How to use Huawei s intelligent fiber optic welding tray

Huawei's intelligent fiber optic welding tray integrates fiber splicing, coiling, and optical splitting, and should be installed, coiled, and spliced according to precise specifications for optimal performance.Installation of the Fiber Management TrayMounting Location: Place the tray on a wall or ceiling capable of supporting at least four times the total weight of the tray, device, and mounting bracket. Avoid installing between T-rail brackets and AP mounting brackets if using ceiling tiles ( ).Mounting Hardware: Use screws of proper specifications (e.g., GB9074.8-88-M3XL, L ≥ 15 mm) and expansion screws to secure the tray. Ensure tightening torque does not exceed 3.5 N·m to prevent damage ( ).Tray Orientation: Ensure the tray is level and accessible for fiber routing and splicing.Fiber Routing and CoilingFiber Entry: Route the optical fiber into the tray and begin coiling clockwise. The tray includes a coiling storage area designed for orderly fiber management ( ).Coiling Specifications:Maximum coiling length: 4 m for 2 mm diameter fibers.Pigtail coiling: 0.75 m if unstripped (3 mm diameter), 1 m if stripped.Coil fibers layer by layer, securing near the fiber splicing rod as needed ( ).Fiber Exit: Route the fiber out of the tray, leaving a proper length for connection to the AP. Adjust excess fiber by loosening the last coil or routing around the splice rod and securing with foam adhesive ( ).Splicing ProcedurePreparation: Cut fibers to the appropriate length and strip protective coatings. Ensure fibers are clean and free of debris ( ).Splicing: Use a fiber optic splicer to join fibers in the splice area of the tray. The tray may include splicing grooves arranged linearly for organized splicing ( ).Protection: Apply heat shrink tubing (recommended 3.8 mm x 40 mm) over spliced fibers to protect the joint ( ).Optical Splitter IntegrationMounting Port: The tray includes a mounting port in the optical splitting area. Adjust the support structure to fit the optical splitter securely ( ).Component Adaptation: The tray can accommodate splitters of different sizes and specifications without changing components, allowing flexible deployment ( ).Best PracticesAlways coil fibers carefully to avoid bending below the minimum bend radius.Use foam adhesive or clips to secure excess fiber and prevent movement.Verify that the fiber length at the outlet is sufficient for AP connection without tension.Gradually deploy components in live networks to match service volume and avoid material shortages ( ). By following these steps, Huawei's intelligent fiber optic welding tray can be effectively used for fiber splicing, coiling, and optical splitter integration, ensuring reliable network performance and ease of maintenance.
