Fiber Closure Distribution Box

The Fiber Closure wiring box is the component that forms the EPON and GPON networks. It is used to place passive devices connected to the OLT and ONU. The device can be used to distribute downlink data and focus on uplink data. The splitter has an upstream optical interface and a plurality of downstream optical interfaces, which are generally used for fiber splitting of the optical fiber core of the loop terminal, and have the functions of optical fiber splicing, terminal, jumper, and wiring machine fiber.

The cabinet of the Fiber Closure distribution box should have good corrosion resistance and aging resistance and should be able to prevent electrical damage. The material should be non-toxic, non-corrosive and will not cause side effects on the human body and other equipment. The door lock should adopt an anti-theft structure and have a good loss prevention function. In order to ensure the safety of the equipment inside the box, the safety of the door should also be configured to increase the padlock of the pendant and the hole.

The material used to make the exterior of the cabinet shall be cold-rolled steel sheet and shall have good physical strength and corrosion resistance and electrochemical reaction capability. After assembly, the metal does not see burrs, the structural parts are not twisted, the surface is smooth, the color is uniform, there is no trace of mechanical scratches, and the parts must not have obvious color. The surface of the coating should be continuous and uniform, consistent with the corresponding standard template.

The layout of the space inside the box should meet the requirements for laying the cable. The bend radius of the cable should be 20 times larger than the bend radius of the cable. Regardless of where the fiber is turned, the radius of curvature should be no less than 30 mm. And the cabinet should be set to protect the original grounding and have a clear grounding mark when protecting the ground.
