A Guide to The  Junction Box

Introduction:

This product is used to connect the distribution cable and the incoming cable is widely applied in communication, network systems, CATV cable TV and so on. It adopts scientifically formulated engineering plastic and be shaped by injection molding, anti-aging, anti-corrosion, flame retardant, waterproof, anti-vibration and anti-shock effects. It can effectively prevent optic fibers from the influence of the outdoor environment.

Dome-to-base design; up to 8 pieces splice trays with excessive loose buffer storage basket, hinge for access of any splice without disturbing others trays; Fast and reliable sealing performance, easy to package multiple times. With a lightning protection grounding device, it can be applied in overhead, pole/ wall mounting or directly buried.

Installation Guidance

1. Cut the ports need to guide-in cable.

2. Put the cable through the heat-shrink tube

3. Remove the sheath of the cable and clean it. Cut the strengthen member to 5cm length. Put it through the attach screws and bend it to fix on the screw. Then tighten the screw.

4. Remove the loose tube of the cable and clean the bare fibers. Put them through the transparent PE tube. Using PVC tape to wrap the end of the PE tube and cable.

5. Wind the excessive loose buffers in suitable cycles and put in the storage basket.

6. Coiling the optic fibers in the splice trays as above picture from the bottom tray to the top one. Fusion the joints and shrink the protective tubes and fix them in the tray. And put on the tray lid.

7. Use the Velcro strip to bind the trays.

8. Using abrasive strip to rough the surface of the cable sheath and ports slightly.

9. Clean the cable surface and ports.

10. Move the heat-shrink tube to cover the base port and the cable. Mark the tube end on the cable and stick the aluminum film on it. The blue line of the film shall at the same position of the marked place. ( Edge which closes to the blue line shall be in the tube. Other side out of the tube.) Using a blunt tool to even the film tightly stick to the cable. Heat the tube to shrink to seal from the direction of the red arrow slowly. (If to guide 2 cables in the oval port, use branch off clips to separate the cables, heat the branch off clip at the meantime to seal the space.)

11. Heat the round ports follow the same step as the oval port.

12. Close the closure with the clamp.

13. Choose the suitable mounting kits for the different installation environment.
