Infrared radiation is invisible
and can seriously damage the
retina of the eye. Do not look
into the ends of any optical fiber.
Do not look directly into the
optical adapters of the adapter
packs. Exposure to invisible
laser radiation may result.
A protective cap or hood
MUST be immediately placed
over any radiating adapter
or optical fiber connector
to avoid the potential of
dangerous amounts of radiation
exposure. This practice also
prevents dirt particles from
entering the connector
and adapter.
Danger:
