Optical fiber end face processing

fiber end face quality directly affects the laser output power and fiber laser optical coupling efficiency. Optical fiber end face processing preparation, also known as the optical fiber end face is the key process in optical fiber technology, mainly including peeling, clean and cut the three links. 1, optical fiber coating layer peel to remove except for the optical fiber coating layer is the first step on the fiber end face processing. Miller clamp for strip can be used. When using miller clamp strip, left thumb and index finger pinched optical fiber, the length is 5 cm, more fiber in the ring finger and little finger between natural bending, in order to increase strength, prevent slippage, stripping pliers should be vertical, and the fiber direction incline on a certain Angle, and then gently with jaw stuck fiber, right hand hard, then along the fiber axial flat out, the whole process to natural, strive for a successful; 2, cleaning observation on the surface of the optical fiber cladding fiber stripping section of the cladding is removed, if there is residue must be removed, if there is a little difficult to removal of the coating layer, usable cotton ball dipped in a moderate amount of alcohol, impregnation, and erase. Cotton wool to tear into level flat fan-shaped pieces, with a little alcohol ( With two refers to knead without overflow advisable) Into V, and clamp strip cladding fiber, along the fiber axial to wipe, 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 secondary pollution on the surface of fiber cladding. 3, optical fiber end face of cutting fiber cutting is the most critical step in preparation of optical fiber end face, precision quality of optical fiber cutting knife is a foundation, strictly regulate the scientific operation is the guarantee. Using optical fiber cutting knife for operation, the first thing to clean cutter blade, the V groove of the fiber placement, and positioning clamp, and adjust the cutter location to make it smooth. Cutting action to smooth and natural, not heavy, don't worry, to avoid the broken fiber, bevel, burr and cracks bad end. Clean and cut the time should be on the surface of the optical fiber to connect, an interval is too long, especially in the preparation of end face do not have on the foul air. Moves to should take put down gently, prevent the brush with other objects touch the end of the optical fiber secondary damage.
