White flashes appear during discharge from the fiber optic fusion splicer

Quick triage: When splices start failing, work through these checks in order: (1) re-clean the fiber, (2) advance/replace the cleaver blade, (3) clean the v-grooves, (4) run arc calibration, (5) verify the splice program matches the fiber type, (6) inspect or replace.

Fiber optic fusion splicers require precise operation. Even a minor error can lead to significant signal loss or faulty splices. The following describes the most common problems, their quick diagnosis, and recommended solutions. Fiber contamination Alignment error messages. 1 dB). The fusion splicer flags every kind of problem with its own visual signature, but the troubleshooting is the same: identify the defect, find the root cause, fix it, and re-splice. Quick triage: When splices start failing, work. High splice loss occurs when the fusion between two fibres does not achieve proper core alignment, resulting in excessive optical signal attenuation. The root causes typically include: To resolve this, first check the fibre ends. Clean V-groove and fiber clamp.
