The arc is interrupted due to lack of power. Check the battery charge status and cycles in the device menu. Replace the battery when it loses more than 30% of its. When fusion splicing in the field, a number of issues can arise, causing equipment errors and faulty splices, leading to high splice loss. Very often, these issues are not caused by faulty equipment, but by small gaps in technical understanding or by the. Splicing is required to create a continuous path for light transmission from one fiber to another. Two different methods exist for splicing fibers: Typical splice loss values (the measure of loss in optical power across the splice point) are usually lower for fusion splices (typically less than 0.
