  • Field-Trial of a high-budget, filterless, lambda-to-the-user, UDWDM-PON enabled by an innovative class of low-cost coherent transceivers 

    Presi, Marco; Artiglia, Massimo; Bottoni, Fabio; Cano Valadez, Iván Nicolás; Tabares Giraldo, Jeison; Velásquez Micolta, Juan Camilo; Ghasemi, Saeed; Polo Querol, Víctor; Chu Guang, Yong; Prat Gomà, Josep Joan (2017-09-01)
    Article
    Open Access
    We experimentally demonstrate an innovative ultradense wavelength division multiplexing (UDWDM) passive optical networks (PON) that implements the full ¿-to-the-user concept in a filterless distribution network. Key element ...
  • LUT-Free carrier recovery for intradyne optical DPSK receivers in UDWDM-PON 

    Ghasemi, Saeed; Tabares Giraldo, Jeison; Polo Querol, Víctor; Prat Gomà, Josep Joan
    Conference report

    We present an LUT-free feed-forward carrier recovery architecture in intradyne optical DPSK receivers that reduces ~41% DSP hardware resources and 61% required process clocks with 85% less power consumption in real-time ...
  • Optimized differential detection-based optical carrier recovery for intradyne PSK receivers in udWDM-PON 

    Ghasemi, Saeed; Tabares Giraldo, Jeison; Polo Querol, Víctor; Prat Gomà, Josep Joan (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    We present an optical carrier recovery based on differential detection that reduces required DSP hardware resources. Results show -55dBm sensitivity for BER=10-3 and high tolerance against fast LO frequency dithering, with ...
