How to solve the problem of fiber breakage and complete signal interruption caused by stretching, excessive bending, or physical impact?
Improvement methods:
1. Emergency repair: Replace the damaged part with a fiber fusion splicer or pre terminated jumper to ensure that the splicing loss is below 0.3dB.
2. Reinforcement measures: Install damping brackets in areas with frequent mechanical vibrations, such as production lines and equipment bases, to secure the fiber optic path and avoid direct contact with metal edges.
Preventive measures:
1. Select high tensile strength optical fibers (such as armored optical fibers, with a tensile strength of ≥ 500N), and reserve redundant length during wiring (recommended to be ≥ 10%).
2. After installation, use OTDR (Optical Time Domain Reflectometer) to test the integrity of the link and ensure no hidden damage.
