• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA). 
• IEC Publication 825 (International Electrotechnical Commission). 
• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).
• When operating within their performance limitations, laser transceiver output meets the Class 1  
accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered 
hazardous. 
SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
LASER RADIATION AND CONNECTORS
When the connector is in place, all laser radiation remains within the fiber. The maximum amount of 
radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10
-6
 watts. 
Removing the optical connector from the transceiver allows laser radiation to emit directly from the 
optical port. The maximum radiance from the optical port (under worst case conditions) is 0.8 W cm
-2
 
or 8 x 10
3

. 
Do not use optical instruments to view the laser output. The use of optical instruments to view laser 
output increases eye hazard. When viewing the output optical port, power must be removed from the 
switch.
WARNING: FIBER OPTIC PORT SAFETY

SÉCURITÉ SUR LE PLAN OPTIQUE
WARNHINWEIS: FASEROPTIKANSCHLÜSSE - 
OPTISCHE SICHERHEIT
When using a fiber optic port, never look at the transmit laser while it is 
powered on. Also, never look directly at the fiber TX port and fiber cable 
ends when they are powered on.
Ne regardez jamais le laser tant qu'il est sous tension. Ne regardez jamais 
directement le port TX (Transmission) à fibres optiques et les embouts de 
câbles à fibres optiques tant qu'ils sont sous tension.
Niemals ein Übertragungslaser betrachten, während dieses eingeschaltet ist. 
Niemals direkt auf den Faser-TX-Anschluß und auf die Faserkabelenden 
schauen, während diese eingeschaltet sind.
