    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 signals from the first trunk terminal and the second trunk terminal into three or more sections. Signals may be received from a branch terminal by one or more branching units using a single branch fiber pair, and the signals from the branch terminals may be divided into three or more groups of optical channels, wherein at least e of the channels 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 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: An open path optical sensing system having an ultrasonic cleaner. The system includes at least one ultrasound transducer which is configured to propagate ultrasonic waves across exposed surfaces of optical components of the optical sensing system. The ultrasonic waves create tiny vibrations on the exposed surfaces of the optical components which clean the surfaces of environmental pollutants and prevent environmental pollutants from accumulating on the surface. The ultrasonic waves may have a frequency that is substantially different than the modulation frequency of a modulated laser light beam that is generated by a laser of the open path optical sensing system. The surfaces of a plurality of optical components may be cleaned by the ultrasonic waves of a single ultrasound transducer. A plurality of ultrasound transducers may propagate waves on a single optical component.
