Experimental Evaluation of PAM and Polybinary Modulation for Intra-DCI Optical Lanes with up to 300 Gbit/s Net Bitrates
06 March 2022
We experimentally test PAM and polybinary modulation in a wide range of symbol rates, as potential candidates to realize next-generation optical lanes. 306-Gbit/s bitrate is demonstrated with 140-GBd PAM-6 signal at sensitivity ?17.9-dBm with EDFA-preamplifier. © 2022 The Author(s)
