Laser Safety
Danger!
Personnel handling fiber optic cables must be trained for laser safety.
Danger!
Optical Fibers emit invisible laser radiation. Avoid direct exposure to the beam.
Never look into the end of a Fiber or into a Fiber connector on a cable or a device.
Permanent eye damage or blindness can occur quickly from laser radiation.
