The daily inspection steps of optical fiber cables usually include the following aspects:
Formulate the inspection plan
Based on the layout, importance and historical maintenance records of optical fiber cables, a reasonable inspection plan should be formulated. The plan should clearly define the frequency of inspections (such as weekly, monthly or quarterly), the inspection routes and key areas.
Prepare inspection tools and equipment
Prepare the necessary inspection tools, such as underground pipeline detectors, optical fiber cleaning tools, readers (for reading the information button information in the inspection marker stones), notebooks and pens, etc.
Ensure that the inspection equipment is in good working condition, with sufficient batteries and complete tools.
Foot patrol
Inspection personnel, carrying inspection tools, should walk along the optical fiber line route and must not detour. Hiking patrols can provide a comprehensive and detailed understanding of the changes along the route.
Check the line route
Observe whether there is any obvious subsidence or excavation on the ground above the route, and whether there is any accumulation of debris.
Check whether the routing identifiers are clear and complete, and whether there are any missing, damaged or buried identifiers.
Pay attention to whether there are any construction activities near the optical fiber lines, such as building construction, road excavation, pipeline laying, etc. These activities may cause damage to the optical fiber cables.
Inspect the pole lines and overhead cables
Check whether the electric poles are tilted, cracked, damaged or have any subsidence of the foundation.
Check whether the pull wire on the pole is firm and whether there is any loosening or broken strands.
Check whether the appearance of the optical fiber cable is damaged, aged or deformed, especially whether there are scratches or cracks on the sheath.
Check whether the optical fiber cables are firmly fixed and whether the hooks are complete and in good condition.
Inspect the pipelines and underground cables
Use professional equipment such as underground pipeline detectors to check whether there is any water accumulation or debris blocking the pipeline.
Check whether the position of the underground optical fiber cables is correct, whether the burial depth is sufficient, and whether there is any displacement.
Check whether the protective layer of the cable is intact and regularly spot-test the performance of the protective layer.
Inspect the terminal and joint parts
Check whether the appearance of the optical cable terminal box, optical fiber distribution frame and other equipment is deformed or damaged, and whether the door locks are normal.
Check whether the connection of the optical fibers inside the terminal equipment is firm and whether there is any loosening or oxidation.
Check whether the sealing of the optical cable joint box is good and whether there is any water ingress or moisture.
Check whether the fiber optic length at the joint is appropriate and whether there is any twisting or compression.
Check other accessory equipment
Check whether the auxiliary equipment such as lightning protection, rodent prevention and insect prevention is in good condition and whether their functions are normal.
Record the problem in detail
During the inspection process, any problems and abnormal situations discovered should be recorded in detail, including the location, nature, and scope of influence of the problems.
Records can be made in paper notebooks or through electronic inspection systems.
Report problems in a timely manner
For any serious problems or abnormal situations discovered, the inspection personnel should immediately report to their superiors so that timely measures can be taken to handle them.
The reporting methods can be by phone, text message, email or the reporting function within the inspection system.
Deal with problems
For problems that can be dealt with immediately, inspection personnel should handle them under the premise of ensuring safety, such as clearing debris and tightening optical fiber cables.
For issues that require professional handling, the inspection personnel should make marks and records, and notify the relevant departments or personnel to handle them.
Feedback the processing result
After the processing is completed, the inspection personnel should record the processing results in the inspection record and promptly feed them back to their superiors.
If necessary, photos or videos of the processing procedure and results can also be taken for record.
Summarize the inspection experience
Regularly summarize and analyze the inspection records to identify the problems and deficiencies existing in the inspection process.
Summarize the successful inspection experiences and practices to provide references for future inspection work.
Improve the inspection work
Based on the results of the summary and analysis, the inspection plan, inspection routes, inspection priorities and methods are improved and optimized.
Introduce advanced inspection technologies and equipment to enhance the efficiency and quality of inspections.
Through the implementation of the above steps, it can be ensured that the daily inspection work of optical fiber cables is carried out in an orderly and efficient manner, potential problems and hidden dangers can be discovered and dealt with in a timely manner, and the safe and stable operation of optical fiber cables can be guaranteed.
