Description
Summary:S.26527-26532 We report experimental validations of an adaptive 2nd order Volterra equalization scheme for cost effective IMDD OFDM systems. This equalization scheme was applied to both uplink and downlink transmission. Downlink settings were optimized for maximum bitrate where we achieved 34Gb/s over 10km of SSMF using an EML with 10GHz bandwidth. For the uplink, maximum reach was optimized achieving 14Gb/s using a low-cost DML with 2.5GHz bandwidth. 21 Nr.22
