Bubbles are always present in multimode fiber optic fusion splicing

Bubbles are always present in multimode fiber optic fusion splicing

Bubbles are not always present in multimode fiber fusion splicing; they occur due to contamination or improper fiber preparation.Understanding BubblesA bubble in a fusion splice appears as a dark circular or oval void within the splice region and indicates high splice loss. These bubbles form when contaminants on the fiber end-face, such as dust, skin oil, or coating residue, are vaporized by the fusion arc and trapped in the molten glass as it solidifies . They are defects, not a normal feature of multimode fiber splicing.CausesContaminated fiber end-faces: Dirt, dust, or oils transferred during handling can create bubbles .Improper cleaving: Tilted or rough end-faces can trap air or debris, leading to voids .Dirty cleaver blades: Residue on the cleaver can transfer to the fiber end, causing bubbles .Splicer settings: Incorrect arc energy or misalignment can exacerbate bubble formation .Prevention and FixesClean fibers thoroughly using 99% isopropyl alcohol and lint-free wipes before splicing .Re-cleave fibers to ensure smooth, perpendicular end-faces .Check and maintain splicer electrodes and calibration to ensure proper arc energy .Avoid touching fiber ends with bare hands to prevent oil contamination .Key TakeawayBubbles are not an unavoidable feature of multimode fiber fusion splicing. With proper cleaning, precise cleaving, and correct splicer settings, splices can be bubble-free, resulting in low-loss, high-quality connections .
