Chanclou, Philippe; Schrenk, Bernhard; Lázaro Villa, José Antonio; Klonidis, Dimitrios; Bonada Bo, Francesc; Saliou, Fabienne; Polo Querol, Víctor; López Pastor, Eduardo Tommy; Le, Q.T.; Brenot, Romain; de Valicourt, Guilhem; Spirou, S.; Soila, Risto; Leino, D.; Tosi Beleffi, Giorgio M.; Tomkos, Ioannis; Chatzi, Sotiria; Teixeira, A.; Costa, L.; Kazmierski, Christophe; Prats, Jordi (2012-04-01)
Article
Accés restringit per política de l'editorialWe propose and experimentally demonstrate a flexible wavelength division multiplexing/time division multiplexing network architecture for converged metro-access environment. Entire passiveness in the fiber plant is ... -
Experimental evaluation and improvement methods for low cost transmitters in long reach PONs
Chatzi, Sotiria; Klonidis, Dimitrios; Tsekrekos, Christos P.; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan; Tomkos, Ioannis (2013-12)
Article
Accés restringit per política de l'editorialIn this paper, we first analyze the degradation stochastic resonance (DSR) effect in the context of adaptive averaging (AD-AVG) architectures. The AD-AVG is the adaptive version of the well-known AVG architecture . It is ... -
L-Band In-Line Remote Amplification for an Extended WDM/PON Ring Architecture
Chatzi, Sotiria; Tomkos, Ioannis; Lázaro Villa, José Antonio; Prat Gomà, Josep Joan (IEEE Press. Institute of Electrical and Electronics Engineers, 2009-06-28)
Text en actes de congrés
Accés obertIn this paper, a study on a fully passive WDM/PON ring architecture which reaches 19 km distance, while serving more than 1000 users with symmetric several hundred Mbit/s per user is presented. The design is based on ... -
Optimization of emerging extended FTTH WDM/TDM PONs and financial overall assessment
Chatzi, Sotiria (Universitat Politècnica de Catalunya, 2013-11-26)
Tesi
Accés obertOptical access technology has experienced a boost in the last years, thanks to the continuously migrating multimedia services that are offered over the internet. Though the technologies used for deploying Fiber-To-The-x ... -
Techno-economics of resilient extended FTTH PONs
Prat Gomà, Josep Joan; Lázaro Villa, José Antonio; Chatzi, Sotiria; Tomkos, Ioannis (IEEE, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialThis work analyses different architectures of protected FTTH passive optical networks in terms of device and infrastructure requirements and costs, considering different home density scenarios and volume projections. The ... -
Wavelength-tuneable remote node for enhanced resilience and optimization of WDM access networks
Lázaro Villa, José Antonio; Bonada Bo, Francesc; Schrenk, Bernhard; Costa, Liliana; Teixeira, Marco Antonio; Chatzi, Sotiria; Klonidis, Dimitrios; Tomkos, Ioannis; Prat Gomà, Josep Joan (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialA remote node design with a wavelength tuneable optical add/drop element is presented and experimentally demonstrated for application in a resilient ring+tree access network architecture. The flexibility of the network ...
