Summary form only given. The massive roll-out of mobile broadband, driven by tablets and smart phones, put tough requirements on the backhaul capacity which quickly become a bottleneck in the mobile networks. Means to increase capacity for different flavours of backhaul (copper, microwave and fiber) are currently being researched; for example ...

PON in adolescence: from TDMA to WDM-PON
IEEE Communications Magazine, 2008Passive optical networks are used for fiber-to-the-home/curb/cabinet/building applications. Today, two PON variants with time-domain multiple access, GPON and EPON, are being used for mass roll-outs. WDM-PONs are the next step up from these PONs to accommodate traffic growth and new applications. This article analyzes WDM-PON variants and proposes they

Performance of OFDM with PCF Configuration in WDM-PON
Optical Transmission Systems, Subsystems, and Technologies, 2011In this paper, we conduct a simulation for WDM-PON with coherent optical OFDM using partial carrier filling (PCF) configuration. The impact of PCF patterns and PCF factor on transmission performance at 40-Gb/s over 100 km are studied and simulated. The influence of power into fiber is examined to obtain the optimal value corresponding to the expected ...

Evolution Scenario Toward WDM-PON [Invited]
Journal of Optical Communications and Networking, 2009In this paper we present and critically discuss different wavelength division multiplexing passive optical network (WDM-PON) architectures compatible with pre-existing gigabit PON (GPON) infrastructures. The concurrent use of the trunk fiber permits a hitless evolution from an existing time division multiplexing optical access network to a point-to ...

Comparison of LED and RSOA performance in WDM-PONs
2014 21st International Conference on Telecommunications (ICT), 2014Currently there is an significant effort by system operators to deploy cost effective Passive Optical Networks (PON). In this way, next generation PON is the subject of studies by researchers and system designers. Among them, Wavelength Division Multiplexing in Passive Optical Networks (WDM-PON) are of particular interest once they can provide larger ...

Reflection tolerance of RSOA-based WDM PON
OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference, 2008We investigate the effects of back-reflection in RSOA-based WDM PON utilizing the remodulation technique. The downstream signal is likely to have severe reflection tolerance (-42 ~ -35 dB), which highly depends on the RSOA gain.

WDM PON Receivers Enhanced by Integrated SOAs
2018 Photonics in Switching and Computing (PSC), 2018The use of multi quantum-well SOAs integrated in a PON receiver including fabrication and loss constraints is modelled, analysed and experimentally validated. Performances were evaluated for a $32 \times25 Gb/{s}$ OOK WDM transmission system in different operating conditions.

Recent Developments in WDM-PON Technology
2006 International Conference on Transparent Optical Networks, 2006Considerable research is being conducted to exploit the potential of novel WDM-PONs exhibiting individual, data and protocol agnostic virtual point-to-point (p2p) links for each ONU. The research focuses on the deployment of uniform building blocks throughout the entire access network and on upgrading the channel data rate efficiently towards 10 Gb/s ...
