One. After the user receives the optical cable, checks the optical cable certificate and the disk light data, checks the optical cable plate number, the type, the core number and the length and so on, and inspects the outer packing to have the broken loss.
Two. When the fiber-optic cable is placed, it should be connected with a traction rope and a cable reinforcing piece, and fixed with the sheath or tape. If the pipeline cable, traction rope and cable reinforcement between the need to add a dedicated rotating traction head, do not allow direct pull cable outer sheath traction.
Third, for 2KM or more of the length of the cable arm, do not allow a one-off from beginning to end, you need to put the optical cable disk in the middle of the lot, inverted 8 to both ends.
Four. When uninstalling an optical cable from a car, it is best to use a forklift or hoist to gently place the cable from the car.
Five. In the field of construction, the unloading of optical cable from the car should be placed in a flat bar between the car platform and the ground, forming a slope of 45 degrees with a rope through the middle hole in the cable, people in the car pull the ends of the rope, is the fiber optic cable down the slope of the board downhill.
Unloading optical cable is when, rigorous stacking, flat, is strictly prohibited directly from the height of the cable from the vertical drop down, placing a strong impact on the cable damage.
Six. When you need to scroll the optical cable, you should scroll in the direction of the rotating arrow indicated by the disk, but not long.
Seven. Before construction, the optical fiber cable should be tested on a single disk, such as the outer sheath quality and attenuation index.
Eight. The maximum pulling force of the pipe or aerial cable is not more than 1500N, and the maximum pulling force is not more than 3000N when laying the direct buried cable.
