摘要：
A Reed-Solomon coded optically preamplified pulse-position modulation system is analyzed. Results are presented at a bit rate of 622 Mbit/s and a wavelength of 1.537 mu m, comparing the system with an equivalent on-off nonreturn-to-zero (OOK NRZ) system. The theoretical results demonstrate that the system offers a potential sensitivity of 7 photons/bit, which represents an improvement of 7.5 dB over the equivalent OOK system and is comparable with that of the best coherent systems reported to date.
