Laser Safety Warnings for Class 1M Juniper Networks Devices


Juniper Networks devices 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

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.


    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.
