75年以来,光通信已进入了实用化实验研究阶段,为早日实现我国光通信的实用化,我所与1934所,1446所等单位协作,在78年国庆前夕架设成功了第—个1.8Km 架空光缆实验系统进行了。1.8km,8.448Mb/S 数字传输及,2.5Km 图象编码传输实验.误码率达10~(-9),图象清晰,架设至今光缆性能良好,系统运行正
Since 75 years ago, optical communication has entered the phase of practical experimental research. In order to realize the practical application of optical communications in our country as early as possible, I collaborate with units such as 1934 and 1446 to establish the first 1.8Km Overhead cable experiment system was carried out. 1.8km, 8.448Mb / S digital transmission and, 2.5Km image coding transmission experiment. Bit error rate of 10 ~ (-9), the image is clear, set up so far cable performance, the system is running
