Laser Safety - Fiber Output SFP and QSFP Modules Warning
The average optical output power does not exceed 0 dBm (1mW) under normal operating
conditions. Unused optical outputs should be covered to prevent direct exposure to the
laser beam.
Even though the power of these lasers is low, the beam should be treated with caution
and common sense because it is intense and concentrated. Laser radiation can cause
irreversible and permanent damage of eyesight. Please read the following guidelines
carefully:
•
•
Mains Supply Voltage
Before connecting the equipment, observe the safety warnings section and ensure that the
local mains supply is within the rating stated on the power supply.

LASER SAFETY
Make sure that a fiber is connected to the board's fiber outputs before power is
applied. If a fiber cable (e.g. patchcord) is already connected to an output, make sure
that the cable's other end is connected, too, before powering up the board.
Do not look in the end of a fiber to see if light is coming out. The laser wavelengths
being used are totally invisible to the human eye and can cause permanent damage.
Always use optical instrumentation, such as an optical power meter, to verify light
output.
