Abstract
An optical transmitter module includes an optical transmitter configured to emit a first optical signal that includes a user data signal having a first frequency and comprising user data associated with the first communication channel. A management diagnostic modulator can superimpose a diagnostic waveform to the user data signal. The diagnostic waveform has a second frequency associated with the first communication channel, wherein the second frequency is in a frequency range between about 10 KHz and about 10 MHz. A management unit can modulate the diagnostic waveform by a management data signal at a third frequency associated with the first communication channel. The management data signal includes management data for digital diagnostic monitoring signals (DDM) and the control of the first optical transceiver module.
