LASER SAFETY
This multimode Gigabit Ethernet transceiver is a Class 1 laser
product. It complies with IEC 825-1 and FDA 21 CFR 1040.10
and 1040.11. The transceiver must be operated under recom-
mended operating conditions. Because the transceiver design
is designed to be inherently eye safe, it does not require open
fiber control thus eliminating complex electronics or mechanics.
Caution
The use of optical instruments with this product will increase
eye hazard!
General Restrictions
Classification is valid only if the module is operated within the
specified temperature and voltage limits. The system using the
module must provide power supply protection that guarantees
that the system power source will cease to provide power if the
maximum recommended operation limit or more is detected on
the +3.3 V at the power source. The case temperature of the
module must be in the temperature range given in the recom-
mended operating limits. These limits guarantee the laser
safety.
Usage Restrictions
The optical ports of the modules shall be terminated with an
optical connector or with a dust plug.
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)).

Mounting Studs
The mounting studs are provided for transceiver mechanical attachment to the cir-
cuit board. They also provide an optional connection of the transceiver to the equip-
ment chassis ground.
The holes in the circuit board must be tied to chassis ground.
