  • Patent number: 12095556
    Abstract: Systems and techniques for forward error correction decode processing power reduction are described herein. A first codeword is identified in a network transmission. A conditional decoding window is generated that begins with the first codeword. The conditional decoding window is aligned with a frame of the network transmission. A report is generated that includes an indication of relevance of the conditional decoding window to a network device. The conditional decoding window and the report are transmitted to the network device. A conditional decoding window is received that includes a first codeword. The first codeword is decoded to determine a second codeword. A report is obtained that includes a codeword relevance bit for the second codeword. Upon a determination that the codeword relevance bit indicates that the second codeword is irrelevant, the second codeword is discarded without decoding the second codeword.

  • Patent number: 9806845
    Abstract: Systems and techniques for mitigating spectral excursions in a passive optical network (PON) are described herein. A spectral excursion may be determined in the PON. The spectral excursion may indicate a laser transmission output on the PON at a wavelength that is outside a designated wavelength range. A duration may be identified for the spectral excursion. A first preamble offset may be generated using the duration of the spectral excursion. A round trip delay for the PON and a local time of day may be determined. The first preamble offset, the round trip delay, and the local time of day may be transmitted to an optical line terminal (OLT).

  • Patent number: 9048946
    Abstract: A method of ranging comprises broadcasting a discovery request to a plurality of optical network units and receiving a respective discovery response from one or more of the plurality of optical network units. Each respective discovery response is transmitted as an out-of-band signal. The method also comprises approximating a respective out-of-band round trip delay to each corresponding optical network unit based on the respective discovery response; dynamically adjusting a size of a respective quiet window for each optical network unit based on the approximated out-of-band round trip delay; determining when to start the quiet window for each corresponding optical network unit based on the respective approximated out-of-band round trip delay; receiving an in-band ranging signal from the corresponding optical network unit during the respective quiet window; and determining an in-band round trip delay estimate based on the in-band ranging signal received during the respective quiet window.
