Laser Safety Compliance Requirements
The SFF-PGG-2125-SW/LW is designed and certi-
fied as a Class 1 laser product. If the power supply
voltage exceeds 4.0 volts, the transceiver may no
longer remain a Class 1 product. The system using
the SFF-PGG-2125-SW/LW must provide power
supply over voltage protection that guarantees the
supply does not exceed 4.0 volts under all fault con-
ditions.
Caution:
Operating the power supply above 4.0V or
otherwise operating the SFF-PGG-2125-SW/LW in
a manner inconsistent with its design and function
may result in hazardous radiation exposure, and
may be considered an act of modifying or new man-
ufacturing of a laser product under US regulations
contained in 21 CFR(J) or CENELEC regulations
contained in EN 60825. The person(s) performing
such an act is required by law to recertify and
reidentify the product in accordance with the provi-
sions of 21 CFR(J) for distribution within the United
States, and in accordance with provisions of CEN-
ELEC EN 60825 (or successive regulations) for dis-
tribution within the CENELEC countries or countries
using the IEC 825 standard.
ESD Notice
It is advised that normal static precautions be taken
in the handling and assembly of the SFF-PGG-
2125-SW/LW to prevent damage and/or degradation
which may be introduced by electrostatic discharge.
