Laser and LED Safety Guidelines and Warnings for J-EX Series Switches
J-EX Series switches are equipped with laser transmitters, which are considered a Class 1
Laser Product by the U.S. Food and Drug Administration and are evaluated as a Class 1
Laser Product per EN 60825–1 requirements.
Observe the following guidelines and warnings:
• General Laser Safety Guidelines on page 165
•
Class 1 Laser Product Warning on page 165
•
Class 1 LED Product Warning on page 166
• Laser Beam Warning on page 166
General Laser Safety Guidelines
When working around ports that support optical transceivers, 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.
