General Laser Safety Guidelines
When working around the services gateway, observe the following safety guidelines to prevent eye injury:
Do not look into unterminated ports or at fibers that connect to unknown sources.
Do not examine unterminated optical ports with optical instruments.
Avoid direct exposure to the beam.
Warning Unterminated optical connectors can emit invisible laser radiation. The lens in the human eye focuses all the laser power on the retina, so focusing the eye directly on a laser source—even a low-power laser—could permanently damage the eye.
