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

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.
