全干式光缆拉伸过程中附加衰减的研究

本文对全干式光缆拉伸过程中影响附加衰减的因素进行了探究,对阻水纱与光纤相互扰动模型进行了设想,对阻水纱的材质、模量、热回缩性能进行了测试分析,结合测试结果设计了实验,并论证了改善附加衰减的方法。

In this paper, the factors affecting the additional attenuation in the tensile test of all dry optical cable are explored, the mutual disturbance model between water blocking yarn and optical fiber is envisaged, the material, modulus and thermal retraction performance of water blocking yarn are tested and analyzed, combined with the test results, experiments are designed, and the methods to improve the additional attenuation are discussed.
