Laser and LED Safety Guidelines and Warnings for EX Series Switches
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 213
■ Class 1 Laser Product Warning on page 214
■ Class 1 LED Product Warning on page 214
■ Laser Beam Warning on page 215
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.
