WDM-PON Architecture for FTTx Networks
Fiber and Integrated Optics, 2008Abstract 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 ...

We review WDM-PON and its requirements for athermal AWG’s. Athermal AWG’s are commercially available today that can meet the requirements of a variety of WDM-PON designs and provide a cost-efficient and robust critical component.

Self-healing ring-based WDM–PON
Optics Communications, 2010Abstract In this paper, a survivable ring-based wavelength-division-multiplexing (WDM)–passive optical network (PON) for fiber protection is proposed. Protections for feeder fiber and distributed fiber are independent in the scheme. Optical line terminal (OLT) and optical network units (ONUs) can automatically switch to protection link when fiber ...

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 ...

2011 13th International Conference on Transparent Optical Networks, 2011
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 ...
