Class 1 Laser Product Warning | 375
Class 1 LED Product Warning | 375
Laser Beam Warning | 376
Juniper Networks devices are equipped with laser transmiers, which are considered a Class 1 Laser
Product by the U.S. Food and Drug Administraon and are evaluated as a Class 1 Laser Product per
IEC/EN 60825-1 requirements.
Observe the following guidelines and warnings:
General Laser Safety Guidelines
When working around ports that support opcal transceivers, observe the following safety guidelines to
prevent eye injury:
• Do not look into unterminated ports or at bers that connect to unknown sources.
• Do not examine unterminated opcal ports with opcal instruments.
• Avoid direct exposure to the beam.
LASER WARNING: Unterminated opcal connectors can emit invisible laser radiaon.
The lens in the human eye focuses all the laser power on the rena, so focusing the
eye directly on a laser source—even a low-power laser—could permanently damage the
eye.
Averssement Les connecteurs à bre opque sans terminaison peuvent émere un
rayonnement laser invisible. Le cristallin de l’œil humain faisant converger toute la
puissance du laser sur la réne, toute focalisaon directe de l’œil sur une source laser,
—même de faible puissance—, peut entraîner des lésions oculaires irréversibles.
