Abstract:
1. A method of transferring a plurality of satellite signals each occupying a substantially identical, predetermined satellite transmission frequency through an optical communication network, such method comprising: 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; combining the frequency shifted satellite signal and selected frequency with a second satellite signal of the plurality of satellite signals so that the selected frequency occupies a corresponding guardband between the left and right polarization signals of the second satellite signal at the predetermined satellite transmission frequency; modulating a optical carrier with the combined signals; and transferring the modulated optical carrier to a receiver through an optical fiber; and decoding the first and second satellite signals within the receiver.
