光纤通讯具有传输速度快、抗干扰能力强,保密性高、不怕潮湿、耐高温、损耗小等突出优点,目前在国内已成为热门,研制、生产、引进非常活跃,报导文章很多,有人提出:“卫星管天,光纤管地”,想用光纤电缆占领全部通讯阵地,这正和美国1980年前后的情况相似。美国70年代发展起来的光纤,到1979年底其技术发展一般认为已近成熟阶段。当时所罗门兄弟公司(研究市场和新科技发展的顾问公
Optical fiber communication has the advantages of fast transmission speed, strong anti-interference ability, high confidentiality, not afraid of damp, high temperature, low loss and other prominent advantages, at present has become a hot domestic, research and production, the introduction of very active, many articles reported, “Satellite pipe days, fiber optic pipe”, want to use fiber optic cable to occupy all communications positions, which is similar to the situation in the United States around 1980. The optical fibers developed in the 1970s in the United States generally considered the technology development to have reached a mature stage by the end of 1979. At that time, Solomon Brothers (Consultant for Market and New Technology Development
