Pin Description
Regulatory Compliance
EYE SAFETY
This laser based multimode transceiver is a Class 1 product. It
complies with IEC 60825-1 and FDA 21 CFR 1040.10 and
1040.11.
To meet laser safety requirements the transceiver shall be oper-
ated within the maximum operating limits.
Caution
All adjustments have been made at the factory prior to ship-
ment of the devices. No maintenance or alteration to the
device is required.
Tampering with or modifying the performance of the device
will result in voided product warranty.
Note
Failure to adhere to the above restrictions could result in a modifica-
tion that is considered an act of
“
manufacturing,
”
and will require,
under law, recertification of the modified product with the U.S. Food
and Drug Administration (ref. 21 CFR 1040.10 (i)).
