Planning and designing FTTH networks: elements, tools and practical issues
Segarra Mullerat, Josep; Sales Zaragozá, Vicente; Prat Gomà, Josep Joan (IEEE, 2012)
Text en actes de congrés
Accés restringit per política de l'editorialFiber-To-The Home (FTTH) provides the offered and new broadband services. Now it is deployed massively worldwide with Passive Optical Networks (PONs), being the EPON and GPON standards the most used. In this paper we ... -
Practical design of a coherent ultra-dense WDM-PON with paired DFB lasers
Segarra Mullerat, Josep; Sales Zaragozá, Vicente; Polo Querol, Víctor; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2020)
Text en actes de congrés
Accés restringit per política de l'editorialA coherent WDM-PON achieving ultra-dense spectral allocation is reported. The ONU at user premises is built of coherent transceivers with two paired low-cost DFB lasers, one as local oscillator and the other as transmitter, ... -
Practical fast and non-intrusive ONU activation procedure in coherent udWDM-PON
Polo Querol, Víctor; Tabares Giraldo, Santiago; Canals, X; Segarra Mullerat, Josep; Prat Gomà, Josep Joan (2023-04-15)
Article
Accés restringit per política de l'editorialThe development of coherent high density WDM PONs, forecasted as one of the promising technologies to increase the spectral efficiency and reduce the energy consumption, can be obstructedbythe limited tunability, high ... -
SARDANA: an all-optical access-metro WDM/TDM-PON
Spirou, S.; Tomkos, Ioannis; Prat Gomà, Josep Joan; Segarra Mullerat, Josep; Sales Zaragozá, Vicente; Lázaro Villa, José Antonio; Chanclou, Philippe; Soila, Risto; Teixeira, A.; Tosi Beleffi, Giorgio M. (2011)
Text en actes de congrés
Accés obertA new optical access network, named “Scalable Advanced Ring-based passive Dense Access Network Architecture” (SARDANA), is presented. It transparently integrates WDM metro and TDM PON access technologies, implementing ... -
Statistical UDWDM-PONs operating with ONU lasers under limited tunability
Sales Zaragozá, Vicente; Segarra Mullerat, Josep; Polo Querol, Víctor; Prat Gomà, Josep Joan (2015-02-01)
Article
Accés obertWe explore a new wavelength management for ultradense wavelength division multiplexing- passive optical network with randomly distributed optical network unit (ONU) wavelengths, controlled with limited thermal tunability. ... -
UDWDM-PON using low-cost coherent transceivers with limited tunability and heuristic DWA
Sales Zaragozá, Vicente; Segarra Mullerat, Josep; Polo Querol, Víctor; Velásquez Micolta, Juan Camilo; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2016-08-01)
Article
Accés obertA new Passive Optical Network (PON) for access, making use of Ultra Dense Wavelength Division Multiplexing (UDWDM) by densely spacing channels at few GHz, and introducing the “wavelength-to-the-user” concept, is proposed. ... -
