• 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

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

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.
