  • Publication number: 20120131633
    Abstract: A point of distribution that distributes source information to a plurality of subscriber gateway devices through a communications network. A television broadcast spectrum is divided into a plurality of channels. Each channel has a deterministic bandwidth for transmitting packetized data, and each deterministic bandwidth is subdivided into a plurality of unshared bandwidth allocations. An unshared bandwidth allocation is allocated to each subscriber gateway device and source information is transmitted in packetized format to the subscriber gateway device based on the unshared bandwidth allocation.

  • Patent number: 8141121
    Abstract: A communication system for distributing information via a network to one or more subscribers includes a multi-port switch, one or more radio frequency (RF) modems coupled to respective ports of the switch, a combiner and a transmitter. The switch forwards source information to the RF modems based on address information. Each RF modem modulates and up converts information from the switch to an RF signal within a respective subscriber channel of the television broadcast spectrum. Each channel is assigned to one or more subscribers, and each subscriber is allocated unshared bandwidth. The combiner combines modulated information from each RF modem into a combined signal and the transmitter transmits the combined signal to the subscribers via the network. Each subscriber destination includes a gateway device or the like that is tuned to a corresponding channel to retrieve source information from that channel, and to deliver the information to the subscriber.

Each channel is assigned to one or more subscribers, and each subscriber is allocated unshared bandwidth. Each channel may be further divided into unshared bandwidth increments, so that multiple subscribers may share a single channel. The combiner combines modulated information from each RF modem into a combined signal and the transmitter transmits the combined signal to the subscribers via the network.

  • Patent number: 7362931
    Abstract: An optical conversion device for a shared FTTH distribution network including first and second optical fibers and an optical processing circuit. The optical processing circuit has an input for receiving a first optical analog signal carried by the first optical fiber and an output for providing a first optical digital signal for transmission via the second optical fiber. The optical processing circuit is configured to digitize the first optical analog signal and incorporate into the first optical digital signal. The optical analog signal may be an optical signal which is modulated by an RF signal, which is the same or similar to that of existing HFC networks. High loss electrical signals are converted to low-loss optical signals propagated within the optical plant. The combined optical analog and digital protocol supports analogous communications of existing HFC networks and the optical plant minimizes cost of fiber optic upgrade.

  • Patent number: 7266265
    Abstract: A low-loss shared FTTH distribution network that enables optical communications within a subscriber area, including optical fibers routed from a point of distribution to the subscriber area, a tap device including an optical tap which interfaces a downstream optical fiber with a first optical fiber, and a straight-through optical fiber which is routed straight through the tap device. The tap device may include a splitter which splits the downstream optical fiber into multiple downstream optical fibers, and the tap device may include tap ports for the downstream optical fibers. Any number of straight-through optical fibers may be included which are routed straight through the tap device. A method including routing optical fibers within the subscriber area, tapping at least one optical fiber with a tap device to interface a downstream optical fiber, and routing at least one optical fiber straight through the tap device.

  • Patent number: 6678442
    Abstract: A fiber optic connector including a body forming a fiber insertion path and an optical lens. The fiber insertion path receives an optical fiber and extends within the body to an internal end. The lens includes a first concave surface formed at the internal end of the fiber channel and a second concave surface formed on an external side of the body. The first and second concave surfaces of the lens are operative to direct light towards each other to enable optical communications between an inserted optical fiber and a connected second connector. Multiple connectors may be incorporated within the same body. A fiber tip cleaner and fiber bonding system may be included within the insertion path. An optical block incorporating the connectors may be configured as a splitter and/or combiner. The connectors and optical blocks may be used to implement a segmented FTTH optical network.

  • Publication number: 20030163831
    Abstract: A hand-held cable communicator unit for technicians that enables voice and data communications across a cable network. The communicator includes a cable connector, a diplex filter, a transceiver circuit, an audio circuit and a control circuit. The transceiver circuit tunes to selected downstream and upstream channels signals. The audio circuit enables bidirectional voice communications using the selected channels signals via the cable network. The control circuit establishes a communication link and initiates and terminates communications. A communication system for field technicians of a cable network includes at least one communicator and a central communicator located at a point of distribution of the cable network. The central communicator includes transceivers, a switch matrix and a controller. Each central transceiver establishes a communication link with any linked communicator. The switch matrix forwards upstream and downstream communications between linked communicators.
