Potential sources of danger
Beware of the following potential sources of danger which will remain despite all
safety measures taken:
•
Laser radiation can cause damage to the skin and eyes.
•
Laser radiation from optical transmission systems is in a wavelength range that is
invisible to the human eye.
Laser classes
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
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.

“Laser product classification” (p. 1-16)
Laser safety instructions
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 look 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 or 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.
