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.

Abstract: Systems and techniques for concurrent optical network terminal simulation are described herein. A data packet may be received by an optical lint terminal. It may be determined that the data packet is associated with an optical network terminal simulation host. The data packet may be modified based on the determination. The modified data packet may be transmitted to a device.

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).

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.
