    • 1Gbps full-duplex links for ultra-dense-WDM 6.25GHz frequency slots in optical metro-access networks 

      Altabas, Jose Antonio; Izquierdo, David; Lázaro Villa, José Antonio; Lerin, Adolfo; Sotelo, Félix; Garces, Ignacio (2016-01-11)
      Open Access
      1Gbps full-duplex optical links for 6.25GHz ultra dense WDM frequency slots are demonstrated and optimized for cost-effective metro-access networks. The OLT-ONU downlinks are based on 1Gbps Nyquist-DPSK using MZM and ...
