Abstract: In certain embodiments, a communication network has a specialized ingress node that converts one or more incoming flows into a single, packetized, time-division multiplexed (TDM) flow; a switch fabric that routes the TDM flow via a fixed path through the switch fabric in a contention-free manner; and a specialized egress node that converts the TDM flow received from the switch fabric into one or more outgoing flows corresponding to the one or more incoming flows. The technology turns legacy, best-effort packet-switching into deterministic circuit-switching for a programmable selection of flows with minimal impact on network dynamics and at relatively low cost.

Abstract: Apparatus and methods are provided for transmitting and/or for receiving data over a free-space optical link. An optical data transmitter generates duplicate digital data streams carrying a same digital data sequence with a relative temporal offset and mixes them onto two different polarization channels according to a preselected linear mixing rule. An optical data receiver demodulates first and second digital streams from the two polarization channels and unmixes the demodulated data, to produce first and second output digital data streams according to a preselected linear unmixing rule. The receiver applies a quality indicator to select between segments of the respective output digital data streams that correspond to the same transmitted data sequence.
