非色散位移单模光纤的鉴定与相关检测

The Identification and Testing of Dispersion Unshifted Single-mode Optical Fiber

本文讨论了鉴定未知光纤是否符合非色散位移单模光纤特征的检测过程。光纤种类繁多,在进行鉴定时应结合非色散位移单模光纤的特征进行系统性的检测。检测过程中可首先判断未知光纤是否属于通信用单模光纤,再通过非色散位移单模光纤与其他通信用单模光纤的技术差异进一步鉴定。鉴定过程可能涉及到光纤几何参数、色散系数、宏弯损耗等多项指标的检测,文中给出了推荐的检测方法。

This paper presents the test procedure to identify whether an unknown fiber sample satisfies characteristics of the dispersion unshifted single-mode optical fiber.Since there exists multiple of classifications of fibers,systematically tests are required to accomplish the identification.Firstly it should be determined whether the unknown sample belongs to single-mode optical fiber used in telecommunications,then more tests should be done to distinguish the dispersion unshifted single-mode optical fiber and others.Tests of geometric parameters,dispersion,macrobending loss and many other parameters may be involved during the procedure,appropriate test method is also suggested in the paper.
