SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
THE FAST ETHERNET INTERFACE MODULE, FDDI PORT INTER-
FACE MODULES, AND ATM INTERFACE MODULES USE
CLASS 1 LASER TRANSCEIVERS. READ THE FOLLOWING
SAFETY INFORMATION BEFORE INSTALLING OR OPERATING
THESE ADAPTERS.
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.
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 103W m2sr-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.
