Key Exchange with PUF in NG-PON2 Networks

2019 42nd International Conference on Telecommunications and Signal Processing (TSP), 2019
As next generation passive optical networks (XG-PONs) are currently being deployed, the usability and future deployment of next generation PON stage 2 (NG-PON2) are being called into question. This work provides an overview of basic parameters used in generation (stage 2) passive optical networks.

Experimental evaluation of a NG-PON2 network

2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM), 2018
The next generation passive optical network, stage 2 (NG-PON2) constitute milestone in the optical access networks evolution. Currently the requirements of its physical layer, such as a 40 Gb/s of upstream/downstream capacity, using a hybrid WDM-TDM technology with reliability and efficiency in bandwidth and power consumption. The NG’PON2 standard also

Cross-talk in TWDM-PON beyond NG-PON2

Optical Fiber Communication Conference, 2015
We assess the influence of cross-talk on the capability of upgradability of TWDMPON beyond NG-PON2 for a higher number of connected customers and for a higher number of wavelength channels using experiments and simulations.

NG-PON2 Transmission Convergence Layer: A Tutorial

Journal of Lightwave Technology, 2015
The first family of multi-wavelength PON systems, 40-gigabit-capable capable passive optical networks (NG-PON2), has been specified by the Telecommunication Standardization Sector of the International Telecommunications Union (ITU-T). This tutorial, which is based on the author's ECOC'2015 presentation on the topic, offers a comprehensive review of the

Photonic integrated transmitter and receiver for NG-PON2

SPIE Proceedings, 2014
In this paper the authors present a monolithic Photonic Integrated Circuit which includes a transmitter and a receiver for NG-PON2. With this layout it is possible to build an OLT and, by redesigning some filters, also an ONU. This technology allows reducing the losses in the transmitter and in the receiver, increasing power budget, and also reducing ...

25Gbps Quasicoherent Receiver for Beyond NG-PON2 Access Networks

2018 European Conference on Optical Communication (ECOC), 2018
A 25Gbps quasicoherent receiver with simple DSP has been experimentally validated for 25G access networks. It exhibits a sensitivity of -24. 7dBm after 20km SSMF and duobinary decoding and provides a power budget of 25. 7dB.

Lessons Learned from NG-PON2 Systems Developments and Deployment

Optical Fiber Communication Conference (OFC) 2019, 2019
NG-PON2 is a unique departure from the evolution of single channel TDM-PON systems in that rather than increasing service data rates by incrementally increasing symbol rates, NG-PON2 blended TDM-PON with WDM-PON to create a new optical media access technology, TWDM-PON or Time and Wavelength Division Multiplexed PON.
