7.0 Warnings - Cleaning the Optical Fiber Cable Ends
1) Caution: Do not look directly at the end of the fiber optic cable when disconnected.
Doing so may cause serious eye injuries from the laser energy.
2) Do not scratch the optical fiber cable end. Wipe the surface with alcohol using a dust-free
cloth. Next, wipe it with a dry dust free cloth, and then quickly wave the fiber end back and
forth in the air. Do not blow air onto the fiber to dry it. Doing so may cause dust to
permanently scratch the fiber cable end.
