112.5 Gbit/s long reach passive optical network with over 31 dB power budget enabled by semiconductor optical amplifiers

Abstract We experimentally demonstrate the downstream transmission of 112.5 Gbit/s pulse amplitude modulated (PAM) signals in the O-band for future time-division multiplexed long-reach passive optical networks (LR-PONs). For the first time, this work demonstrates the use of a commercial quantum-well...
