Abstract: Methods and systems for variable rate control include determining a new communications rate in response to measured data traffic patterns. A receive change message is transmitted to a receiver that triggers the receiver to wait for an end of transmission (EoT) message and to set a new communications rate. A transmit change message is transmitted to a transmitter that triggers the transmitter to send the EoT message to the receiver, to set the new communications rate, and to send a start of transmission (SoT) message to the receiver before resuming data communications.

Abstract: Systems and methods for method for data transport using secure reconfigurable branching units, including receiving signals from a first trunk terminal and a second trunk terminal by branching units. Broadcasting is prevented for secure information delivery by dividing, within the branching units, the one or more signals from the first trunk terminal and the second trunk terminal into two or more sections, and sending the two or more sections to an optical coupler. Signals may be received from a branch terminal by one or more branching units using two fiber pairs, and the signals from the branch terminals may be divided into two or more groups of optical sections, wherein one of the sections includes dummy light. The divided signals from the first trunk terminal, the second trunk terminal, and dummy light from the branch terminal may be merged, and the merged signal sent to the branch terminal.

Abstract: Methods and systems for flexible-client, flexible-link optical transponders include electrical-to-optical transponders, which accept client data from a flow distributor, and a first multiplexing switch that connects modulated optical carriers from the transponders to line interfaces. The electrical-to-optical transponders each include a flexible optical transport unit (OTU) framer module that compresses multiple optical data units (ODUs) into a single ODU having a higher order than any of the input ODUs to form an optical transport network (OTN) frame. An electrical-to-optical modulator modulates OTN frames onto a carrier. The transponder includes a second multiplexing switch that accepts optical carriers from line interfaces and optical-to-electrical transponders that accept modulated optical carriers from the second multiplexing switch. Each optical-to-electrical transponder includes a photodetector to convert the modulated optical carriers to the electrical domain and a flexible OTU framer module that decompresses received ODUs in OTN frames into multiple ODUs to form a bit stream.
