Fiber Optics Powerwave
1 - 2 Rev. P1A9-Draft 2004-11 VM100 56/EN – User’s Manual
• The FON unit contains a class IIIb laser transmitter that emits 2 – 5mW invisible laser
radiation during operation. Avoid direct exposure from unconnected laser transmitter
or fiber cord as follows:
– Do not power up the FON unit if a fiber cable is not attached to the fiber output
UL port, neither if a fiber cable is attached to the port but unattached in the other
end.
– Never look in the end of a fiber cable. The 1310nm and 1550nm laser light is
not visible, so no signal identification can be made anyway. Use always an
instrument, such as a power meter to detect signaling.
– Never use any kind of magnifying devices that can focus the laser light to an
unprotected eye.
