Unbundling in WDM-PON Based on All-Optical Switching

2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
A WDM-PON unbundling solution based on WDM/OTDM conversion is presented. It guarantees high bit-rate scalability, easy reconfigurability, modular unbundling, minimum number of fiber links ...

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.

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.

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.

Spectrum-sliced bidirectional WDM PON

Optical Fiber Communication Conference. Technical Digest Postconference Edition. Trends in Optics and Photonics Vol.37 (IEEE Cat. No. 00CH37079), 2002
We demonstrate a bidirectional wavelength-division-multiplexed (WDM) passive optical network (PON) based on spectrum-sliced technique. This network transmits fifteen 500 Mbps downstream and fifteen 155 Mbps upstream channels over single strand of conventional single-mode fiber.

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 ...

Survivable network architectures for WDM PON

OFC/NFOEC Technical Digest. Optical Fiber Communication Conference, 2005., 2005
We propose and demonstrate a simple self-protecting architecture for WDM PON. The protection time was less than 10 ms, and the power penalty caused by the protection process was negligible.

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.

WDM-PON Architecture for FTTx Networks

Fiber and Integrated Optics, 2008
Abstract Broadband services for residential users in European countries have until now largely relied on xDSL technologies, while FTTx technologies have been mainly exploited in Asia and North America. The increasing bandwidth demand and the growing penetration of new services are pushing the deployment of optical access networks, and major European ...
