Abstract: A single fiber transceiver is for use in a node of a single fiber network. The transceiver repeats signals received from one node to the next node. The node may have a processor, such as a sensor or controller, connected to the transceiver for receiving signals from the network or transmitting signals onto the network. The transceiver has a receiver and associated receive data path logic and has a transmitter and associated transmission data path logic. It also has a jam detection circuit, a pulse width compensation circuit, a phase locked loop, a weak link detection circuit and an anti-recirculation timer. The jam detection circuit cuts off nodes that transmit overly long packets to prevent the remainder of the network from becoming jammed. Before a received pulse is repeated, the pulse width compensation circuit reconstitutes each data pulse from the leading edge of the pulse in order to limit degradation of the signal as it is transmitted about the network.
