ealth (CDRH) regulation. It cannot, under normal operating conditions (i.e.,
intended use), emit a hazardous level of optical radiation. No warning label or control measures are
required by the FDA/CDRH. The IEC (International Electrotechnical Commission) standard (Publication
60825-1) requires a warning label and specifies that classification be made under fault conditions.
Therefore, systems that are Class 1 under FDA/CDRH rules may not necessarily be Class 1 under the
IEC.
The Laser wavelengths being used on V1679 boards may range from 1310nm to 1610nm. The average
optical output power does not exceed 0 dBm (1mW) under normal operating conditions. Unused optical
outputs are automatically covered with a shutter and prevent direct exposure to the laser beam.
Even though the power of these lasers is low, the beam should be treated with caution and common
sense because it is intense and concentrated. Laser radiation can cause irreversible and permanent
damage of eyesight. Please read the following guidelines carefully:
1.
Make sure that a fibre is connected to the board’s fibre outputs before power is
applied. If a fibre cable (e.g. patchcord) is already connected to an output, make sure
that the cable’s other end is connected, too, before powering up the board.
2.
Do not
look in the end of a fibre to see if light is coming out. The laser wavelengths
being used (most commonly 1310nm and 1550nm) are totally invisible to the human
eye and will cause permanent damage. Always use optical instrumentation, such as an
optical power meter, to verify light output.
