WARNING
Hazardous light emissions may exist in fiber optic systems.
Severe eye damage may result if precautions are not taken.
Never look into a transmitting fiber optic device, transceiver,
repeater, or cable.
Maximum segment length is 1000 meters (3279 ft.) for FOIRL
and 2000 meters (6558 ft.) for 10BASE-FL. In a 10BASE-FL or
FOIRL segment, the cables connect the transmit receptacle at
one end of the segment to the receive receptacle at the other end
and vice versa. Be sure to align the key on the cable connector
with the keyway on the adapter card receptacle when attaching
the cable. Forcing cable insertion can cause receptacle or
connector damage.
