Optical Device Installation and Removal
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.
Cleaning Optical Devices
Refer to the Inspection and Cleaning Procedures for Fiber-Optic Connections document for information
on cleaning optical devices.
