  • Flexible Rate Passive Optical Network Incorporating Use of Delay Modulation
    Publication number: 20230283377
    Abstract: Apparatus and method are disclosed that utilize a particular delay modulation technique (i.e., Miller coding) to encode 25 Gb/s data for inclusion with the 50 Gb/s NRZ data in a downstream broadcast transmission from an optical line terminal (OLT) to a plurality of optical network units (ONUs) through an optical distribution network (ODN). The specific Miller coding technique allows for a secondary data stream, operating at half the rate of the NRZ data) to supplement the primary 50 Gb/s NRZ transmission, since both signals are recovered using the same clocking circuitry at the ONU.

  • Method And Apparatus For Downstream Timeslot Scheduling In Multi-Rate Passive Optical Networks
    Publication number: 20230283933
    Abstract: An optical line terminal (OLT) operating within a multi-rate PON is configured to perform downstream timeslot scheduling among an associated number of ONUs so as to minimize the change in information rate from one scheduled ONU timeslot to the next. In this manner, the clock recovery component at each ONU is best able to follow the change in information rates, remaining locked on the system clock regardless of the specific implementation of the clock and data recovery (CDR) functionality at a given ONU. The OLT may schedule timeslot assignments that span a pair of adjacent parts (referred to as a two-part cycle), with the first part having timeslots assigned from the lowest information rate (e.g., NRZ) to the highest (e.g., PAM4) and the second part's timeslots assigned in the reverse order; that is, from the highest to the lowest information rate.

  • Managing access to a shared spectrum using a domain proxy
    Patent number: 11751066
    Abstract: A domain proxy receives a request from a base station for allocation of a first portion of a frequency band to support cellular communication in a geographic area that is indicated in the request. The frequency band is available for exclusive allocation to an incumbent device. The base station is required to vacate the first portion of the frequency band in response to the incumbent device arriving in the geographic area and being allocated a second portion of the frequency band that overlaps with the first portion. The domain proxy accesses a policy for the base station from a database and, based on the policy, selectively provides the request to a spectrum access server (SAS) that is responsible for allocating portions of the frequency band.
