Finally,the paper shows how to confine the cutoff wavelength in an acceptable range or make it more reasonable by changing the drawing tension in actual production.

本文介绍了单模光纤截止波长的理论公式,分析和探讨了拉丝张力这一工艺参数与单模光纤截止波长、模场直径之间的关系,并运用数值分析的方法建立了截止波长和模场直径的关系式,最后指出了在实际生产中,如何通过改变拉丝张力而使得截止波长在合格范围内或更加趋于合理。

The drawing tension is an important parameter in the optical fiber technology.

根据实际情况作适当近似，避开繁琐的流体方程，导出拉丝张力公式。

The dependence of the refractive index of optical fiberes on composition,temperature,warelength, M F D and drawing tension (or drawing temperature) as well as attenuation is described.

叙述光纤折射率与组成、温度、波长、模场直径和拉丝张力 (拉丝温度 )以及衰减等因素的相互依赖关系。
