随着光纤通信的迅猛发展,本所自1977年下半年起开展了光纤光缆的研制工作,经三年多时间的共同努力,已取得了较大的进展。1980年四季度,本所在北京郊区架设了我国第一根架空光缆(六芯),长度为5.5km,经过实际使用,传输彩色电视图象清晰,性能良好。在此基础上,四机部于1980年12月在上海召开了部级鉴定会,GX 60HG 型高稳定低衰减光纤以及 GLG6型光缆通过了鉴定。GX60HG 型高稳定低衰减光纤,采用了环氧——丙烯酸酯涂料增强和有机硅橡胶缓冲层的
With the rapid development of optical fiber communication, the Institute has started the development of optical fiber and cable since the second half of 1977. After more than three years of hard work, great progress has been made. In the fourth quarter of 1980, the first erection of overhead optical fiber cables (six cores) in our country was erected in the suburbs of Beijing with a length of 5.5km. After actual use, the color TV images transmitted by the Company were clear and the performance was good. On this basis, the four-machine department held a ministerial appraisal meeting in December 1980 in Shanghai. The GX 60HG high-stability and low-attenuation optical fiber and the GLG6 optical fiber cable passed the appraisal. GX60HG high stability and low attenuation fiber, using epoxy-acrylate coating and silicone rubber buffer layer
