光纤通信除了用于数字通信和模拟通信两大类的应用外,还有第三类短距数据通信的应用.所谓短距数据通信,是指光纤在局部或小范围内所用的数据通信网.短距离,是指100米,200米,500米以至2公里.短距数据通信包括点至点(或称定点)的数据线路,和不同型式的数据母线两类.定点数据线路分低
In addition to the application of optical fiber communication in two categories of digital communication and analog communication, there is also the application of the third type of short-range data communication, which refers to the data communication network in which the optical fiber is used locally or in small area. Short distances, 100 meters, 200 meters, 500 meters and even 2 kilometers. Short-range data communications, including point to point (or fixed-point) data lines, and different types of data bus two types.
