Abstract
A system for generating an optical CATV comb comprising a plurality of wavelength division multiplexed (WDM) optical CATV signals. A set of one or more lasers generate a plurality of narrow-band continuous wave (CW) lights, each CW light having a respective predetermined wavelength and optical power level. An optical MUX couples the plurality of CW lights into a WDM continuous wave light. A broadband optical modulator responsive to a CATV signal modulates the WDM continuous wave light to generate the optical CATV comb.
