Patent number: 10523355Abstract: A system and method that enforces one or more policy rules on user-allocated bandwidth portions of the overall system bandwidth, for example in an optical fiber transmission system. The policy rules may limit, for example, the range of optical wavelengths, the acceptable range on the output-power-spectral density and/or the total per-band optical power within the user-allocated bandwidth that a user may provide on the system. The system may include one or more user control units that receives respective user output signals and applies all policy rules. The resulting optical output(s) of the UCU(s) may be provided an optical transmission path for transmission to a receiving terminal. In the receiving terminal, one or more UCU(s) may apply receiver policy rules, for instance by limiting the range of wavelengths transmitted to a receive subsystem.Type: GrantFiled: January 5, 2017Date of Patent: December 31, 2019Assignee: Subcom, LLCInventors: Edwin Muth, Bruce Nyman, Mark Englund, Lara Denise Garrett, Ralph Brian Jander

Patent number: 10110321Abstract: In general, a branching configuration used in a wavelength division multiplexed (WDM) optical communication system, consistent with the present disclosure, includes a power feed branching unit (PFBU) having a multi-port DC/DC converter (DDCM) arrangement capable of a plurality of operating modes to distribute power in a bi-directional manner. The DDCM arrangement may include a plurality of ports for electrically coupling to one or more trunk path cable segments and for electrically coupling to a branch cable segment. A plurality of PFBUs may be disposed along a trunk path, with each PFBU powering an associated branch path, without each branch path necessarily having local power feed equipment (PFE). In instances where a branch path includes a local PFE, an associated PFBU may draw power from the branch path in order to make power available to the trunk path as needed.Type: GrantFiled: March 16, 2017Date of Patent: October 23, 2018Assignee: TYCO ELECTRONICS SUBSEA COMMUNICATIONS LLCInventors: Edwin Muth, Stanley Wisniewski, II, Leonard J. Taylor, Arthur A. Baumgarten

Publication number: 20110206022Abstract: A layer above the MAC and PHY layers of a wireless network employs a forward error correction (FEC) protocol extension with selective acknowledgement to reduce the likelihood of retries to enhance performance in, for example, home entertainment networking applications. In addition, certain system parameters of the wireless network are controlled so as to either i) align required bandwidth with particular sustainable channel parameters of the wireless network, or ii) modify the channel characteristics. One or more of three mitigation techniques might be employed with the FEC protocol extension to enhance maintenance of radio communication in the wireless network: Physical-layer Rate Adaptation, Dynamic Interference Avoidance, and Media-encoding Layer Adaptation.Type: ApplicationFiled: December 28, 2007Publication date: August 25, 2011Applicant: AGERE SYSTEMS INC.Inventors: Anthony J.

Publication number: 20060105702Abstract: A system and method of monitoring Satellite Digital Audio Radio (SDAR) use in which a receiver records and stores radio-use parameters, such as a channel or song being listened to, a time a receiver is active and a signal quality and type in a flash memory. The memory can also be used to store and playback audio files. The user may be incentivised to connect to a central server to download audio material for free or at a discount, so that the stored radio use parameters can be uploaded and analyzed. The user may also be alerted when a preferred or pre-selected song or artist is available on another channel. The network connection may be via wireless access points, or suitable docking units. The receiver may also obtain and record geographical position information from a Global Positioning Satellite (GPS) system, so as monitor reception type and quality by location.Type: ApplicationFiled: November 17, 2004Publication date: May 18, 2006Inventors: Edwin Muth, Jie Song
