目前光纤通信受到世界各国的高度重视,正以迅猛的速度发展着,并即将成为现代通信网中的主要传输手段。因此世界上一些工业发达国家对光纤通信这一高技术的标准化工作也十分重视。国际电工委员会(IEC)为促进国际上的统一,在发展光纤通信的同时就不失时机地开展了光纤通信用纤维光学国际标准制订工作。1978年IEC TC46《电线电缆和波导》技术委员会中成立了SC 46E 《纤维光学》分技术委员会制订光纤光缆、光连接器、光分路器等国
At present, optical fiber communications are highly valued by all countries in the world and are developing at a rapid rate, and will soon become the major means of transmission in modern communications networks. Therefore, some industrialized countries in the world also attach great importance to the high-tech standardization work of optical fiber communications. In order to promote international unification, the International Electrotechnical Commission (IEC) has lost no time in the development of fiber optic communications and has worked on the development of fiber optics international standards for fiber optic communications. In 1978, IEC TC46 “Wires, Cables and Waveguides” technical committee established the SC 46E “Fiber Optics” sub-committee to develop fiber optic cables, optical connectors, optical splitters and other countries.
