As the core carrier of modern communication, optical fiber communication cables are widely used in metropolitan area networks, data centers, home broadband and other scenarios. However, their fragile materials and special maintenance make them prone to faults affected by various factors. From years of industry experience, six major problems such as termination faults, bending loss, and environmental impact are the most common. Mastering the corresponding maintenance skills can greatly improve network stability.
Termination and connection faults are frequent problems. End-face contamination, wear or loose connectors will all lead to signal loss. It is recommended to clean the end-face with professional tools before each insertion and extraction, and regularly detect the loss with an optical power meter. Exceeding the minimum bending radius of the optical fiber will cause signal leakage. During wiring, the bending radius must be strictly controlled, and protectors should be installed in areas prone to bending. Environmental factors cannot be ignored. Moisture and extreme temperatures will accelerate the aging of the sheath. Outdoor optical cables should use suitable models and strengthen mechanical protection. In addition, mechanical damage, interface compatibility issues, and signal attenuation also need to be addressed targeted. Prevent faults through standardized identification, electrostatic protection, regular testing and other measures.
The core of optical fiber maintenance is “prevention first”. Only by combining intelligent monitoring equipment with regular inspection plans can the fault rate be minimized and the service life of optical cables be extended.
