摘要

通过控制光纤熔融拉锥参数,实现了光纤熔融拉锥后的抗拉强度增强。利用有限元方法进行模拟与仿真,结果表明光纤熔融拉锥后,光纤内应力的大小与光纤熔融拉锥完成后光纤被加热区域的降温时间有关,降温时间越长,内应力越小,且被加热区域边缘处的内应力值明显高于其他区域的内应力值。根据仿真结果设计实验,实验结果表明,当光纤熔融拉锥完成后光纤被加热区域的降温时间为10、600、1200、1500 s时,光纤熔融抗拉强度将逐渐增强。

Abstract

In this paper, we describe the tensile-strength enhancement of optical fibers obtained by controlling the parameters of the fused biconical tapering process used to produce them. Numerical simulations using the finite-element method show that the internal stress in an optical fiber is related to the cooling time after the tapering process. This stress is reduced by increasing the cooling time, although the internal stress at the edge of the heated area remains significantly higher than that of other areas. Experimental studies based on the simulation results show that the tensile strength of a tapered optical fiber is gradually enhanced as the cooling time is increased from 10 s to 600, 1200, and 1500 s.
