The maximum output power of laser radiation depends on the type of
laser diode used. The international standards IEC 60825 and
DIN/EN 60825 respectively as well as the Food and Drug
Administration's Center for Devices and Radiological Health
(FDA/CDRH) regulations define the maximum output power of laser
radiation for each laser class in accordance with the wavelength.
The classification scheme is based on the ability of the laser emission or
the reflected laser emission to cause injury to the eye or skin during
normal operating conditions.
Please also refer to Laser product classification (1-15).
Observe the following instructions to avoid exposing yourself and others
to risk:
• Read the relevant descriptions in the manuals before taking
equipment into operation or carrying out any installation and
maintenance work on the optical port units, and follow the
instructions. Ignoring the instructions may result in hazardous laser
radiation exposure.
• Do not view directly into the laser beam with optical instruments
such as a fiber microscope, because viewing of laser emission in
excess of Class 1 limits significantly increases the risk of eye
damage.
• Never look into the end of an exposed fiber or an open connector as
long as the optical source is still switched on.
• Ensure that the optical source is switched off before disconnecting
optical fiber connectors.
• In the event of doubt, check that the optical source is switched off
by measuring with an optical power meter.
CAUTION
Use of controls, adjustments and procedures other than those
specified herein may result in hazardous laser radiation exposure.
