Safety precautions for optical fiber splicing
1. The optical cable is spliced to avoid the traffic arteries. If it is unavoidable, it is necessary to work on the road. It is necessary to place warning signs and arrange for a special person to be responsible for monitoring. The welding equipment should be set in a hidden place beside the road. In case of rain and snow, there should be a special umbrella to support it to avoid the rain.
2. Before and after welding, the welding equipment must be kept clean, and the stains and garbage must be removed.
3. Before splicing, the direction of each optical cable must be clarified to prevent dislocation and crossing.
4. When welding, turn on the AC and DC power supply in time, and turn off the AC and DC power supply in time after welding.
5. The welding equipment should be placed in a safe, ventilated and dry room to prevent overheating and moisture.
6. Care must be taken to avoid scratching your fingers when operating the fiber cutter.
7. When cutting the fiber, clean up the fiber debris in time to prevent the fiber core debris from piercing the skin
8. After the welding machine heat shrinks the heat shrinkable tube, pay attention to the residual temperature of the heat shrinkable tube and the heating tank to avoid burns.

Construction and installation requirements of home optical cable
1. When laying the butterfly optical cable, the traction force when laying the household optical cable should not exceed 80% of the allowable tension of the optical cable; the instantaneous maximum traction force should not exceed 100% of the allowable tension of the optical cable, and the main traction force should be added to the strengthening member of the optical cable;
2. The minimum bending radius of the butterfly optical cable laying should meet the following requirements: the bending radius of the butterfly optical cable should not be less than 30mm during the laying process; the bending radius of the butterfly optical cable should not be less than 15mm after fixing;
When the butterfly optical cable is installed on the wall or overhead, the self-supporting butterfly optical cable can be used. The steel wire of the butterfly optical cable should be properly tightened and fixed firmly;
3. When the butterfly optical cable is installed on the wall or overhead, the self-supporting butterfly optical cable can be used. The steel wire of the butterfly optical cable should be properly tightened and fixed firmly;
4. The butterfly optical cable cannot be immersed in water for a long time, and is generally not suitable for direct laying in underground pipes;
5. The minimum bending radius of butterfly optical cable laying should meet the following requirements. During the laying process of optical cable, strict attention should be paid to the tensile strength and bending radius of the optical fiber, so as to avoid the optical fiber from being entangled, twisted, damaged and trampled; The bending radius of the optical cable should not be less than 30mm; the bending radius of the butterfly cable should not be less than 15mm after fixing;
6. When laying the butterfly-shaped optical cable, the entire optical cable from the optical distribution box to the user terminal must be reversed from the optical cable reel in a one-time reel and then laid out. It is forbidden to directly release it from the optical cable reel for construction. It is forbidden to have joints in the middle of the optical cable;
7. After the butterfly-shaped entry optical cable is laid and entered into the home, reserve 1.0m on one side of the fiber optic cable distribution box or optical distribution box, and reserve 0.5m on the side of the household information distribution box or optical fiber panel socket. The fixing devices of the butterfly drop cable into the fiber optic box and the split box should be managed one by one. Each butterfly drop cable should be coiled in an arc position, and cannot be pulled straight or angled, and must pass through the hook inside the box. Tie tightly with the cable ties, the binding should be natural and straight, without twisting, looping and other phenomena, and should not be squeezed by external forces and damaged by operation;
8. After the butterfly optical cable is laid, paste the label on the end of the butterfly optical cable of the optical distribution box (that is, 5cm away from the quick connector), and the paste must be standardized and firm;
9. When the butterfly-shaped optical fiber cable enters the box, the opening of the box must be properly blocked
