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.
RADIUS LIMITER ARE LABELED 1 THROUGH 5,
PORT DESIGNATIONS ARE LABELED A THROUGH H.
