Mechanical Performance Of Terminal Box

After the following tests, the stress of the terminal box body and various parts inside the box changes, and if necessary, optical fiber transmission inspection should be carried out.
1. Stretching: The terminal box should be able to withstand an axial stretching force of no less than 500N between it and a fiber optic cable, and no less than 5N between it and any wiring tail fiber.
2. Flattening: Each side of the terminal box body should be able to withstand a vertical static pressure of not less than 200N
3. Twisting: The terminal box should be able to withstand the twisting angle
