Optical Device Maintenance
Any contamination of the fiber connection can cause failure of the component or failure of the whole
system. A particle that partially or completely blocks the core generates strong back reflections, which
can cause instability in the laser system. Inspection, cleaning, and reinspection are critical steps to take
before making fiber-optic connections.
