Drop Cable Fusion Splicing Parameter Settings

Optimizing drop cable fusion splicing requires precise fiber preparation, correct splicer settings, and proper alignment to achieve low-loss, reliable splices.Fiber PreparationStripping and Cleaning: Remove the fiber coating carefully using a stripper suitable for the fiber diameter (typically 250µm for bare fibers and 900µm for coated fibers). Apply uniform pressure to avoid microfractures. Clean the fiber ends with lint-free wipes soaked in 99%+ isopropyl alcohol, wiping from the coating edge to the cleave tip in a single stroke to prevent contamination .Cleaving: Use a precision fiber cleaver to produce a flat, perpendicular end face. Align the fiber in the cleaver using the markings (typically 10–16 mm of stripped fiber) and ensure the bare fiber is straight in the V-grooves . A cleave angle below 1° is recommended to minimize splice loss .Splicer SettingsFiber Type Selection: Confirm the fiber type (single-mode or multi-mode) and select the corresponding splice mode on the fusion splicer .Arc Calibration: Perform a quick optimization or arc calibration daily or when environmental conditions change, or when splicing different fiber types .Alignment Method: Use core alignment (optical core alignment) for single fibers to achieve low splice loss (
