近几年来,光纤在局部地区网(Local Area Network,简写LAN)的应用引起广泛兴趣,有可能越来越快地得到发展.尤其为了推行工厂、企业和办公室自动化,迫切需要局部地区网,以传输工厂企业或办公室本身各单位间的来往数据通信;而光纤、光缆、光器件、光端机组成的光纤通信系统,已经研制和发展得相当成熟,用于局部地区网极为合适,可形成局部地区光纤数据网.
In recent years there has been widespread interest in the use of optical fibers in Local Area Networks (LANs), and it is likely to grow faster and faster, especially in the area of factory, business and office automation. Transmission factory business or office itself between the various units of data communication; and optical fiber, optical cable, optical devices, optical fiber optic communications system composed of components, has developed and developed quite mature for local area network is very suitable for the formation of local optical fiber Data Network.
