Test Background
Since communication optical cables are laid on actual lines, they will encounter various unfavorable natural environmental conditions or the influence of human factors. Therefore, people should design and manufacture optical cables that can withstand any environmental conditions they may face based on in-depth research on the temperature attenuation, water seepage, grease dripping and evaporation, wind accumulation vibration, pulleys, dancing, resistance to electrical tracking, and flame retardant properties of optical cables.
Optical cables should have good temperature attenuation performance, sufficient mechanical strength, prevention of water penetration, resistance to electrical tracking, flame retardancy and other properties according to the environmental requirements of their use. Optical cable environmental performance testing can determine its environmental adaptability.
Zhongke Testing Reliability Experiment Center has the environmental performance of various optical cables, and provides professional environmental performance testing services such as temperature cycle testing, water penetration testing, aging testing, and hydrostatic pressure resistance testing 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.
