我从1956年到邮电部邮电科学研究院筹备处以来,一直从事通信线路科研工作。先后参加了60路长途高频对称电缆、长途干线中同轴电缆和小同轴电缆的制造和施工技术的研究。在80年代都在全国范围内使用,初步改善了长途通信的落后状态。70年代末,开始全塑市内通信电缆和光缆的研究。经过80年代及以后的发展,国产光缆已经遍布于全国的长途干线网和大部分城市的城域网中,并正在向用户接入
Since 1956, I have been engaged in the research of communication lines since the preparatory office of the Institute of Posts and Telecommunications of the Ministry of Posts and Telecommunications. Has participated in 60 Road, long-distance high-frequency symmetrical cables, long-haul trunk coaxial cable and small coaxial cable manufacturing and construction technology research. It was used nationwide in the 1980s and initially improved the backwardness of long-distance communications. In the late 1970s, the research on telecommunication cables and optical cables in the all plastic city began. After the 1980s and after the development of domestic fiber optic cable has been all over the country’s long-distance trunk network and most cities in the metropolitan area network, and is accessing the user
