Abstract: A network tap with battery assisted and programmable failover is disclosed. The network tap includes a processing element, at least one optical-electrical transceiver, and at least one multiplexer/demultiplexer module. A backup battery provides power to the optical-electrical transceiver(s) and the multiplexer/demultiplexer module(s) but not the processing element when operating in a failover mode. The network tap is programmable to operate in a fail open mode in which traffic received from the network passes through the network tap during failover or a fail closed mode in which traffic receive from the network is blocked during failover.
