Optical amplification-free 310/256 Gbaud OOK, 197/145 Gbaud PAM4, and 160/116 Gbaud PAM6 EML/DML-based data center links
Optical Fiber Communication Conference, 2023•opg.optica.org
… For the EML-based transmitter at optical-back-to-back (ob2b) we achieve 256 Gbaud
OOK signal performance below the KR-FEC threshold of 2.1×10-5 and 200 Gbaud PAM4
signal performance below the HD-FEC threshold. This is a significant improvement
compared to [9,10]. … We first show eye diagrams for the EML-based transmitter at ob2b for
256 Gbaud OOK and 200 Gbaud PAM4 signals. Then we show eye diagrams for all
modulation formats and both transmitters after transmission over a different length of SMF …

Abstract
We demonstrate a record 310/256 Gbaud OOK, 197/145 Gbaud PAM4, and 160/116 Gbaud PAM6 EML/DML-based IM/DD links without any optical amplification with performance below the 6.25% overhead HD-FEC threshold after 100-m/6-km SMF, respectively.
