1. According to the installation position of the machine equipment (optical splitter, ONU), and the specific wiring conditions of the buried pipes and indoor pipes at the entrance, search and clarify the specific address of the entrance pipe.

2. First try to put the leather wire optical cable directly into the buried pipe, if it can be disconnected, the cable threading work is completed.

3. When it is not possible to pass the cable directly, a pipe passer should be used. If the friction resistance of the pipe piercer is relatively large during the threading and releasing process, you can pour a small amount of lubricating fluid into the nozzle or apply lubricating fluid directly on the pipe piercer, and try to thread the pipe piercer into the nozzle again. Can be disconnected.

4. When the pipe threader cannot be disconnected at one end, it can be threaded again from the other end. If it cannot be successful, mark the pipe threader and pull out the traction belt line. , Determine the blocking position, report the situation to the customer, and clarify the cable method again.

5. When the pipe threader is successfully disconnected from the nozzle, connect one end of the threader with the optical fiber cable to make the end of the traction belt of the optical fiber cable that meets the standard (the top of the traction belt line of the pipe threader and the end of the optical fiber cable). The parts are coiled with each other for 20cm and tied with insulating tape, but it does not need to be wrapped too thickly). If there are other cables laid in the same nozzle, lubricating fluid should be applied to avoid damage to other cables.

6. It is very important to cooperate with each other when pulling the leather cable into the tube. It should be done by two people, and they must speak to each other, such as the gradual data signal of the pulling belt, the mutual dynamic password when pulling the belt, The efficiency of the traction belt and the condition of its leather cable, etc. Because the staff at the leash end cannot see the staff at the end of the cable, it is not possible to pull the cable.

7. After pulling the leather cable out of the nozzle, you should use your own hands and eyes to determine whether there are dents or damages on the lead-out section of the leather cable. If there is damage, discard the method of threading the tube.

8. Determine the length of the leather cable, and break the leather cable. Be careful not to cut it too short, and be sure to pre-embed it to make metal mechanical equipment to continuously connect the length of the power plug.
