upon the line data bit rate.
