在向七十年代辞别的时刻,新兴的光纤通信技术的第一阶段可以说已经成熟,这就是,光纤已能正式用来传输市内电话局间线路的PCM数字通信.其光缆、接头、器件、系统,经过工程实验,全都达到技术指标,还证明它蕴藏着巨大潜力.果然,在八十年代起步的第一年,光纤通信技术又以快速的步伐出现,朝向更广阔的范围深入发展,前景是十分令人鼓舞的. 八十年代的头一年,究竟有哪些动向最引人注目呢?我们将在下列三方面谈论这问题.
The first phase of the emerging optical fiber communications technology matured at the time when it farewell to the 1970s was the PCM digital communication that optical fibers were able to formally use to transmit lines between domestic telephone offices. , Systems, through engineering experiments, all reached the technical indicators, but also proved that it contains tremendous potential. Sure enough, in the first year of the eighties, optical fiber communications technology at a rapid pace, toward a broader range of in-depth development, The outlook is very encouraging. What are the most striking trends in the first year of the 1980s? We will talk about the issue in the following three areas.
