300-Gbps Discrete Multi-tone Transmission Using Digital-Preprocessed Analog-Multiplexed DAC with Halved Clock Frequency and Suppressed Image

摘要

We demonstrated DMT optical transmission at a net data rate of 250 (gross 300) Gbps with a single EML and a single PD. We used a new DP-AM-DAC, which relaxes the clock frequency requirement and suppresses high-frequency image signal.
