长途光缆骨干传输网光纤选型建议

目前我国各运营商都在建设自己的光长途骨干传输平台，光纤类型的选择已成为光缆建设的焦点。本文首先介绍了G.652和G.655光纤的特点，对波分复用技术应用于不同光纤的性能进行了比较，介绍了光传输网技术的发展对未来光纤的要求以及新出现的一些光纤，然后提出了在目前情况下长途光缆的光纤选型建议。

Proposal of Optical Fiber Selection in Long-haul Optical Fiber Cable Backbone Transmission Network

At present every operator is building his individual long haul optical fiber cable backbone transmission platform in our country, and the selection of optical fiber has been paid more attention during the construction. This paper introduces the character of G.652 fiber and G.655 fiber at first and makes comparison of the performance of WDM system applied in different fibers. This paper introduces also the requirements to the next generation fiber for the development of optical transmission technology and the newer fiber, and provides the proposal of optical fiber selection in long haul backbone network under current situation finally.
