摘要：

The authors have achieved -30.8 dBm (630 photon/bit) receiver sensitivity at 10 Gb/s, with an Er3+-doped optical fiber preamplifier. This is an 8.3 dB sensitivity improvement, compared to the APD/FET receiver. Furthermore, power penalties caused by a noise increase owing to the Rayleigh backscattering of a transmission optical fiber have been evaluated. About - 30 dB Rayleigh scattering from a 20 km optical fiber brought 3.5 dB power penalty for a 25 dB gain optical amplifier. © 1990 IEEE
