Patent number: 11695593Abstract: Embodiments include a power distribution access network comprising power sourcing equipment (PSE) having a hybrid power-data port and at least one remote distribution node coupled to the PSE. The PSE delivers power at a first voltage to the distribution node and the distribution node delivers power at a second voltage to a remote device. Delivery of power to the distribution nodes may be based on information from the distribution node. Other embodiments include a power distribution access network with remote distribution nodes daisy-chained together by hybrid power-data cables so that a power line and a plurality of optical lines pass along the distribution nodes. The optical lines sequentially drop off along the chain and a remainder of the optical lines is indexed at each distribution node. Remote powered devices are coupled to the distribution nodes. Each remote powered device receives power and optical signals from the respective remote distribution node.Type: GrantFiled: November 24, 2020Date of Patent: July 4, 2023Assignee: CommScope Technologies LLCInventors: David James Mather, Ian Miles Standish, Jan Jozef Julia Maria Erreygers

Patent number: 11588571Abstract: Signal distribution arrangements are assembled by selecting a terminal body and a tap module combination that provides the desired signal strength at the intended position in an optical network. Each terminal body includes an input connection interface, a pass-through connection interface, a module connection interface, and multiple drop connection interfaces. Each tap module houses an optical tap having an asymmetric split ratio. Most of the optical signal power received at the signal distribution arrangement passes to the pass-through connection interface. A portion of the optical signal power is routed to the drop connection interfaces (e.g., via a symmetrical optical power splitter). The tap module and terminal body combination are selected based on the desired number of drop connection interfaces and to balance the asymmetric split ratio with the symmetric split ratio.Type: GrantFiled: January 7, 2022Date of Patent: February 21, 2023Assignee: COMMSCOPE TECHNOLOGIES LLCInventors: David James Mather, Jan Jozef Julia Maria Erreygers, Salvatore Tuccio

Publication number: 20220390676Abstract: Optical wavelength division multiplexing (WDM) devices include an optical chip having a number of waveguides therein, with a common optical fiber and single wavelength channel optical fibers optically coupled to the waveguides. Wavelength sensitive filters are disposed between the chip and the fibers, or across waveguides within the chip to reflect light at certain wavelengths and to transmit light at other wavelengths. In sonic embodiments, all of the fibers are located at the same end of the chip, in others the common fiber is located at one side of the chip and the single channel fibers located at another side, while in others the common fiber is located at a first side of the chip and the single channel fibers are located either at the first side of the chip or at a second side of the chip.Type: ApplicationFiled: October 23, 2020Publication date: December 8, 2022Applicant: COMMSCOPE TECHNOLOGIES LLCInventors: Jan WATTÉ, David James MATHER, Jan Jozef Julia Maria ERREYGERS, Saurav KUMAR, Vivek PANAPAKKAM VENKATESAN

Publication number: 20220086540Abstract: Switching technology may be incorporated into various systems, components, and/or architectures in a fiber optic network to promote network reconfigurability and design flexibility. A signal access unit comprises an input, an output, an access port, a switch arrangement including a switch, and a controller. The switch optically couples the input to the output and not to the access port when in a first configuration, and optically couples the access port to at least one of the input and the output without optically coupling the input and the output together when in a second configuration. The controller is configured to receive an indication of a selected wavelength and to operate the switch arrangement to change the switch between the first and second configurations based on the indication of the selected wavelength.Type: ApplicationFiled: September 3, 2021Publication date: March 17, 2022Applicant: COMMSCOPE TECHNOLOGIES LLCInventors: Olivier Hubert Daniel Yves ROUSSEAUX, Joseph Christopher COFFEY, David James MATHER, John Charles CHAMBERLAIN, Erik J.

Patent number: 10877159Abstract: A method of tracking a plurality of signals from a single satellite comprises receiving a first signal transmitted by a satellite; receiving at least a second signal transmitted by the same satellite; applying a pre-filtering process to determine the cumulative in-phase and quadrature components of the first, second signals, and optionally any further signals; and applying a filtering process to the cumulated in-phase and quadrature components of the first and at least second signals to determine a range and range rate of the satellite; wherein the filtering process comprises applying a Kalman filter. The method results in a determination of the range and range rate from a single satellite with improved signal to noise ratio. The range and range rate so determined may be used, with data from other satellites, to produce a navigational position. The method may be used with each such satellite used in producing the navigational position.Type: GrantFiled: May 18, 2017Date of Patent: December 29, 2020Assignee: QINETIQ LIMITEDInventors: Anthony Pratt, Christopher James Mather
