Any visible bubble means high splice loss. Cause: Contamination on one or both fiber end-faces. Most often skin oil from handling, dust from the work environment, or coating residue not fully stripped. Fix: Cut back, re-strip, re-clean with 99% IPA, re-cleave, re-splice. Fiber optic pigtails are used to connect fiber optic cables using fusion or mechanical splicing. What is a mechanical splice? What is a fusion splice? Why splice? Fiber splicing is one way to join two optical fibers together so the light energy from one optical fiber can be transferred to another. The most common Fusion Splicing Problem is dust. Poor fiber splicing, on the other hand, can lead to performance issues and increased maintenance costs. This guide breaks down the fundamentals of optical fiber splicing, compares. After completing a splice, you notice a small dot or bubble at the splice point on the screen image. The fiber appears fused, but a visible imperfection is present exactly where the two fibers were joined.
