Safety Information
Class 1 Laser Transceivers
The single mode interface modules use Class 1 laser transceivers.
Read the following safety information before installing or operating these modules.
The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the
need for maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment. Class 1 Laser
transceivers comply with the following safety standards:
• 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.
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
W m
2
sr-1.
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 network adapter.
Safety Compliance
Warning: Fiber Optic Port Safety
Avertissment: Ports pour fibres optiques - sécurité sur le plan optique
Warnhinweis: Faseroptikanschlüsse - Optische Sicherheit
When using a fiber optic media expansion module, 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 (Tramsmission) 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.
