现代科学技术飞速发展使光通信进入了一个新的时代,与其他通信手段相比,光通信以其传输容量大、传输质量高、单位话路千米造价低等特点显示出极大的优越性,并在通信领域中占据越来越重要的地位。 人类为了传递信息,最早使用的就是光通信。据《资治通鉴》记载,早在公元前773年我国就有幽王烽火戏诸侯的故事,可知在周朝时期就已经用烽火来传递信息,这种原始的光通信就是现代光纤通信的前身。 With the rapid development of modern science and technology, optical communication has entered a new era. Compared with other means of communication, optical communication shows great superiority due to its large transmission capacity, high transmission quality and low cost per kilometer , And occupy more and more important position in the field of communication. In order to transmit information, humans first used optical communications. According to “Zi Zhi Tong Jian” records, as early as 773 BC, there is the story of our warlord Youxu opera, we can see that during the Zhou Dynasty had been used to spread the message of war, the original optical communications is the predecessor of modern optical fiber communications .
