Devices with single-mode optical interfaces 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 according to EN 60825–1 +A11 +A2 requirements.

When working around devices with optical interfaces, 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.

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.
