Fault analysis of optical cable lines and emergency repair of obstacles 1.2 Preparation of necessary tools for emergency repair of optical cables

We usually see four laying methods of transmission optical cables, including: overhead, pipeline, direct burial, and waterline. Among them, overhead, direct burial, and pipeline are the most common.

1. Prepare various types of optical cables of more than 200 meters and corresponding connector boxes.

2. Prepare the relevant instruments required, including fusion splicer, optical time domain reflectometer (OTDR), light source, optical power meter, routing detector, megger, and longitudinal stripping knife. And the tool box required for fiber optic cable splicing.

3. In order for emergency repairs to work normally, it is necessary to bring a functioning generator with you when traveling; no matter day or night, at least one battery lamp should be carried per person, in order to facilitate the search for obstacles; in order to prevent emergency repairs Obstacle points are on hillsides or areas that are inconvenient for vehicles to enter, so it is necessary to prepare cables of appropriate length so that external power can be connected in time during emergency repairs.

4. Since the weather is always ever-changing, at least one tent should be prepared at all times to prevent working under rainy or sandy conditions. This is not only good for the staff, but also ensures that the instrument is not damaged.

5. Preparations for emergency vehicle repairs must ensure that the vehicle is fully fueled at all times and operates normally when there is no work. To ensure that there is no delay in emergency repairs and the task is successfully completed. 1.3 Corresponding tools should be prepared for various laying methods of optical cables 1.3.1 Preparation of instrument tools for overhead optical cable line emergency repair 1. Different bamboo ladders need to be prepared according to different situations; to facilitate climbing.

2 , upper pole foot buckles and safety belts;

3. Hooks, splints, nail U-shaped clips and other overhead material accessories. 1.3.2 Preparation of instrument tools for emergency repair of pipeline optical cable lines 1. It is definitely necessary to open the well for emergency repair of pipeline optical cables, so prepare a pair of manhole cover openers when repairing pipeline optical cables. 1.3.3 Preparations for emergency repair of directly buried optical cables and water lines 1 , Prepare related earth-moving tools, shovels, picks, hole shovels, etc.

2. Sometimes it is necessary to go up the pole for inspection. Because many pipes are unearthed, foot buckles and safety belts must be prepared.

2 Obstacle analysis and search Obstacle search is a very important link in emergency repair. It can determine the specific location of emergency repair and the specific cause of the obstacle through relevant instruments. It is a necessary prerequisite for the smooth progress of emergency repair.
