一、前言光纤是光通信中的核心技术,在低传输损耗、宽频带化等方面得到了飞速发展。光纤不仅用于了通信干线系统,而且在向用户线路、分局网络、电视公用天线等方面扩大其应用范围。此外,有效地利用光纤维的小直径、高绝缘、无感应等特性,作为计测控制系统的信息传输媒介和传感器等的新应用,也在扎实地向实用化发展。
I. Introduction Optical fiber is the core technology in optical communications and has enjoyed rapid development in terms of low transmission loss and wide band. Optical fiber is not only used for the communication trunk system, but also extends the range of applications to subscriber lines, branch networks and television public antennas. In addition, new features such as small diameter, high insulation and non-sensing of optical fiber are effectively used as a new application of information transmission media and sensors for measurement and control systems, and are also being put into practical use.
