Abstract: A point-to-multipoint bi-directional wide area telecommunications network employing atmospheric optical communication. The network comprises a primary transceiver unit, a plurality of subscriber transceiver units and an optical router. The primary transceiver unit may send data destined for the subscriber transceiver units through the optical router, and the subscriber transceiver units may send data destined for the primary transceiver unit through the optical router. The primary transceiver unit and optical router communicate by means of light beams which are transmitted through the atmosphere. Similarly, the optical router and the subscriber transceiver units communicate by means of light beams which are transmitted through the atmosphere.

Abstract: A hybrid cable comprising an optical fiber, an intermediate layer surrounding the optical fiber, and an electrically insulating jacket surrounding the intermediate layer. The intermediate layers include a collection of metallic strands. The hybrid cable may be used to establish simultaneous electrical and fiber-optic connection between two communication devices. Thus, the two communication devices may simultaneously transfer optical signals through the optical fiber and perform any of various electrical functions (power transfer, eye safety control) through the metallic strands. For example, an optical transceiver may couple to an optical antenna unit through the hybrid cable. Such an optical transceiver may serve as part of a point-to-point link, a point-to-multipoint link, and/or, a link between a primary transceiver unit and an optical router.

Abstract: A wireless optical transceiver system which includes a passive optical antenna coupled by optical fiber to an active electronics module. The transceiver system receives and transmits light beams from/to the atmosphere,.and thereby communicates optically with a second optical transceiver. Receivers, transmitters, repeaters, switches, routers, etc., may be similarly organized, i.e. by coupling one or more passive optical antennas and an active electronics module with fiber-optic cable. Furthermore, various network toplogies and organizations may be arranged using one or more of the fiber-coupled transceivers, receivers, transmitters, repeaters, switches, routers, etc. Such components are admirably suited for use in various network configurations such as broadcast networks, point-to-multipoint networks, etc due to their low cost, ease of installation and antenna sighting, modularity, and upgradability.
