Laser and LED Safety Guidelines and Warnings for Switches
EX Series switches, OCX1100 switches, and the XRE200 External Routing Engine 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 227
•
Class 1 Laser Product Warning on page 228
• Class 1 LED Product Warning on page 228
• Laser Beam Warning on page 229
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.
