The size of the loss is a very important technical indicator of the optical fiber fusion splicer. The lower the loss, the higher the precision of the machine, which can support longer distance fusion splicing. The more perfect the fusion point, the longer the service life. 1. The fiber cleaver cutting angle of the fiber is very important. At present, most of the optical fiber fusion splicers are fully automatic fusion splicing. So you can set the splicing mode to semi-automatic, and let the fiber push to the screen to display the angle. If the angle meets the standard, press the splice button. If it does not meet the standard, you can re-cut the fiber. For the best fusion splicing effect, it is recommended that the fiber cutting angle be around 0.5°. 2. The splicing machine performs discharge correction on a regular basis. Discharge correction is mainly for the machine to adapt itself to the working environment and fine-tune itself, so that the discharge voltage, current and other aspects of the optical fiber fusion splicer are most suitable for the working environment at that time, so as to achieve the best fusion splicing state. Doing discharge correction every time will help the machine to maintain the best welding state, which can effectively reduce the large loss caused by changes in external temperature and humidity. 3. Regularly replace the electrode rod The discharge of welding is mainly through the work of the electrode rod. Long-term use will cause the electrode rod to age slowly. Generally, the life of the machine electrode rod is about 3000 cores, and some better machine electrode rods can use 3000 to 6000 cores. Therefore, after the machine is used for a period of time, it is necessary to pay attention to the loss of the lower electrode rod and replace it in time to avoid the problem of increased loss
