General Technical Requirements For Installation And Placement Of Plastic Optic Distribution Box

General technical requirements for installation and placement of Plastic Optic Distribution Box
I believe we can plastic fiber optic distribution box to install the general technical requirements to give you the correct answer!
1. Plastic fiber distribution box layout should be straight, no twist and cross, should not be squeezed by external forces and operational damage. Power lines, home plastic optical fiber distribution box and other weak buildings within the building cable should be separated from the layout. If it can not be met, the corresponding isolation protection measures must be taken
The Wire reinforced plastic optical fiber distribution box in the transfer box should pay attention to the metal parts to ground.
2. For important users or users with special requirements, should consider providing protection, and according to different circumstances to choose a different protection.
3. Plastic fiber wiring box laying should be fully considered and strictly "fire, anti-rat, anti-extrusion" requirements.
4. Plastic optical fiber distribution box at both ends should have a unified logo, logo should be marked on both ends of the location. Tag writing should be clear, correct and correct. The label should be of a material that should not be damaged.
5. Plastic optical fiber distribution box should be evenly curved, the use of ordinary G.652 fiber radius of curvature should be greater than 30mm, the use of anti-bending G.657 fiber radius of curvature should be greater than (A) 10mm, (B type) 7.5mm, (type C) 5mm.
6. Plastic optical fiber distribution box in the laying of the general use of artificial traction, traction should not exceed the maximum allowable tension of plastic optical fiber junction box 80%. Instantaneous maximum traction force shall not exceed the maximum allowable tension of plastic optical fiber junction box 100N. Main traction should be Added to the plastic optical fiber distribution box reinforcement. Leather line
After the laying of the cable should be released to maintain the natural bending state.
7. The plastic optical fiber distribution box should be used to carry plastic optical fiber distribution box, and in the laying of plastic optical fiber distribution box using the cable tray, the plastic optical fiber distribution box disk can automatically turn to prevent the plastic optical fiber distribution box Being wound.
8. In the plastic optical fiber distribution box laying process, should pay attention to the tensile strength of optical fiber, bending radius, to avoid the fiber was wound, twisted, damaged and stampede.
The minimum bending radius of the plastic optical fiber distribution box should meet the following requirements:
(1) laying process plastic optical fiber distribution box bending radius should not be less than 40mm;
(2) after the fixed plastic optical fiber distribution box bending radius should not be less than 15mm.
9. Building shaft and bridge requirements:
(1) telecommunications shaft should be consistent across the floor, the internal broadband should not be less than 600mm, installed in the cable shaft within the wiring box before the operating distance should not be less than 0.6m.
(2) should be reserved within the telecommunications shaft grounding device.
(3) The installation of the trunking in the shaft should be greater than 50% of the total cable utilization.
(4) vertical part of the vertical shaft of the laying of the cable should be bundled every 1.5 meters to prevent the falling force on the core damage.
10. Horizontal pipe requirements (weak wells to the client):
(1) pipe diameter of the embedded pipe should be used φ20 mm - φ25mm, the length of the buried tube buried pipe length should be controlled within 30 meters, the length of more than 30 meters should be added crossing box. Dark tube must be bent when laying, the routing length should be ≤ 15 meters, and the paragraph may not

There are S bend. Continuous bending more than 2 times, should be installed over the box. All turns are completed with a bend pipe for the standard turning radius. Do not use three links and so on.
(2) the bending radius of the pipe should be greater than 10 times the diameter, when the outer diameter of less than 25 mm, the bending radius should be greater than 6 times the diameter, bending angle of not less than 90 degrees. The radius of the tube shall not be less than 6 to 10 times the outer diameter of the tube.
