Laser Safety Information and Guidelines
2:2004+A1:2006+A2:2010. Such a high optical power can be potentially harmful to the
human eye and skin. To comply with Class 1M laser safety requirements, EDFAs and
Raman amplifiers are equipped with different firmware safety mechanisms designed to
detect a fiber break or connector opening, and as a result of this, to activate APR and/or
automatic power shutdown (APS) functions, depending on the amplifier type.
The APR function limits the output signal power by reducing the pump power within a
specified amount of time, as defined by hazard level 1M requirements according to IEC
60825-2. The APS function shuts down the pump laser within less than 1 second to
prevent the amplified signal or Raman pump out from being transmitted into the open or
broken fiber. To ensure that the HD system operates as a hazard level 1M system, some
EDFAs and the Raman amplifiers supports the ADVA Optical Networking ALS scheme.
LASERRADIATIONWARNING
The organization in charge of operation and maintenance carries
the final responsibility for the safety of the entire system. That
includes particularly to ensure that:
l The laser hazard levels are not exceeded in the various areas
for normally foreseeable events;
l In controlled secured and particularly secured areas in view of
reasonably foreseeable malfunctions, laser hazard level 1M has
to be notified;
l Installation and service are only executed by organizations that
are able to fulfill the regulations of standard IEC 60825-2;
l Appropriate measures are taken for the access to particularly
secured and secured areas regarding laser safety; and
l The regulations regarding the operation, installation, and
maintenance of the system, as well as safety instructions, are
always followed.
LASERRADIATIONWARNING
Only configurations approved by ADVA Optical Networking are
guaranteed to comply with laser Class 1M.
LASERRADIATIONWARNING
Risk of laser infrared radiation!
Use of controls, adjustments, or performance of procedures other than
those specified in this document may result in hazardous radiation
exposure.
