一、概述自1970年美国康宁公司首次拉制成功低损耗导光玻璃纤维以来,光纤通信获得了迅猛的发展,世界各主要工业国都迅速地开展了这方面的研究。由于光纤通信具有重量轻、体积小,通信容量大、损耗低、防窃听等优点,在短短十年间,各种光纤通信的实验系统已遍及世界各地,并已由实验研究阶段走向商业化实用阶段。有关专家纷纷预言,在八十年代,光
First, an overview Since 1970, the United States Corning successfully drawing low-loss light-guide glass fiber for the first time since the optical fiber communication has achieved rapid development, the world’s major industrial countries have carried out rapid research in this area. Due to its advantages of light weight, small volume, large communication capacity, low loss and anti-eavesdropping, optical fiber communication systems have spread all over the world in a short period of ten years and have gone from experimental research to commercialization and practicality stage. Experts have predicted that in the eighties, light
