ABSTRACT:
Transmission of clock signals at the pump wavelength of an optical amplifier utilized to amplify data signals being communicated in an optical network. The clock signals synchronize the data signals to a terminal utilizing the optical network. The pump wavelength is generated by a pump laser which supplies the amplification power for the optical amplifier. The clock signals are communicated on the pump optical wavelength by directly modulating the pump laser or by using an external modulator which inhibits the transmission of the pump laser's output.
