在我国光纤通信因其速度快、传输质量好以及带宽宽等优点恰好适应了各运营商业务量的增长,从而得到了迅猛发展,新技术、新产品、新材料更是层出不穷。目前,在我国各运营商常用的光纤就有G.652光纤和G.655光纤两大类,在同一个网络中或同一个链路中出现不同种类的单模光纤混用的情况已经就不足为奇了。在本文将从连接损耗、色散、折射率分布不同对异型光纤对接的限制、以及非线性效应、异型光纤对接对熔接机的要求、正确采取OTDR测量方法获得真实数据六方面就不同光纤之间相互连接以及不同光纤在同一网络(链路)中的混用进行分析研究,找出异型光纤对接对系统指标产生的影响,本文的结论仅适用于单模光纤之间的对接,文中的异型光纤对接均指单模光纤之间的对接。
In our country, optical fiber communication has been adapted to the growth of business volume due to its advantages such as high speed, good transmission quality and wide bandwidth. As a result, the development of new technology, new products and new materials are endless. At present, there are two kinds of G.652 optical fiber and G.655 optical fiber commonly used in China’s optical fiber carriers. In the same network or in the same link, different types of single-mode optical fibers are mixed to be insufficient Odd In this paper, from the connection loss, dispersion, refractive index distribution of different shaped fiber docking restrictions, as well as non-linear effects, shaped fiber docking requirements of the welding machine, the right to take OTDR measurement method to obtain real data six different optical fiber between each other Connection and different optical fibers in the same network (links) for analysis and research to find out the shape of optical fiber docking on the impact of system indicators, the conclusions of this paper only applies to the single-mode optical fiber docking between the text of the shaped fiber butt Refers to the connection between single-mode optical fiber.
