At this stage

it is a period of rapid development of the Bow-type optical fiber cable.However

many problems have arisen during its development.The fiber breakage problems are in particular in the production process.This not only affects the improvement of the manufacturer’s production capacity

but also makes the section length cannot meet the customer’s requirements

which brings the problems such as goods overstocking and cannot be used for other issues.What is the root reason for the breakage of the bow-type optical fiber cable? How to solve or improve the problem? In this paper

the reasons for the breakage of the bow-type optical fiber cable are analyzed and the corresponding improvement schemes are put forward accordingly.
