VI. Installation

 

1. Optical cable stripping:
Loop through cable (unbroken cable): mark the cut point of the sheath, strip about 180 cm or according to the relevant requirements.

Broken cable: Peel off a pair of optical cables to be connected, remove the cable protective layer from the mark, peel off 120cm of sheath, and maintain the internal integrity

2. Open the port: According to the requirement, use a saw to cut the cable port.

3. Put the heat-shrinkable tube on the peeled cable, and introduce it into the closure.

4. After the optical cable enters the box, lock it with a hose clamp, fix the reinforced column with a presser, and introduce the docked cables into the splicing tray for splicing.

5. Wrap the junction between the optical cable and the heat shrink tube with tin foil to avoid overheating and damaging the cable. Heat the cable with a torch until the heat shrink tube is completely attached to the port. Wait till it cools naturally (note: when heating the oval port, separate the heat shrink tube with a dividing clip)

6. Cover installation: After the operation is completed, place a sealing ring in the groove of the base, put the cover onand lock them with a plastic clamp.
7. Wall & pole mounting operation:
Wall mounting: Lock the box tightly with the hoop, and finally connect it to the wall with expansion bolts

Pole mounting: Use a pole connector to connect the box body to the column body with a hoop
