  • Patent number: 8761564
    Abstract: A modular connector assembly is provided that has both an electrical coupling configuration that complies with the RJ-45 wiring standard and an optical coupling configuration that provides the assembly with optical communications capabilities. In addition, the modular connector assembly is configured to have backwards compatibility with existing 8P8C jacks and plugs that implement the RJ-45 wiring standard. Consequently, the modular connector assembly may be used to communicate optical data signals at higher data rates (e.g., 10 Gb/s and higher) or to communicate electrical data signals at lower data rates (e.g., 1 Gb/s).

  • Patent number: 8755750
    Abstract: A signal canceller includes a dual-drive electro-optic modulator having separate first and second electrical inputs. The first electrical input is coupled to a first portion of a first signal and the second electrical input is coupled to a second signal and to a second portion of the first signal. A laser generates an optical beam that propagates from the optical input to an optical output of the electro-optic modulator. The dual-drive electro-optic modulator modulates the optical beam with the first and second portions of the first signal and with the second signal. The modulation cancels at least some the first signal and generates a modulation signal with reduced first signal modulation component.

  • Patent number: 8750709
    Abstract: A waveguide of radio frequency electromagnetic fields is multi-furcated into a plurality of radio frequency waveguide sections, each radio frequency waveguide section having an optoelectronic modulator electrically coupled to it. Each optoelectronic modulator has an optical waveguide disposed therein such that, in use, light traveling in the optical waveguides of the optoelectronic modulators travels in a direction orthogonal with respect to the direction the radio frequency electromagnetic field travels in the radio frequency waveguide sections. The plurality of radio frequency waveguide sections are fed from a common source of said radio frequency energy.

  • Patent number: 8731405
    Abstract: Radio-frequency identification—(RFID)-based systems and methods for collecting telecommunications information is disclosed. The methods include storing transceiver information in a transceiver and connector information in an optical fiber connector, and then operably connecting the connector to the transceiver. The connection results in an electrical connection that allows the transceiver information to be communicated to the connector. The connector has a RFID tag that generates a connector RFID-tag signal that includes the connector information and the transceiver information. When electronics equipment are connected to the transceiver, electronics-equipment information is passed through the transceiver to the connector so that the electronics-equipment information can be included in the connector RFID-tag signal.

  • Publication number: 20140105606
    Abstract: The invention relates to base stations in communication networks. In more particular the invention relates to cellular base stations such as 3G/4G and WLAN base stations. Some or all of the aforementioned advantages of the invention are accrued with a fully photonic base station (200) that powers itself with solar photons, provides radio network access and relays an optical photonic beam (220, 221, 230, 231) through air encoded with the data from radio signals of computer users and mobile phone users to the Internet and the global telecommunication network. A system engineer can build a network with the inventive base stations in a matter of days. He simply walks to the roof of houses and points the optical beams to other base stations in adjacent houses.

  • Patent number: 8682170
    Abstract: Radio frequency transmission systems often suffer from the problem of co-site interference, where the frequency band of a strong radio transmitter overlaps with the frequency band of a co-located and/or remote radio receiver, such that the transmitter interferes with the ability of the receiver to detect a weak signal of interest. There is a need for a device that can process both the transmitted radio signal and the received radio signal to eliminate such interference. Previous attempts to solve this problem have been unable to cancel in-band interference in excess of 20 to 40 dB stronger than the signal of interest over a broad bandwidth, with large dynamic range, and with a high degree of linearity. Disclosed is a robust system and method for cancelling broadband in-band RF interference that operates in a dynamically changing multipath environment.

  • Patent number: 8639121
    Abstract: A switched wireless system is used to increase the range of peer-to-peer communications. The optically-switched fiber optic communication system includes a head-end unit (HEU) having a switch bank. Cables couple the HEU to one or more remote access points in different coverage areas. The switch bank in the HEU provides a link between the remote access points in the different coverage areas such that devices in the different cellular coverage areas communicate with each other. By using the switched communication system, the range and coverage of communication between devices may be extended such that devices in different coverage areas and devices using different communication protocols can communicate.
