1. Stripping and fixing the optical cable 1. Open the connector box, confirm whether the accessories are complete, and check the sealing method of the connector box; 2. Cut off at least 0.5 meters of the optical cable that needs to be connected; 3. Strip the optical cable to a length of 1.3 meters (Probably from the middle finger of the left hand to the right shoulder), use alcohol cotton balls or cleaning paper to remove the oil on the bundle tube; 4. Determine the length of the reinforcing core according to the length in the connector box; 5. Polish the outer sheath of the optical cable with sandpaper, and use the connector to Wrap the tape in the box; 6. First fix the reinforcing core (make a return bend of no more than 2cm), and then fix the optical cable; 7. The tube bundle is left natural and can be freely expanded and retracted, and a transition hose is installed according to the situation. .
2. Optical fiber splicing work 1. Open the stripping tube, use alcohol cotton balls to remove the oil stain on the optical fiber, pre-roll, and finally put the hot melt tube on; 2. Use wire stripping pliers to strip off the optical fiber coating Coating (40mm); 3. Wipe with a semi-dry alcohol cotton ball or dust-free paper. It is required to perform a "cross" wipe, and after wiping, there will be no stains or water stains on the optical fiber; 4. The length of the optical fiber cutting, according to the fusion splicer The length of the V-shaped groove is determined (14-16mm); 5. The cutting knife must be placed stably, and the cut optical fiber cannot touch any object to prevent the cut from breaking and secondary pollution; 6. The fusion splicer must perform discharge calibration before splicing. Observe the welding screen and pay attention to whether the welding spark is normal and whether the fiber core is aligned and connected; 7. After the fiber welding is completed, put the welding point into the hot melt tube and perform hot melting.
It is required that there are no stains in the hot melt tube, the length is uniform, and there is no deformation or bubbles; 8. After the optical fiber is connected, it is fixed in the slot in the order of the chromatogram; 9. The hot melt tube is placed in the bundle The opposite side of the tube is fixed, and the optical fiber is in a cross shape, making a wide circle; 10. After the hot melt tube is fixed, the remaining optical fiber is coiled in an "8" pattern in the order of first left and then right, without extrusion or warping. .
3. Box body installation 1. Use alcohol cotton balls to clean the sealing ring and side groove of the joint box; 2. Make a plug according to the accessories in the joint box; 3. Fasten the joint box, and the box body can naturally It has fallen and there is no bulge or skew; 4. Tighten the screws diagonally. The tightening requirement is to tighten it twice after 10 minutes; 5. After the installation of the connector box is completed, pull one end of the optical cable and shake it.
Confirm that the firmware is not loose; 6. The overhead connector box falls within 2M of the straight pole. Directly buried optical cable connector boxes are not allowed to be placed in ponds or solid rock areas. Pipe connector boxes are placed on brackets. Avoid major traffic intersections.
