    摘要: This invention provides a new architecture for a communication system between head-ends and end-users which expands bandwidth and reliability of the communication system. A mux-node receives communication signals from a head-end and forwards the received communication signals to one or more mini-fiber nodes. The connection to the head-end is via a small number of optical fibers and the connections to each of the mini-fiber nodes may be via one or more optical fibers that may provide full duplex communication. The head-end may communicate with the mux-node using digital or digital and analog signals. The mini-fiber nodes may combine the signals received from the head-end with loop-back signals used for local media access control prior to forwarding the signals to the end-users. Upstream data are received by the mini-fiber nodes and transmitted to the mux-node. The mux-node may route upstream communication signals received from the mini-fiber nodes as downstream signals to other mini-fiber nodes also connected to the mux-node without head-end interaction.

    摘要: A monitoring apparatus and method are provided for a communication system in which a central office communicates to at least one end unit using intermediate remote nodes. The remote node receives signals from both the central office and the end units. Each remote node can be equipped with apparatus for monitoring the integrity of paths of the communication system. The monitoring apparatus can include a mixing device that mixes received signals to produce combined signals. The received signals generally include a pilot signal sent from the central office and a data signal sent from the at least one end unit. The state of the communication system is analyzed based on the combined signals. If the combined signals includes only the data signal from the end unit, the path through which the pilot signal was sent is inoperative. If the combined signals includes only the pilot signal, the transmission path from the end unit over which the data signal is sent is inoperative. If the combined signals are not received at the central office after transmission of the pilot signal, a determination is made that any part of transmission path could be inoperative.

    摘要: This invention provides a method and apparatus for allocating pools of resources of a communication system to nodes and end users serviced by the nodes. The nodes are coupled to a communications network through interface units. The interface units are organized as a pool and may be either preassigned to each of the nodes or may be dynamically allocated to the nodes based on end user requests. All the nodes of the communication system uses a common frequency band. Each of the nodes is coupled to the communication network through a dedicated channel. Thus, bandwidth available to the end users are greatly expanded without expensive and complex upgrades to existing equipment.

    摘要: A laser bias preconditioning methodology is provided, and an implementation of that methodology, that improves the carrier-to-noise ratio of analog CATV signals sent over an optical transmission medium. The bias preconditioning methodology causes the laser bias current to be continuously varied to track an envelope of the carrier signal.
