iiiNoticeSafety InformationCLASS 1 LASER TRANSCEIVERSThe 9G429-02 is a Class 1 Laser ProductThe 9G429-02 uses a Class 1 Laser transceiver. Read the following safetyinformation before installing or operating these adapters.The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. Thiscontrol loop eliminates the need for maintenance checks or adjustments. The output is factory set, anddoes not allow any user adjustment. Class 1 Laser transceivers comply with the following safetystandards:• 21 CFR 1040.10 and 1040.11 U.S. Department of Health andHuman Services (FDA).• IEC Publication 825 (International Electrotechnical Commission).• CENELEC EN 60825 (European Committee for ElectrotechnicalStandardization).When operating within their performance limitations, laser transceiver output meets the Class 1accessible emission limit of all three standards. Class 1 levels of laser radiation are not consideredhazardous.Laser Radiation and ConnectorsWhen the connector is in place, all laser radiation remains within the fiber. The maximum amount ofradiant 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 theoptical port. The maximum radiance from the optical port (under worst case conditions) is 0.8 W cm-2or 8 x 103 W m2 sr-1.Do not use optical instruments to view the laser output. The use of optical instruments to viewlaser output increases eye hazard. When viewing the output optical port, power must be removedfrom the network adapter.
