  • Performance monitor for all-optical networks based on homodyne spectroscopy 

    Amrani, A.; Junyent Giralt, Gabriel; Prat Gomà, Josep Joan; Comellas Colomé, Jaume; Ramdani, I.; Sales Zaragozá, Vicente; Rafel, A. (2000-11)
    Article
    Open Access
    The ability to transparently detect performance degradations in all-optical networks is highly desirable. We present an optical signal monitor, based on a frequency supervision system, which can participate in some tasks ...
  • Planning and designing FTTH networks: elements, tools and practical issues 

    Segarra Mullerat, Josep; Sales Zaragozá, Vicente; Prat Gomà, Josep Joan (IEEE, 2012)
    Conference report
    Restricted access - publisher's policy
    Fiber-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 ...
  • Redes de acceso UDWDM operadas con láseres aleatorios de sintonía limitada 

    Sales Zaragozá, Vicente (Universitat Politècnica de Catalunya, 2017-10-25)
    Doctoral thesis
    Open Access
    A new passive optical network (PON) for access, making use of ultra-dense wavelength division multiplexing (UDWDM) by densely spacing channels by a few gigahertz and introducing the "wavelength-to-the-user" concept, is ...
  • 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)
    Conference report
    Open Access
    A 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 ...
