Abstract

This paper mainly studied the tensile strength of the splicing point of optical fibers. We analyzed the main factors that influence the tensile strength of the splicing point during the process of fiber splicing and post processing. The results demonstrate that it is the expansion of little cracks produced during fusion process that decreases the tensile strength of splicing point. We eliminated the cracks on the splicing point by using CO₂ laser based on the principle of crack production and elimination. The experimental result shows that after eliminating the cracks the tensile strength of the splicing point is observably improved and it reaches more than 160kpsi.
