Laser Safety Guidelines
WARNING: Use of controls, adjustments, and procedures other than
those specified in this document may result in hazardous laser
radiation exposure.
Optical fiber telecommunication systems, their associated test sets, and similar
operating systems use semiconductor laser transmitters that emit infrared (IR) light
at wavelengths between approximately 800 nanometers and 1600 nanometers.
The emitted light is above the red end of the visible spectrum, which is normally
not visible to the human eye. Although radiant energy at near-IR wavelengths is
officially designated invisible, some people can see the shorter wavelength energy
even at power levels several orders of magnitude below any that have been shown
to cause injury to the eye.
