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:

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.
WARNING: Class 1 laser product.
