What work needs to be done for the optical cable entry box?

a. It must be ensured that the line cable is thoroughly roughened at this part to enhance the adhesion between the non-vulcanized rubber tape and the cable. In the project, the optical cable here is applied with No. 8 sandpaper, and the optical cable is used as the axis to be evenly roughed in a circular shape until the luster of the outer sheath of the optical cable disappears completely, and then the residual sandpaper particles on the outer sheath are removed with cotton yarn. Finally, the non-vulcanized rubber tape is stretched in the horizontal direction and evenly wound on the optical cable. The thickness of the winding should be higher than the extrusion recess between the upper and lower covers of the splice box. After the splice box is closed, the traces of the non-vulcanized rubber tape being pushed out of the box can be clearly seen from the outside of the splice box.

b. The cleanliness of the non-vulcanized rubber belt must be ensured. Due to the limitation of the outdoor geographical environment of some optical cable splicing points and the negligence of the operator, if the non-vulcanized rubber tape is stuck with impurities before use, its viscosity will decrease, resulting in a decrease in the moisture resistance of the splice box after packaging.

c. The unvulcanized rubber belt must be stretched and wound according to the specifications. In order to ensure that the non-vulcanized rubber tape can connect the optical cable splice box and the line optical cable as a whole, and there is no gap between the layers of the non-vulcanized rubber tape, the operator should stretch it evenly when winding. If the tensile force is not enough, it is impossible to make it evenly wound, and there will inevitably be gaps after the joint box is packaged; if the tensile force is too large, it will break.
