光纤环绕制过程中的张力分析

结合实际绕制光纤环经验,从绕制方法--四极对称绕法和绕制过程中既是重点又是难点的张力控制角度阐述了对光纤环绕制的几点看法,这些看法是在实际工作经验中总结出来的,希望对提高光纤环绕制的质量有所帮助,并利用一种BOTDR( Brillouin Optical Time Domain Reflectometer )对保偏光纤环的应力分布进行了测试和分析.测试和分析结果表明,BOTDR可用作光纤和光纤环的应力分析和筛选.研究、试验以及实际应用表明,绕环过程中张力控制是绕环质量的关键,精确控制作用于光纤上的外力在适当范围内.

Analysis of stress in winding fiber-optic ring

Some opinions to coiling the optic fiber ring were expatiated from two facets that quadrupole symmetry winding method and stress control which was emphasis and nodus during winding. These views were concluded from the practical winding experiments, and it should be useful to improve the winding quality. The strain distributing in the polarization-maintaining-fiber was measured and analyzed by BOTDR(brillouin optical time domain reflectometer). It shows from the results of the measurement and analysis that BOTDR can be used to filtrate and analyze the optic fiber and optic fiber ring strain. It shows from the research, experiment and application, the stress control during winding a coil is the key fact, it should be remained in a proper range.
