Often from inadequate cleaning or from fiber that touched a surface between cleaving and loading into the splicer. Fix: Re-clean and re-cleave both fibers. Fiber optic fusion splicers require precise operation. 1 dB). The factors that cause this fault can be analyzed from the following points: (1) Is the external power supply normal? (2) Is the external switch normal? (3) Can you see the motherboard information when you turn it on? If not, it may be that the motherboard is damaged. Stuck, it may be a program. The fusion splicer flags every kind of problem with its own visual signature, but the troubleshooting is the same: identify the defect, find the root cause, fix it, and re-splice. Very often, these issues are not caused by faulty equipment, but by small gaps in technical understanding or by the difficulty of diagnosing a problem under changing field conditions.
