Experimental setup of the short range (SR) scenario employs digital-to-analog converter (DAC), attenuator (Att), vertical cavity surface-emitting laser (VCSEL), multimode fiber (MMF), photodiode (PD), and analog-to-digital converter (ADC); setups for long range (LR) and extended range (ER) additionally employ externally modulated laser (EML), multiplexer (MUX), standard single mode fiber (SSMF), semiconductor optical amplifier (SOA), and demultiplexer (DEMUX).
