Characterization of a High Capacity Multi-User Optical Access Network Using 1 Gb/s 16 QAM Subcarrier Multiplexing

摘要

Error free operation assuming common FEC techniques is experimentally demonstrated for a multi-user optical access network based on 40 channel DWDM-PON infrastructure and Gigabit Ethernet 16 QAM subcarrier multiplexing transmission. Such a system would support 400 users with symmetrical 1.25 Gb/s connections and media independent final connectivity. To replicate actual working conditions, the experimental setup relied only on commercially available components and was tested with realistic distance reach and high sub-channel load.
