Roy B. TEBBE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Signal detection for optical communication network
    Patent number: 10348479
    Abstract: In at least some example embodiments an optical line terminal (OLT) may include processing circuitry configured to, convert an optical signal received from an optical network terminal (ONT) to a digital signal; and monitor the digital signal for a convergence event, the digital signal representing an optical signal received from the ONT and the convergence event being an event associated with the ONT.
    Type: Grant
    Filed: May 26, 2017
    Date of Patent: July 9, 2019
    Assignee: NOKIA OF AMERICA CORPORATION
    Inventors: Roy B. Tebbe, Kaleb Droskiewicz
  • Method and apparatus for reducing preamble length in passive optical network (PON) systems
    Patent number: 10320514
    Abstract: A method of handling upstream data transmissions in a passive optical network includes determining signal power levels of a plurality of optical network units (ONUs); and scheduling transmissions of upstream data bursts of the plurality of ONUs by, assigning each of the upstream data bursts to one of two or more data burst groups based on the determined signal power levels, and selecting time intervals during which the upstream data bursts are transmitted in accordance with the two or more data burst groups such that the two or more data burst groups are scheduled to be transmitted sequentially.

  • Devices and methods for estimating received signal strengths in passive optical networks on a burst-by-burst basis
    Patent number: 10277314
    Abstract: The received signal strength of individual optical data bursts may be estimated based on the detection of bit patterns within each data burst associated with an amplifier recovery time period. The burst-by-burst estimates can be made faster than existing techniques.
