Laser/LED Safety

An optical single-mode transmitter uses a small laser to transmit the light signal to the network ring.
Keep the transmit port covered whenever a cable is not connected to it. Although multimode transceivers
typically use LEDs for transmission, it is good practice to keep open ports covered and avoid staring into
open ports or apertures. The single-mode aperture port contains a laser warning label, as shown in
Figure
These warnings apply to SPAs and SFP modules that transmit signals via an optical carrier signal.

Place a removed board component-side-up on an antistatic surface or in a static shielding container.
If you plan to return the component to the factory, immediately place it in a static shielding
container.
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Never attempt to remove the printed circuit board from the metal carrier.
