Recent Developments in WDM-PON Technology

2006 International Conference on Transparent Optical Networks, 2006
Considerable 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 ...

Hitless Dynamic Wavelength Allocation in Coherent WDM-PONs

Optical Fiber Communication Conference, 2016
We introduce a novel algorithm for real-time ONU activation (¿ - assignment) and reconfiguration (¿ - tuning) in WDM coherent PONs. The algorithm prevents service interruption of lighted channels and it is experimentally demonstrated by using real-time fully-analog coherent transceivers.

GPON over WDM-PON

2014
Com o aumento da necessidade de largura de banda nos últimos anos as redes de acesso encontram-se em constante evolução. Sendo que as redes GPON são de momento a principal escolha num âmbito europeu, devido ao aumento de tráfego nos últimos anos, a necessidade de uma nova tecnologia para redes de acesso NGPON2 é um dos principais focos de investigação ...

WDM-PONs Hold Promise for the Long Haul

Computer, 2009
As they face challenging times, networking-service providers are looking to save money by studying the use of relatively new wavelength-division-multiplexing-based passive optical networks to create more efficient systems that increase data rates.

S-band RSOAs for WDM PONs

Optical Fiber Communication Conference and National Fiber Optic Engineers Conference, 2009
We report on a polarisation independent S-band RSOA for WDM-PON applications for the first time. Operation at 1.25Gbit/s over the entire S-band is demonstrated in TO-packaged devices with a path loss capability of ≫25dB.

A Novel Protection Architecture for WDM-PON

COIN-NGNCON 2006 - The Joint International Conference on Optical Internet and Next Generation Network, 2006
We first introduce a novel designing methods to protect WDM-PON. With these designing methods, we propose reliable and cost effective protection architectures. We also study the performance of our proposal in terms of availability and costs.

Overlay of broadcasting signal in a WDM-PON

2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference, 2006
We demonstrate an overlay method for broadcasting signal transmission in a wavelength division multiplexed-passive optical network. We used a low noise broadband light source based on mutually injected Fabry-Perot laser diodes to increase the transmission capacity.

WDM PONs based on colorless technology

Optical Fiber Technology, 2015
Abstract Wavelength Division Multiplexing (WDM) Passive Optical Network (PON) is foreseen to be part of the Next Generation Passive Optical Networks. Business and mobile fronthaul networks already express the need to develop WDM PONs in the access segment.

Dynamic reconfiguration policies for reconfigurable coded-WDM PONs

Photonic Network Communications, 2006
This paper studies the issues arising when reconfiguring coded-WDM networks to provide protection against eavesdropping and it proposes a tradeoffs involved in carrying out this reconfiguration process. It commences by showing that the degree of confidentiality (DOC) and the traffic loss are two important, but conflicting, objectives in the design of ...
