1) When there are multiple new specifications of the same specifications at the same cutting site to penetrate the optical cable, if the ends of each optical cable are not marked with the same color when the cable is put, it is also easy to make mistakes in the same pipe hole.

2) The usual method of treating the old optical cable is usually indicated by the red tape to indicate the retention end, but after dragging the old optical cable out of the human hole, is it the left end of the red tape or the right end of the red tape? In fact, the blue tape should be used to indicate the abandoned end. When cutting, the red end will not make an error when cutting and retaining the red end.

3) In the same section of the old optical cables to be cut, because there are multiple connector boxes, a variety of model optical cables, the joint box is not opened before cutting. Essence

4) In the optical cable cutting of the city line, because the optical cables in different directions take the same pipeline, it is easy to make the direction wrong when cutting.

5) In the on -site cutting safety management, a safety accident will occur if you don't pay attention. If there is no appropriate ventilation, enter the human hole, use bright fire in the human holes, no warning signs around the human holes, no warning signs when pumping water, refuel the oil machine while smoking, and do not use test -electric strokes to work on the pole. , The person in charge of the cutting point began to open the cable without review and consent.

The cutting that can only be done at night is close to the outdoor of 0 degrees. The face, hands, and ears are frozen, but the work in my hand cannot be stopped for a few hours.
