摘要

We experimentally demonstrate 100 Gbaud PAM-8 signals intensity modulation and direct detection (IM-DD) transmission over 2 km standard single-mode fiber (SSMF), based on self-developed O-band transmitter optical sub-assembly (TOSA) with a 3dB bandwidth of 60 GHz. Considering the threshold of 20% soft-decision forward error correction (SD-FEC), a photonic data-center interconnection with net bit-rate of 250 Gbit/s is achieved by only feed-forward equalizer (FFE).
