Methods and precautions for Dongguan optical cable construction The most important thing for long-distance Dongguan optical cable laying is to choose a suitable path.
Here, the shortest path is not necessarily the best. Pay attention to the land use rights, the possibility of erection or burial, etc.
It is necessary to have complete design and construction drawings to facilitate construction and future inspections.
During construction, always be careful not to subject the Dongguan optical cable to heavy pressure or be punctured by hard objects.
When the optical cable turns, its turning radius must be greater than 20 times the diameter of the optical cable itself.
1. Dongguan optical cable outdoor construction: Generally used for long-distance secondary or Lines below level two are suitable for dedicated network optical cable lines or some local special areas.A. The overhead hanging method is simple and cheap. It is widely used in my country, but it is time-consuming to add hooks and organize.
B. Suspension wire winding overhead method, this method is more stable and requires less maintenance.
But a special wrapping machine is required.
C. The self-supporting overhead method has high requirements on line trunks, difficulty in construction and maintenance, and high cost. It is rarely used in China.
D. When overhead, a guide device must be installed at the trunk where the fiber optic cable is led, and the fiber optic cable must be prevented from dragging the floor.
Be careful to reduce friction when pulling Dongguan optical cable.
A section of optical cable should be left on each trunk for telescopic purposes.
E. Pay attention to the reliable grounding of metal objects in Dongguan optical cables.
Especially in mountainous areas, high-voltage power grid areas and multi-region areas, it is generally necessary to have 3 grounding points per kilometer, or even use non-metallic optical cables.
