Photonic lambda switching for satellites

Abstract:

A satellite payload system is disclosed. The satellite payload system includes a plurality of optical processing modules, each including: a module input including an optical splitter, a module output including an optical coupler, a dynamic gain equalizer, an output bank of optical filters, and an input bank of optical filters; where the plurality of optical processing modules include ring-connected optical processing modules and inter-satellite optical processing modules; and at least one optical fiber ring communicatively coupled to each of the ring-connected optical processing modules; where at least one of the ring-connected optical processing modules is configured to provide on-board signal processing of wavelengths; where a plurality of the ring-connected optical processing modules are each communicatively coupled to a respective inter-satellite optical processing module; where each inter-satellite optical processing module is configured to optically communicatively couple to a respective remote satellite via its module input and via its module output.
