A small form factor pluggable ('SP') transceiver for use in a communications network includes a transmitter adapted to be coupled to the network for supplying signals to the network, a receiver adapted to be coupled to the network for receiving signals from the network, and a programmable signal processing module coupled to the transmitter and the receiver and adapted to be programmed from a remote station coupled to the network. The module can be programmed to perform at least one service or management function on the network.

In one embodiment, a connection is maintained between a pair of ethernet ports that have circuitry connected in series with the ports and receiving power-over-ethernet (PoE) from one of the ports, by providing a controllable bypass circuit coupled to the pair of ethernet ports in parallel with the circuitry receiving power-over-ethernet, sensing a preselected condition, and opening and closing the bypass circuit in response to the presence or absence of the preselected condition. Power sourcing equipment (PSE) may supply the one of the ports with power over ethernet, and the circuitry may transports data between the pair of ethernet ports. The circuitry may also supply the switch with a control signal in response to the detection of the preselected condition.
