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 type of coherent optical fiber communication experiment system was recently completed at Guilin Institute of Laser Communications. The system for the transmission of color television signals, the receiver sensitivity of -56dBm, than the current direct detection of fiber optic TV transmission system sensitivity increased by nearly 14dB.
