摘要： A hollow core fiber (HCF) link is characterized by structural properties selected to support and sustain light propagation in a fundamental mode and in at least one higher-order mode. Connected to a proximal end of the HCF link, there is a mode coupler configured to couple a data signal into the fundamental mode and to couple an obfuscating signal into the at least one higher-order mode for simultaneous propagation of the data signal and the obfuscating signal on the HCF link, where the obfuscating signal substantially overlaps the data signal in spectral content. At a distal end of the HCF link, there is a mode splitter configured to split a first optical signal detected in the fundamental mode from a second optical signal detected in the at least one higher-order mode.

摘要： A satellite includes a plurality of transceivers, each configured to selectively connect to one of another transceiver in another satellite and a ground station; and configurable pass-through between the plurality of transceivers that is configured based on a location of the satellite in a constellation. The configurable pass-through can provide data signal pass-through without one or more of full decoding, regeneration, and error correction, thereby saving power.
