  • CONTROL OF OPTICAL-MODULATION AMPLITUDE FOR BURST-MODE TRANSMISSION
    Publication number: 20230107882
    Abstract: Various embodiments of the disclosed PON system enable approximate leveling of the optical-modulation amplitudes in a sequence of optical bursts received by a system's OLT from a plurality of ONUs. Some embodiments additionally enable approximate leveling of the average optical power, received at the OLT from different ONUs, in such a sequence. Some embodiments may rely on control messaging between the OLT and ONUs to perform one or both types of leveling. The disclosed leveling may advantageously provide an effective tool for optimizing upstream transmission for high-speed TDM-PONs.

  • Systems and methods for avoiding delays for ULL traffic
    Patent number: 11134506
    Abstract: Delays in the transmission of ULL traffic are avoided or substantially reduced by the initiation of opportunistic and probability-based in-band, traffic-free time period windows that do not correspond to time periods of ULL traffic transmissions.
