1.前言使用发光二极管和激光二极管的光纤通信方式首次将光纤作为传输线代替原来的同轴电缆和双股线等,它较多地应用在电子控制设备方面。光纤通信的引进和实用化,其速度要比当初所预测的快得多,此发展趋势将继续下去。随着光纤技术的发展、光纤以及发光二
1. Preface The optical fiber communication method using light-emitting diodes and laser diodes is the first time that optical fiber is used as a transmission line instead of the original coaxial cable and double-stranded wire. It is widely used in electronic control equipment. The introduction and practicality of optical fiber communication are much faster than originally predicted and this trend of development will continue. With the development of optical fiber technology, optical fiber and light two
