Claim:
1. A system for delivering cable television (CATV) content between a head end and a node over a fiber optic network, said method comprising: (a) a first transmitter for generating an analog first signal comprising CATV content; (b) a second transmitter for generating a digital second signal comprising a series of digital codewords each representing an instantaneous power level of a radio frequency (RF) spectrum input to the second transmitter, wherein the RF spectrum is a composite RF spectrum comprising a combination of CATV content and the instantaneous power levels are power levels of the composite RF spectrum at intervals of a conversion clock; (c) a combiner configured to combine each of the analog first signal and the digital second signal for transmission over a same fiber extending to at least one node, wherein the first signal is transmitted at a first optical wavelength and the second signal is transmitted a second optical wavelength that is different than the first optical wavelength; and (d) at least one receiver in said transmission network at a location remote from said transmitters, that receives said analog first signal and said digital second signal, converts each of said first signal and said second signal into respective RF spectrums, combines the RF spectrums, and delivers said combined CATV content represented by said first signal and said second signal to at least one user.
