  • Patent number: 11736840
    Abstract: A method may include transmitting an open contention-based grant to optical network units (ONUs) and receiving, from at least one of the ONUs, a response to the open contention-based grant. The method may also include determining whether a collision has occurred in response to the open contention-based grant. The method may further include provisioning grants to ONUs in response to determine that a collision has occurred.
    Type: Grant
    Filed: April 5, 2021
    Date of Patent: August 22, 2023
    Assignee: Verizon Patent and Licensing Inc.

  • Patent number: 11706547
    Abstract: An optical device may include a communication interface and processing logic configured to receive a broadcast contention-based allocation from an optical line terminal (OLT), wherein the contention-based allocation is associated with activation of the optical device in an optical network. The processing logic may also be configured to transmit a message in response to the contention-based allocation, wherein the message includes information identifying the optical device and receive, from the OLT, an assignment message or a feedback message in response to the transmitted message. The processing logic may be further configured to execute a retransmission procedure based on the assignment or feedback message indicating that a collision occurred.

  • Patent number: 11616592
    Abstract: A method may include determining a number of categories associated with optical network units (ONUs) in a system and assigning an allocation identifier to each of the respective categories. The method may also include transmitting the assigned allocation identifiers to the ONUs and transmitting a contention-based allocation to the ONUs, wherein the contention-based allocation includes a first one of the allocation identifiers.
