N:1 fast protection in NG-PON2
2015 Opto-Electronics and Communications Conference (OECC), 2015This paper proposes a fast N:1 protection mechanism for NG-PON2 network. When failures occur the affected ONUs conduct wavelength tuning to realize fast service recovery. We analyzed data loss from protection using a Markov chain model. The numerical results show the fast protection scheme reduces the disconnection time, and ONU configurations of logic

A New All-Optical OFDM Architecture for NG-PON2
Latin America Optics and Photonics Conference, 2018A new all optical orthogonal frequency division multiplexing architecture based on a Mach-Zehnder interferometer is proposed. Our results shows a throughput of 1.28 Tbps over 100 km of single mode fiber witch is suitable for long reach NG-PON2 applications.

Enabling technologies and signal processing for NG-PON2 and future WDM-PON
2013 9th International Conference on Information, Communications & Signal Processing, 2013Silicon-based optical components are now mature technologies; and they can be used in the time-and-wavelength-division-multiplexed passive-optical-network (TWDM-PON) optical networking unit (ONU) to increase the level of integration for cost reduction. We will also discuss the further migration form the NG-PON2 to the future pure WDM-PON.

Extending capacity in access beyond NG-PON2: WDM vs. TDM
2015 European Conference on Optical Communication (ECOC), 2015Despite the recent standardization of TWDM PON by ITU-T, continued progress in increasing TDM PON capacity is essential in providing per-wavelength capacity upgrades to TWDM PONs or as an alternative TDM-only solution. We discuss candidate technologies for high-rate single-wavelength PONs.

Increasing TDM Rates for Access Systems Beyond NG-PON2
Journal of Lightwave Technology, 2016Despite the first ever standardization of a passive optical network (PON) that exclusively uses an expansion in the wavelength domain rather than the time domain to enhance network throughput, continued progress in increasing time-division multiplexed (TDM) PON capacity is essential in providing per-wavelength capacity upgrades to time- and wavelength ...
