摘要
一种新型的相干光纤通信实验系统最近在桂林激光通信研究所完成。该系统用于传输彩色电视信号,其接收灵敏度述-56dBm,比目前的直接探测光纤彩电传输系统的接收灵敏度提高了近14dB。
A new experimental system of coherent optical communication is recently accomplished at the Guilin Institute of Optical Communications in China.The system is used to transmit TV signal. The receiving sensitivity of the system reaches -56 dBm at transmitting TV signal. It is about 12 to 14 dB increased in the receiving sensitivity as comparing with the direct detection of optical fiber transmission system nowadays.
