For overly long or short fibers, coil them separately at the end. Before fiber coiling, the optical cable and pigtail should be pre-processed, and the optical cable and pigtail should be opened first. The key step is to calculate the reserved length and then splice the optical fiber. The success rate of optical fiber splicing is very important, because once the. Splice fiber optic cables follows these steps: stripping, cleaving, splicing, and coiling. When done right, splicing ensures minimal loss and long-lasting performance. This guide will walk you.
