92 and 50 Gbps TDM-PON using Neural Network Enabled Receiver Equalization Specialized for PON

Optical Fiber Communications Conference and Exhibition, 2019
Investigation of NN-based equalizers for 50 & 92-Gbps IM/DD NRZ/PAM-4 TDM-PON. NN is universally trained for OLT-receiver for different fiber reaches and ONU wavelength-variations. Care was taken to avoid overestimation of performance due to overfitting.

Comparative Analysis of High Speed 20/20 Gbps OTDM-PON, WDM-PON and TWDM-PON for Long-Reach NG-PON2

Journal of optical communications, 2019
Nowadays, bandwidth demand is enormously increasing, that causes the existing passive optical network (PON) to become the future optical access network.

PON Evolution from TDMA to WDM-PON

OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference, 2008
WDM-PONs are the next step from today's EPONs/GPONs to accommodate further traffic growth and facilitate new applications. WDM-PON variants are analyzed and proposed as solution for a unified optical access and backhauling network.

QAM-PON and Super PON For Access Distribution Networks

Optical Fiber Communication Conference and International Conference on Quantum Information, 2001
We propose a passive optical network (PON) system based on quadrature amplitude modulated (QAM) sub-carrier multiplexing (SCM) of 53 6 MHz 64/256-QAM channels. Sensitivities of -22 dBm and -17.5 dBm are achieved over 51 km of fiber under full duplex and broadcast delivery to 128 nodes for 64 and 256 QAM, respectively.
