摘　　要：介绍了光缆冰冻故障产生的原因,分析了冰冻对光缆性能的影响,提出可以通过在光缆中设置缓冲层来保证内部光单元及传输性能的稳定。文中阐述了影响缓冲层材料选择的主要因素,以及缓冲层厚度设置的理论依据,并设计了一种具有抗冰冻功能的非金属光缆,对该光缆相关防护性能、机械性能进行了验证试验。试验结果表明:在抗冰冻试验中,设置缓冲层的光缆,其光纤最大附加衰减与残余衰减符合工程应用标准,机械性能均满足YD/T 901—2018要求。Causes of optical cable freezing failures and impact of freezing on the performance of optical cables were introduced and analyzed.Setting a buffer layer in optical cables as a measurement was proposed to ensure stability and transmission performance of the internal optical unit in optical cables.Main factors affecting the selection of buffer layer materials and theoretical basis for setting buffer layer thickness were also described.A non-metallic optical cable with antifreeze function was designed.Besides,relevant protective performance and mechanical properties of the cable were verified.Test results showed that the maximum additional attenuation and residual attenuation of the optical fiber with a buffer layer met the application standards during freezing resistance test,and mechanical properties met the requirements of YD/T 901—2018.
