An improper cleaving angle can lead to uneven fibre surfaces, which makes it difficult for the fusion splicer to align the fibres. The cleaver should produce a perpendicular cut to the fibre to ensure proper alignment during splicing. Poor cleaving is one of the most common causes of poor splice results when using a fusion splicer. When cleaving isn't done correctly, it can lead to gaps, misalignment, or even an incomplete splice, which can compromise the integrity of your network. But fear not; there are simple troubleshooting. The performance of a fiber optic splice is determined by a number of factors, including the quality of the fiber, the cleanliness of the splice, and the techniques used to make the splice. Intrinsic factors, such as the refractive index of the fiber, are those that are inherent to the fiber itself. To counteract these errors, technicians can go through the following troubleshooting checklists: Perform an Arc Test: Before splicing, it's important to perform. One of the most frequent complaints among technicians is unexpectedly high splice loss. The root causes typically include: To resolve this, first. The fiber diameter appears reduced where the two fibers were joined. A “too thin” splice is typically caused by excessive stretching of the molten glass during the arc.
