T640 General Laser Safety Guidelines
Devices with single-mode optical interfaces are equipped with laser transmitters, which
are considered 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.
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.
