1Gbps full-duplex links for ultra-dense-WDM 625GHz frequency slots in optical metro-access networks

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 single-detector heterodyne reception obtaining a sensitivity of -52dBm. The ONU-OLT...

Summary: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 single-detector heterodyne reception obtaining a sensitivity of -52dBm. The ONU-OLT uplinks are based on 1Gbps NRZ-DPSK by directly phase modulated DFB and also single-detector heterodyne reception obtaining same sensitivity of -52dBm. The power budget of full-duplex link is 43dB. These proposed links can provide service to 16 (32) users at each 100 (200) GHz WDM channel. (C) 2016 Optical Society of America Peer Reviewed
