The preferred embodiments of the present invention include an optical splitter module having connectorized pigtails that are stored on the bulkhead faceplate of the module. The module includes an optical splitter output harness, for example, a ribbon cable assembly attached to the bulkhead with rugged strain relief mechanism. The ribbon harness is converted to individual pigtails with connectors which are stored on adapter receptacles on the faceplate. Adapter receptacles used may optionally be half receptacles when storage is the only desired function or may be full receptacles when access to the pigtail ferrule tip is required. Access to the ferrule tip may be required for attaching fiber optic terminators to eliminate undesirable reflections caused by unterminated connectors. The module provides an administrative location for splitter outputs prior to being connected individually into service. The module also provides an administrative storage location for splitter outputs taken out of service as a temporary staging area before being reassigned and connected individually into service again.

A repeater and method provides a technique to minimize congestion and packet loss, which may be generated when a fault is detected in a ring type packet network or when the network recovers from such a fault. A repeater having a plurality of ports for transmitting and receiving packets in a ring type network for transmitting the received packets on the basis of an address included in a received packet and a transmitting port database indicating an identifier of a port to transmit the packet having the address as the destination, comprises a control packet processing block to detect reception of a fault notifying packet transmitted from a repeater having detected a fault and a control block to update, upon reception of the fault notifying packet from an immediately adjacent repeater, a port identifier of the transmitting port database having a port identifier of the port having received said fault notifying packet into a port identifier of a port connected to another immediately adjacent repeater.

The present invention comprises a system and method for communicating with a traffic signal by which at least one communication controller and integrated light controller are coupled by a high frequency (“HF”) coupler to a power line for transmission. In each of the directions of communication, specific transmission methods and data protocols are used over the communication link. The communication link protocol used for communication between the integrated light controller and the communication controller provides a robust method for framing data within a message structure that provides byte-by-byte synchronization and message integrity through a parity check per byte, and a checksum calculation.

A self-interference canceller (SIC) is incorporated into a transceiver to reduce or eliminate modem jamming when a transmitter in the transceiver transmits at high power levels. The SIC is configured to receive at a first input a transmitter noise reference signal including a self-interfering signal component generated by the transmitter, to receive at a second input a corrupted signal including the self-interfering signal component and a desired signal component generated by the transmitter, and to output a correction signal that resembles the self-interfering signal component. The correction signal is subtracted from the corrupted signal to generate a processed signal that is input to the modem. The SIC may be disabled when the output power of the transmitter is at a level below a predetermined threshold. The invention may be applied to a multi-radio access technology (RAT) transceiver.
