光缆熔接（Fiber optic cable welding） 1 face preparation The preparation of optical fiber ends includes stripping, cleaning and cutting. Qualified optical fiber ends are necessary for welding Condition, face quality directly affect the quality of welding. 1.1 stripping of fiber coated layer The stripping of the fiber coated layer should be mastered flat, stable and fast three - word fiber stripping method. Ping means holding the fiber flat. The left hand thumb and forefinger pinch the fiber, make it into a horizontal shape, the length of the exposed length is 5cm, and the remaining fiber is naturally bent between the ring finger and the small finger to increase the strength to prevent slipping. Stabilisation means that the stripper should hold firmly. Fast peel fiber, namely peel fiber clamps should be vertical, and the optical fiber direction on the tilt Angle, and then gently with jaw stuck fiber right hand, and then hard, along the fiber axial flat out, the whole process to natural, coherent whole. 1.2 naked fiber cleaning The cleaning of bare fiber should follow the following two steps: 1) observe whether the coating of the fiber removal is all removed, and if there is any residual, it should be restripped. If there is a very small amount of not easy to strip off the coating, can use the ball to dip in the right amount of alcohol, while soaking, gradually erasing. 2) cotton tore into flat fan-shaped pieces, with a little alcohol (with two fingers pinched no overflow advisable), folding into a V shape, clamp with strip cladding fiber, along the fiber axis is wiped, strive for success at a time, a piece of cotton USES to change in time after 2 ~ 3 times, each time to use the different parts of the cotton and level, it can improve the utilization rate of cotton, and prevent the fibers two times pollution. 1.3 cutting of bare fiber The cutting of bare fiber is the most critical part in the preparation of optical fiber ends. The precision and fine cutting tool is the foun
