The maintenance cycle of outdoor fiber optic cables needs to be formulated in layers according to the environment and usage.
Outdoor fiber optic cables should be inspected at least once a week, with a focus on checking for external damage, external force hazards and path abnormalities.
Outdoor fiber optic cables should be fully inspected once a year to test the fiber attenuation performance, clean the surrounding environment and repair wear points;
Outdoor fiber optic cables should be inspected for sealing of joint boxes, stability of fixtures and effectiveness of grounding protection every quarter.
Outdoor fiber optic cables should be inspected immediately after extreme weather such as heavy rain and typhoons, and faults should be immediately checked when signal attenuation or abnormal bit error rate is found.
Use OTDR and other equipment to continuously monitor transmission quality, and shorten the maintenance cycle to once a month for high-load or vulnerable sections.
