    摘要： A photonic-based distributed network switch and method where the switch is designed to reduce or filter optical data frames entering a port of the switch so that only data frames that are appropriate for the port are forwarded from the port. This reduces the amount of data that needs to be handled by the port interface, which is especially important where the port may be using legacy interface technology that may be incapable of handling the volume of data entering the port.

    摘要： A passive optical network is provided that spectrally slices optical signals transmitted in both upstream and downstream directions utilizing wavelength division multiplexing routing. The passive optical network preferably includes a broadband optical signal source at both ends to provide signals that are spectrally sliced according to optical frequency. The downstream information may be transmitted in a conventional data format. The upstream transmissions may be segregated by subcarrier multiplexing, time scheduling or wavelength division multiplexing. At the subscriber end of the network there is an optical network unit which includes a device coupling the downstream fiber to the upstream fiber. Such coupling allows the passive optical network to perform enhanced diagnostic tests.

    摘要： A free-space passively star-coupled optical data bus uses uniform uncollimated transmission light communicating data among a plurality of transmitter and receiver paired transceiver nodes of respective communication subsystems for communicating data from one transmitting node simultaneously to each of all of the remaining receiving nodes, the data bus being defined by a transmission volume having peripheral optical ports for optically interfacing the transceivers nodes to the free-space communication transmission medium having a distribution means to distribute the light and provide a variety of data bus configurations each supported by protocol addressing and optical modulation for connectorless communications for improved reliability and reduced costs especially well-suited for conference room, office, and spacecraft applications.

    摘要： An optical cable television system provides a large channel capacity and uses shared resources, whereby the more expensive hardware is shared over a large number of customers so as to minimize the cost per customer. A video switch network is provided which minimizes the temptation of subscribers to pirate signals since pay per view or on demand signals are provided only upon request of someone within a node corresponding to a neighborhood. An on demand program center continuously plays programs, such as movies, at time-staggered starts such that any subscriber will have only very minimal delays before seeing a particular program which is requested. A tuneable optical filter is provided in order to switch video signals onto an optical fiber going to the node in a particular neighborhood. An arrangement uses in-fiber grating in order to remove and insert different optical frequencies. Local insertion of various program sources, such as local commercials, is accomplished effectively by making such insertion at a relatively high point in the video distribution chain. An interface arrangement to provide on demand video signals to telephone company twisted pair wires is utilized.

    摘要： A self-amplified communication system or network (SANE) is disclosed in which one or more regions of an amplifying medium are optically pumped by some or all light sources in the system. The light sources serve as both signal light beam sources and as pump sources providing pump light beams for the amplifying regions. The transmission medium may be an optical fiber, or may be a free-space or planar waveguide transmission medium. The amplifying medium may be in a fiber, waveguide or bulk geometry, and may be local to a pump source, remotely located in the system, or even distributed within the transmission medium. Fixed optical paths with or without transmission of some pump light through an optical amplifier are used. Network topology configurations may be provided, such as point-to-point, star, or ring arrangements. Communication uplinks and downlinks may operate at the same or different wavelengths; and gain may be provided for uplink, downlink, or both.
