Abstract: Presented herein are techniques for preventing an electrical arc upon disconnect of a network cable. A method can include monitoring a network cable connected to a device for faults at a remote location from a connector of the network cable by observing conditions on the network cable of power applied to the network cable, wherein the network cable is for sending data and power. The method can further include detecting a fault on the network cable, wherein the fault was introduced intentionally at the connector prior to disconnecting the connector from the device. The method can further include terminating power at the remote location that is sent over the network cable to prevent an electrical arc upon disconnecting the connector from the device.

Abstract: In one embodiment, a method includes applying Forward Error Correction (FEC) to data at power sourcing equipment, transmitting the data and pulse power over a wire pair to a powered device, identifying data transmitted during power transitions between a pulse power on time and a pulse power off time in the pulse power at the powered device, and applying FEC decoding to at least a portion of the data based on said identified power transitions.

Abstract: In one embodiment, a method includes transmitting pulse power on two wire pairs, the pulse power comprising a plurality of high voltage pulses with the high voltage pulses on the wire pairs offset between the wire pairs to provide continuous power, performing low voltage fault detection on each of the wire pairs between the high voltage pulses, and transmitting data on at least one of the wire pairs during transmittal of the high voltage pulses. Data transmittal is suspended during the low voltage fault detection.

Abstract: Presented herein are techniques for connectors, apparatuses, and system with connectors for data and power. A connector at an end of the network cable can be configured to mate with a port in a device. The connector can include a set of data pins for connecting data wires in the network cable to the port. The connector can include a set of power pins for connecting power wires in the network cable to the port. The set of power pins can carry a higher electrical power than that carried by the set of data pins. A first spacing between adjacent power pins in the set of power pins has at least a minimum distance to reduce voltage breakdown between the adjacent power pins in the set of power pin.
