Warning!
Possible laser/LED radiation in the non-visible spectrum!
Never look into open ber ends if the level of risk from laser/LED radiation is not known.
Important
The assignment of the risk level must be specied denitively by the site technician/operator responsible for
the communications facility and must be indicated accordingly (e.g. by attaching standard-compliant warning
signs as per the current edition of DIN EN/IEC 60825-1, and in accordance with the current edition of BGV B2
“Laser radiation”). If there is any change in the technical data relating to the risk level, the warnings must be
adapted accordingly and occupational safety precautions must be taken if required, see also e.g. the current
edition of DIN EN/IEC 60825-2.
