Share Fiber Optic Splice Closure Of Loss And Construction Solutions

Posted By fiberclosure top     December 26, 2018    


Fiber Optic Splice Closure is found everywhere in the communications industry, but the cable splice closures are not lost during the connection. As for some units in the cable laying, the cable loss caused by the construction is not according to the standard and according to the construction, so that after a few years, the scene of the broken core and the like appears. After the experts began to analyze, it was concluded that the factors of large loss and broken core were mainly because the construction team was not professional, and the quality of the welding personnel was not advanced. So today, we are mainly talking about the reasons and solutions for the loss of overhead construction of optical cables and welding.

I. Construction loss and solution

(1) Reasons for construction loss:

1. In the construction of optical cable, the cable is broken, twisted, twisted and buckled, the vehicle is crushed, the force is uneven, the metal is scratched, the hydrogen loss is formed, and the non-professional construction team and other factors cause the core of the cable to be affected. damage.

2. If the hook direction is not common, the snake bend will be presented. The distance is too small, and the cable is stressed due to excessive sag.

3. The optical cable on the reserved frame is not fixed and strong, and the optical cable is damaged by the impact of external force for a long time.

4. The cable is too tight when laying, and there is no consideration of the natural elastic rate of the cable.

5. During the construction, the optical cable is damaged and enters the water to form hydrogen loss.

6. The cable connector box is not standard, the quality is poor, the device is not standard, and the water is damaged due to damage caused by external effects.

7. When fixing the optical cable, the connector box is pressed too tightly, and the hot sleeve is pressed too tightly and damaged after welding.

8. When the pigtails of the equipment room are bundled with the cable jumpers, the surrounding is not standard, and the appearance of interspersed surrounds is damaged.

(2) Solution

Before the construction, it is necessary to carry out the opening test to see if it matches the manufacturer's test data and conduct scientific and rational distribution.

1. Choosing a high-quality professional construction unit to ensure the quality of construction is crucial. Any negligence in construction may result in cable loss.

2. Actively adopt effective and effective “four harms” of optical cable lines during planning and construction (lightning protection, anti-electricity, anti-corrosion, anti-mechanical damage) and strengthen protection operations.

3. Use the bracket to lift the cable to lay the cable. The cable should be discharged from the top of the cable. Never put the cable into the cable. This will cause the cable to twist. When the cable is deployed, it should be unified and strengthened. To ensure communication dredge, it is necessary to adopt a scientific, reasonable and orderly traction method. The wiring speed should be uniform, about 10m/min, the cable has a tortuous radius of 20D (D is the cable diameter), the speed should not be too fast, and the length of the connection should not be too long. Long, if necessary, you can adopt the method of “8” wording, or you can lay it from the center to the two ends. If there is a corner, you should do a good job of protection.

4. When the optical cable is laid, it must pay attention to the agreed tensile force and the tortuous radius. In the construction of the optical cable, it is necessary to prevent small circles and twists, twists, back buckles and swells. The traction does not exceed the 80% of the promise. The maximum traction does not exceed 100?, the traction should be added to the reinforcement of the cable, especially pay attention not to suddenly yank.

5. When fixing the cable box, do not use too much force. When the cable entering the equipment room is bundled with the fiber jumper, the force should be properly used. It is forbidden to intersperse and tie.

    steel rods etc. Construction is a risky work and serious injury or death of workers or damage to property is a common issue. Roof installation

    With the construction taking place in a factory setting, materials, working conditions, and inventory are more easily regulated.Bathroom remodeler
