光纤接续方法及操作步骤详解（Optical fiber connection method and operation procedure detailed explanation） Optical fiber splicing is a meticulous work, especially in the aspects of surface preparation, welding, disc, fiber and so on, requiring operators to observe carefully, consider carefully, operation specifications. This article gives you a detailed description of the steps and practical techniques. Preparation of 1. end face The fabrication of fiber end faces includes delamination, cleaning and cutting. Qualified end face of optical fiber is necessary for welding, and the quality of end face influences the quality of welding directly. 1.1 stripping of fiber coating The stripping of optical fiber coating shall be controlled by three - tone stripping method, flat, steady and fast. Flat, that is, to maintain the fiber level. The left thumb and forefinger pinch fiber, make horizontal exposed length by 5cm, between the remaining fiber in the ring finger, little finger natural bent, to increase efforts to prevent slipping. Steady, that is, the stripping forceps should be firmly held. Fast fiber stripping speed, fiber stripping and fiber clamp should be vertical, in the direction of the tilt angle, and then use the jaw lightly clamped fiber with right hand, along the fiber axial force, push out, the whole process will go smoothly. 1.2 bare fiber cleaning Bare fiber cleaning, should follow the following two steps: 1) to observe whether the coating of the fiber peeling part is completely stripped, and if there is residual, it should be stripped again. If there is a small amount of coating which is difficult to be peeled off, it can be dipped by dipping the ball with proper amount of alcohol and gradually erasing. 2) will be torn into pieces of cotton sector level flat, dipped a little alcohol (two fingers to pinch without overflow is appropriate), folded into the shape of V, held to cover fiber stripping, along the fiber axis to wipe a success, a piece of cotton with 2 to 3 times to c
