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.

Warning
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments. Statement 1051
Waarschuwing Losgekoppelde of losgeraakte glasvezels of aansluitingen kunnen onzichtbare laserstraling
produceren. Kijk niet rechtstreeks in de straling en gebruik geen optische instrumenten rond deze
glasvezels of aansluitingen.
Varoitus Irrotetuista kuiduista tai liittimistä voi tulla näkymätöntä lasersäteilyä. Älä tuijota säteitä tai katso
niitä suoraan optisilla välineillä.
Attention Les fibres ou connecteurs débranchés risquent d'émettre des rayonnements laser invisibles à l'œil.
Ne regardez jamais directement les faisceaux laser à l'œil nu, ni d'ailleurs avec des instruments
optiques.
Warnung Unterbrochene Fasern oder Steckerverbindungenkönnen unsichtbare Laserstrahlung abgeben.
Blicken Sie weder mit bloßem Auge noch mit optischen Instrumenten direkt in Laserstrahlen.
Avvertenza Le fibre ottiche ed i relativi connettori possono emettere radiazioni laser. I fasci di luce non devono
mai essere osservati direttamente o attraverso strumenti ottici.

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.
