Safety Information
CLASS 1 LASER TRANSCEIVERS
The 9F120-08, 9F122-12 and 9F125-08 are Class 1 Laser Products
The 9F120-08, 9F122-12 and 9F125-08 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.
