1. Cutting preparation

Resource detection: The resource of the resource management system extraction of the resource to be cut into the optical cable is verified on the spot as part of the reporting cutting plan.

Cutting reporting: According to the requirements of cutting on the report, the cutting is reported

Resource review: After the approval is cut, the resource usage of the need to cut the cable segment will be carried out on -site to check and find out on the spot.

Machine preparation: including cutting instruments, vehicles, generators, tents, etc.

Machine connection preparation: machine line contact, determine cutting report, contact and contact telephone number

On -site preparation: Cut the optical cables in advance, human well ventilation, on -site pre -processing, etc.

4. Cutting solution

4.1 inverted fiber solution

The inverted fiber scheme is the first choice plan for the optical cable cutting does not interrupt business. It is suitable for the cutting of optical cable lines with spare optical cables. This solution mainly emphasizes the coordination and cooperation of the machinery and wire affairs departments. The business in the optical cable is all adjusted to the spare optical cable, and the empty cable is cut by the line personnel.

4.2 Circuit scheme

The circuit adjustment method is a way to adjust the circuit that is affected during the optical cable cutting process to the circuit in other optical cables, and it will be cut out after using the optical cable.

At the same time, the circuit adjustment method is also used as an auxiliary method for inverted fiber. Under the circumstances that the spare optical fiber resources are not many, the large capacity and important circuits are inverted, and the circuit is transferred to other circuits.

4.3 Variable Section Scheme

The vertical cutting method is to cut off the circuit without standby optical cable routes. At the same time, it is necessary to use an optical cable to open the skylight to connect the optical cable by or. The vertical dissection method is to block the repair of the core of the optical cable line, which does not affect other optical fibers with good performance.
