Abstract
A method and apparatus are provided for transferring a plurality of satellite signals through an optical communication network. The method includes the steps of selecting a frequency of a local oscillator signal within a guardband between a left polarization signal and a right polarization signal of a first satellite signal of the plurality of satellite signals, frequency shifting the first satellite signal upwards in frequency by the selected frequency. The method further includes the steps of combining the frequency shifted satellite signal with a second satellite signal of the plurality of satellite signals and modulating a optical carrier with the combined signals, transferring the modulated optical carrier to a receiver through an optical fiber and decoding the first and second satellite signals within the receiver.
