Ftth Box is used for outdoor, corridor or indoor connection trunk cable and wiring cable interface equipment. Its internal metal plate with Q235 cold-rolled plate, the thickness of not less than 1.2mm, the surface galvanized treatment, the box up and down the installation board using Q235 cold-rolled plate, the thickness of not less than 2mm, galvanized after the spray treatment. Outdoor type is also equipped with pole to install iron pieces, the use of stainless steel or iron accessories hot galvanized treatment.
The work unit of the ftth box includes cable fixing device, grounding device, fiber splicing disk, optical fiber connection and distribution device, optical splitter, pigtail connector parking area, leather line cable fixed area. This product must be stored in a well-ventilated, dry warehouse with no corrosive gas around it.
For ftth box, the following requirements are required: The protective grounding of ftth box must have obvious grounding mark. The grounding device must be connected with the metal reinforcement core and metal tidal layer and armored layer of the cable. The cross-sectional area of the grounding wire must be not less than 6 square millimeters. The resistance between the body and the frame is not less than 3000V.
Ftth box's case must have good resistance to corrosion and resistance to aging. The top surface of the box must be capable of withstanding a vertical pressure of not less than 500 N, and the enclosure door must be capable of withstanding a vertical pressure of not less than 100 N at the outermost end of the door. After unloading the load, the box must be free of damage and permanent deformation. When the fiber optic is introduced, the ordinary cable must be able to withstand the axial tension of not less than 500N; self-supporting butterfly cable must be able to withstand not less than 200N axial tension. After the tensile, torsion test to check the fixed fiber optic, the fiber optic must be no loose, damage phenomenon.
In addition, the ftth box must be marked, indicating the implementation of the standard number, product model, name, trademark, production unit, the date of shipment. The connector of the ftth box must be marked with a trademark or manufacturer. Fiber splicing discs within the ftth box must be marked by a trademark or manufacturer.
