Patent ID: 8009988

Claim:
A method of reducing crosstalk and associated distortion in multiplexed optical signals comprising: receiving a plurality of radio frequency (RF) signals, some of which are broadcast; converting the plurality of RF signals into a plurality of intensity-modulated optical signals, wherein each of said plurality of intensity-modulated optical signals has a different wavelength, forming one or more pairs of intensity-modulated optical signals by selecting for each pair a first intensity modulated signal that is inverted to a second intensity modulated optical signal, wherein the intensity modulated optical signals that comprise each pair are chosen from the plurality of intensity modulated optical signals and are relatively close in wavelength but not the same; multiplexing the one or more pairs of intensity-modulated optical signals into a multiplexed optical signal; and transmitting the multiplexed optical signal through a fiber optic network, wherein the inverted pairs of intensity modulated optical signals reduce crosstalk and associated distortion imposed on any other optical signal that comprises the multiplexed optical signal by any one of the intensity modulated optical signals that form the pairs.
