Abstract
We report on an electro-absorption modulator (EAM) integrated laser (EML) based real-time 112â¯Gbit/s (2â¯Ãâ¯56.25â¯Gbit/s) 4-level pulse amplitude modulation (PAM-4) signal transmission in the C-band over 80â¯km of standard single-mode fiber (SSMF). Various operating conditions of the EAM were investigated to find the optimum driving conditions for PAM-4 modulation. When the EAM reverse bias was set to the inflection point of the transfer curve, which was â2.35â¯V, we obtained a bit error ratio (BER) of 4â¯Ãâ¯10â8, which is well below the forward error correction (FEC) limit. The results demonstrate the feasibility of using EMLs for implementation in PAM-4 transceivers for inter-datacenter interconnection (inter-DCI) applications.
