Abstract
Described herein is a space based subsystem of a satellite, and methods for use therewith, for producing and transmitting an optical ISL beam to another satellite. The subsystem can include, inter alia, receiver optics, optical amplifiers, a WDM demultiplexer, beam splitters, a WDM multiplexer, and transmitter optics. The transmitter optics may be configured to receive an amplified wavelength division multiplexed optical signal and, in dependence thereon, transmit an optical ISL beam to another satellite. In certain embodiments, because RF frequencies of a wavelength division multiplexed optical signal produced by the WDM multiplexer are within a same specified RF frequency range within which the other satellite is configured to transmit RF service downlink beams, there is an elimination of any need for the other satellite to perform any frequency conversions when producing the RF service downlink beams in dependence on the optical ISL beam.
