建议ITU-T G.652描述了 一种单模光纤和光缆，其零色散波长约为1310 nm。这个 ITU-T G.652光纤最初被优化用于1310 nm波长区域，但也可以 可用于1550 nm区域。这是最早创建的建议的最新版本 1984年，它进行了一些相对较小的修改。本次修订旨在保持 在不断发展的高性能光纤领域，这种光纤继续取得商业成功 传输系统。

Recommendation ITU-T G.652 describes the geometrical, mechanical and transmission attributes of a single-mode optical fibre and cable which has zero-dispersion wavelength around 1310 nm. The ITU-T G.652 fibre was originally optimized for use in the 1310 nm wavelength region, but can also be used in the 1550 nm region. This is the latest revision of a Recommendation that was first created in 1984 and deals with some relatively minor modifications. This revision is intended to maintain the continuing commercial success of this fibre in the evolving world of high-performance optical transmission systems.
