The outdoor cable is mainly made be stranded loose tube layer

which is used as a twisting unit to fill the gap in the loose cable and its outer diameter should be rounded. At present there isn’t filling rope related standards for optical fiber cable（test methods

projects or acceptance basis）.The purpose of this paper is to explore the oil absorption application performance of filling rope in optical fiber cable and its mechanical properties. Through the analysis of the test results

this paper provides relevant reference suggestions for standards of filling rope in fiber-optic cable industry.
