Optical fiber cleavers are used in relatively harsh environments, so correct operation and maintenance are of great significance to ensure the service life of the cleaver and the quality of fiber cleaving. The D12 fiber cleaver of Shenhuo Seiko Nanjing Communication Technology Co., Ltd. is a compact and easy-to-operate fiber cleaver, which can be used to cut single-mode, multi-mode, dispersion and non-zero dispersion single-core silica fiber, which is widely used in optical fiber communication construction among. 1. Exploitation and cutting of optical fibers 1) Open the pressure lever and small pressure plate, and push the slider with the blade to the side in front of you. 2) Strip the fiber coating layer about 30mm long, and wipe the bare fiber with a cotton ball dipped in anhydrous alcohol. 3) Align the edge of the fiber coating with the appropriate scale on the cutting knife ruler (10~20mm), 4) Put the fiber into the fiber guide groove with the left hand, and ask the bare fiber to be placed straight on the rubber pad. 5) Close the small pressure plate and pressure rod, push the slider with the blade, so that the blade cuts the lower surface of the fiber, and slides freely to the other side to cut the fiber. Be careful not to use too much force. 6) Hold the cutting knife with the left hand, and open the pressing rod with the right hand. 7) Pinch the fiber with your left hand, open the small pressure plate with your right hand, and carefully remove the fiber with the cut end face. Note: The neat fiber end face should not touch other objects. 2. Judgment of fiber cutting quality The quality of fiber cutting has an important influence on the loss of fiber splicing. The cutting angle of the end face of the D12 fiber cleaver should be no more than 0.7°, and the end face of the fiber cleaving knife should be flat, without burrs, and without core defects. 3. Blade adjustment and replacement During the fiber cutting process, if the fiber cutting quality deteriorates and the fiber is continuously cut, it is necessary to adjust the height or position of the blade in time. If the blade is found to be severely worn, please replace the blade 4. Cleaning and maintenance Since the fiber cleaver is a precision instrument and its use environment is relatively harsh, it is particularly important to clean and maintain it correctly. When it is found that the cutting quality of the cleaver deteriorates or the optical fiber is not easy to cut, a large part of the reason is that dust or debris has fallen into the cleaver blade, upper and lower pressure plates, guide grooves, etc., so frequent cleaning and maintenance are required. Specific steps are as follows: 1) Use a cotton swab dipped in anhydrous alcohol (other organic solvents cannot be used), and wipe the upper and lower platens in one direction. 2) Dip a cotton swab with anhydrous alcohol and rotate the blade in one direction. 3) Use a cotton swab dipped in anhydrous alcohol to clean and wipe the guide groove.
