How Is the Fiber Optic Splice Box Grounded?

Fiber access terminal box series products are auxiliary equipment for terminal wiring in optical fiber transmission communication network. Features of optical cable terminal box Beautiful appearance, convenient construction, small additional loss, reasonable structure, reasonable structure, main technical indicators, mechanical properties:
After the following tests, the box body of the fiber termination box and all parts in the box should be unchanged, and the optical fiber inspection should be carried out if necessary.
1. Tensile: The cable terminal box and an optical cable should be able to withstand an axial tensile force of not less than 500N, and the axial tensile force of not less than 5N between any wiring pigtail.
2. Flattening: All sides of the optical cable terminal box box should be able to withstand a vertical static pressure of not less than 200N.
3. Torsion: The optical cable terminal box should be able to withstand the torsion angle of ±90o, a total of three cycles of torsion. Electrical performance:
(1). Insulation resistance: The insulation resistance between the metal components of the optical cable splice box and the metal reinforcing core of the optical cable, between the metal components of the optical cable, and between the metal components of the optical cable and the ground should not be less than 2*104MΩ [the test voltage is 500V (DC)].
(2). Withstand voltage strength: under the action of 15KV DC for 1min between the optical cable terminal box and the metal strength core of the optical cable, between the metal components of the optical cable, and between the metal components of the optical cable and the ground, there will be no breakdown and no arcing phenomenon. Optical performance: The remaining optical fibers in the fiber termination box are coiled in the splice tray, and the optical fibers and optical fiber connectors should have no additional attenuation after the installation and operation of the optical cable terminal box.
