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

Figure 3(a) presents the gain curve of a commercial InP/InGaAsP multiple quantum well (MQW) layer SOA as a function of input power (P_in) into the SOA for three different bias currents of 125 mA, 175 mA, and 225 mA. Regardless of the bias…
