SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
THE DELF3-UI FAST ETHERNET INTERFACE MODULE, DEL05-UI
FDDI PORT INTERFACE MODULE, AND DEL29-UI ATM PORT INTER-
FACE MODULE USE CLASS 1 LASER TRANSCEIVERS. READ THE
FOLLOWING SAFETY INFORMATION BEFO R E
INSTALLING OR OPERATING THESE MODULES.
The Class 1 laser transceivers use an optica l feedback loop to maintain Class 1 op eration limits. This
control loop eliminates the need for maintenance check s or adjust men ts. The out p ut is fac to ry set , and
does not allow any user adjustment. Class 1 laser transceivers comply with the following s afety
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 Electrote chnical Standardization).
When operating within their performance limitations, laser transceiver output meets the Cla ss 1
accessible emission limit of all three standards. Class 1 levels of laser radiation are not consider ed
hazardous.

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 tra nsceiver 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 103 W m2 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 outp ut opt ical port, power must be
removed from the network adapter.
