US Patent 11489613 Out-of-band communication channel for subcarrier-based optical communication systems

An example system includes a hub transceiver, a plurality of edge transceivers, and a control module. The control module is operable to receive, from one or more of the edge transceivers or the hub transceiver, telemetry data regarding at least one of a transmission or a receipt of data over the optical communications network, and determine, based on the telemetry data, performance characteristics regarding the optical communications network. Further, the control module is operable to transmit, based on the performance characteristics, a command to one or more of the edge transceivers or the hub transceiver to modify an operation with respect to the optical communications network.
