SAFETY INFORMATION
CLASS 1 LASER TRANSCEIVERS
THE DELHE-UA GIGABIT ETHERNET 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 chec ks or adjust me nts. T he outp ut is fa cto ry set , and
does not allow any user adjustment. Class 1 laser transceivers comply with th e following safety
standards:
• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).
• IEC Publication 825 (International Electrotechnical Commiss ion).
• CENELEC EN 60825 (European Committee for Electrote chnical Standardization).
When operating within their performance limitations, l as er transceiver output meets the Class 1
accessible emission limit of all three standards. Class 1 le vels of laser radiation are not considered
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 co nditions) is -12.6 dBm or 55 x 10-6 watts.
Removing the optical connector from the transceive r 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.
