摘　　要：光纤是由直径为0.1mm的细玻璃丝构成的,又被称为光导纤维。光纤从20世纪80年代开始在通信领域被大规模推广和使用。因为光纤通信具有容量大、传输过程中能量损耗低、抗干扰能力强、不易被侦测、体积小、重量轻、原材料充裕、传输内容多样化和传输线路适应性强等优势,成为现代通讯传输的主体。由于自身限制、制作和操作工艺等原因,光纤在传输过程中的损耗是其架设以及日常维护必须考虑的一个非常重要的问题。Fiber is constituted by the fine fiberglass with the diameter of 0.1 mm, also called optical fiber.Fiber is started to be promoted and used universally in communication fiber from 1980s, and it has been the main body of modern communication transmission because of it＇s advantages of large capacity, low energy during the transimission process, strong anti-interference ability, hard to be detected, small volume, low weight, abundant raw material, diversified transmission content and the strong adaptability of transmission liners. However, due to it＇s own limited conditions ,the technology of manufacture and operation, the loss during the transmission process of fiber is an important question must he consided for it＇s erection and dailv maintenance.
