加强材料对光缆强度影响的试验研究

为了对比分析PBO纤维和芳纶纤维对耐高低温光缆的强度影响,分别制作了两种加强材料的光缆,实时监测了光缆断裂前拉伸负荷下1550nm波长光透射性能变化。试验结果表明,PBO纤维加强光缆对光纤的保护方面更具有优势,而在抗拉强度工作时,芳纶加强光缆更为合适。

In order to analyze the effects of PBO and aramid fiber on the strength of high and low temperature resistant optical cable,optical cable was fabricated,and optical transmittance of cable under tensile loads were tested.The test results show that PBO fiber has more advantages in the protection of optical fiber,but aramid fiber is more suitable as strength member when low operation tensile load.
