我所在去年国庆前试制成功低损耗双芯光缆5公里,并与1934所等单位协作架设了我国第一个光缆传输实验系统,成功地进行了1.8Km,8.448Mb/S 数字传输及2.5Km,图象编码传输实验(架空敷设1.1Km及0.6Km2根光缆),码率达10~(-9),图象清晰。在此基础上,为探索光缆传输系统在核试验领域中的应用,今 Last year, before the National Day, I successfully piloted a 5-km low-loss dual-core optical cable and set up China’s first optical cable transmission experiment system in collaboration with 1934 and other units, successfully carrying out 1.8Km and 8.448Mb / S digital transmission and 2.5Km, Image coding transmission experiment (overhead laying 1.1Km and 0.6Km2 optical cable), code rate of 10 ~ (-9), the image is clear. On this basis, in order to explore the application of fiber optic cable transmission systems in the field of nuclear testing, today
