Optical Cable Impact Test

The role of optical cables is to protect optical fibers from damage in all aspects. In daily use, impact and flattening of optical cables are as common as stretching, so it is of great significance to study the impact and flattening resistance of optical cables. Optical cable impact testing determines the ability of optical cables to withstand impact.
Zhongke Testing Reliability Experiment Center has the mechanical properties of various optical cables and provides professional impact testing services for optical cables.

1. According to different transmission performance, distance and purpose, optical cables can be divided into user optical cables, local optical cables, long-distance optical cables and submarine optical cables.
2. According to the different conditions of transmission conductors and media, optical cables can be divided into metal-free optical cables, ordinary optical cables, and comprehensive optical cables (mainly used for railway dedicated network communication lines).
3. According to different laying methods, optical cables can be divided into pipeline optical cables, direct buried optical cables, aerial optical cables and underwater optical cables.
4. According to different structural methods, optical cables can be divided into flat structure optical cables, layered optical cables, skeleton optical cables, armored optical cables and high-density user optical cables.

1. The mass of the weight or falling weight and the height at which the specimen falls should be adjusted to produce the impact energy value specified in the detailed specification. Unless otherwise specified, the drop height is usually 1.m.
2. Then, impact at the sample position specified in the detailed specification at the rate and number of impacts specified in the detailed specification. During the test, monitoring and inspection will be carried out in accordance with the requirements of the detailed specifications.
