Test Background
The optical cable UV resistance test can determine the ability of the optical cable sheath to maintain its performance integrity when exposed to sunlight or fluorescent lights and ultraviolet (UV) radiation (when applicable). The maintenance of performance integrity is evaluated by measuring the tensile strength and elongation at break of the optical cable sheath sample.
Zhongke Testing Reliability Experiment Center has the ability to test the environmental performance of various optical cables and provides professional ultraviolet resistance testing services for optical cables.
Scope of tests
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.
Test method
1. Before irradiation, measure the tensile breaking strength and breaking elongation of the comparison sample in a tensile testing machine.
2. When applicable, irradiate the sample. After irradiation, test the tensile strength and elongation at break of the sample in the same way as the comparison sample.
