Real -Time 400 Gbit/s PAM-4 Optical Link over 30 km for Future Access Network
Résumé
We experimentally demonstrate a 4i, WDM real-time 100 Gbit/s/i, PAM-4 fiber link supporting 30 km of fiber propagation and 23.5 dB supported channel insertion losses using analog pre -equalization and common semiconductor based optical pre -amplification.
