Abstract: Disclosed is a network communication switch that facilitates reliable communication of high priority traffic over lower priority traffic across all ingress and egress ports. The network communication switch may monitor the frame storage buffer regardless of egress port, and when the frame storage buffer reaches a predetermined level, the switch may discard lower priority frames from the most congested port. When the frame storage buffer reaches a second predetermined level, the switch may discard lower priority frames before they are stored according to egress port. The network communication switch may further monitor ingress frames for priority, and assign priority to frames according to pre-assigned priority, ingress port, and/or frame contents.

Abstract: The present disclosure pertains to systems and methods for low-power optical transceivers. In one embodiment, a low-power optical transceiver may include a microcontroller and an optical receiver and an optical transmitter in communication with and controlled by the microcontroller. The optical receiver may include a photodetector configured to receive a first optical representation of a first signal to be received and to generate an electrical representation of the first signal. An amplifier may amplify the electrical representation of the first signal, and an output in electrical communication with the amplifier may generate an electrical output. The optical transmitter may include a laser diode configured to generate a second optical representation of a second signal to be transmitted. The microcontroller may be configured to control an output power of the laser diode.

Abstract: The present disclosure pertains to systems and methods to selectively interrupt a communication link. In one embodiment, a system may comprise a first communication port and a second communication port, each of which comprises a plurality of differential pairs of electrical wires. A control select circuit may be in communication with the first communication port and the second communication port and may comprise a plurality of solid-state switches operable to transition between a first configuration and a second configuration. In the first configuration the differential pairs of electrical wires are electrically connected to corresponding differential pairs of electrical wires in the second communication port. In the second configuration, the differential pairs of wires are shunted through a resistor to dissipate energy associated with an electrical signal. A control port may be operable to cause the plurality of solid-state switches to transition between the first configuration and the second configuration.
