Demonstration of SOA-Based IM/DD 1T (280Gbit/s×4) PS-PAM8 Transmission over 40km SSMF at O-Band

We experimentally demonstrate a four-lane O-band IM/DD system. With the aid of semiconductor optical amplifiers and probabilistic shaping, a record bit rate of 1.12Tb/s (280Gbit/s×4) PS-PAM8 signal can be successfully transmitted over 40-km SSMF.
