“光”意味着什么?光明和光速。众所周知,光是传播最快的介质,其速度惊人,每秒30万公里,这意味着从北京到纽约也就是一眨眼的功夫。光纤作为光的载体,它可以把这种高速传遍全球,由此发展而来的炙手可热的光通信则具有高速率、大容量、高质量的突出优点。由此,有人发出梦想:如果有一天光能像电一样成为我们日常生活中的通信方式,那坐在家里,享受来自世界各地丰富的信息,沟通无止境该有多好。光通信无疑是目前发展最快的领域之一,其性能达到每9个月翻一番,比摩尔定律中芯片每18个月翻一番还快一倍,在
What does “light” mean? Brightness and speed of light. It is a well-known fact that light is the most rapidly spreading medium, at an alarming rate of 300,000 kilometers per second, which means blink of an eye from Beijing to New York City. Optical fiber as a carrier of light, it can spread this high-speed throughout the world, the resulting hot optical communication has the outstanding advantages of high-speed, high-capacity, high-quality. As a result, some people have a dream: If one day light can become the means of communication in our daily life like electricity, then sitting at home and enjoying the rich information from all over the world, how good communication can be. Optical communications is undoubtedly one of the fastest growing areas at present, with its performance doubling every nine months and twice as fast as Moore’s Law doubling its chips every 18 months.
