SAFETY INFORMATION

LASER RADIATION AND CONNECTORS

When the connector is in place, all laser radiation remains within the fiber. The maximum

amount of radiant power exiting the fiber (

under normal conditions

) is -12.6 dBm or 55 x 10 -6

watts. Removing the optical connector from the transceiver allows laser radiation to emit

directly from the optical port. The maximum radiance from the optical port (under worst case

conditions) is 0.8 W cm -2 or 8 x 10 3 W m 2 sr-1.

Do not use optical instruments toviewthe laser output. Theuse of optical instruments

to view laser outputincreaseseye hazard. When viewing the outputoptical port, power

must be removed from the network adapter.
