How to use fiber optic splice closure?

Fiber preparation

1. Remove the outer sheath of the optical cable, (if any, remove the shielding and armor), and then remove the wrapping layers until the loose tube is exposed. For the specific method, please follow the standard method recommended by the optical cable manufacturer. The preparation length is 3m.

2. Clean the loose tube and the reinforced core sheath with detergent, remove the excess filling tube, and polish the outer sheath of the optical cable with a length of 150mm with the provided sandpaper.

Optical cable installation

1. Select the sealing ring with the smallest inner diameter according to the outer diameter of the optical cable, and put the two sealing rings on the optical cable.

2. Put the optical cable into the corresponding hole.

3. Connect the shield and ground.

4. Wrap the self-adhesive sealing tape between the two sealing rings so that the sealing tape is wound to be flush with the outer diameter of the sealing ring to form a sealed end of the optical cable.

5. Press the sealed end of the optical cable into the cable entry hole.

6. Use a hose clamp to pass through the fiber optic cable reinforcing rib fixing seat and the cable core bracket, and fix the fiber optic cable on the base of the connector box. Tighten the hose clamp screw until the hose clamp is tightened.

7. Tie a nylon cable tie on the optical cable and cut off the excess length.

8. Please use plugs to seal the other unused optical cable holes. Sealing tape is also wrapped around the plug, the requirements are the same as 5.2.4.

9. Wrap the reinforcing member on the countersunk screw of the splice tray support and press it tightly.

Fiber connection

1. Prepare the optical fiber to be coiled 1.5 times after the winding, and then coil all the remaining fibers in the box.

2. Use a single-core buffer tube for single-core fiber loading, and use a ribbon buffer tube for ribbon-shaped fiber loading. Tie tightly with nylon cable ties at the entrance of the splice tray.

3. Connect the two (band) optical fibers according to the specified method, and the connector should be inserted into the slot of the splicing unit, and the excess length should be coiled in the disc.

4. Cover the splice tray and press to make it snap into place.

5. According to the required capacity of the splice box, determine the number of splice trays superimposed on the splice tray. The superposition type of the splice tray must meet the requirements of the optical fiber connector to be inserted into the splicing unit and inspection and maintenance. For every two fusion splice trays, six holes on the rubber folds can be clamped to each of the three convex twists on the upper and lower trays; four rubber folds, two symmetrical positions on both sides of the tray, such as stacking five For the splice tray, according to the above method, buckle the two-layer plate and the three-layer plate, buckle the three-layer plate and the four-layer plate, buckle the four-layer plate and the five-layer plate, and so on, the five plates are stably stacked together . When it is necessary to observe or maintain the welding condition of a certain layer of disk, only need to remove the two folds of the upper layer of the single side of the disk, and the welding disk can be opened.
