GUIDELINES
■
The suggested cable type is 62.5/125 or 50/125 multimode fiber
optic SC.
■
Maximum cable length of 62.5/125 multimode fiber is 220
meters, maximum cable length of 50/125 multimode fiber is 550
meters.
■
The maximum number of switches between two end nodes sug-
gested by the IEEE is seven.
■
Make sure the TX (transmit) end of the multimode SC cable is
connected to the RX (receive) por t on the Gigabit device and the
RX end of the multimode SC cable is connected to the TX por t on
the Gigabit device. Do not detach the cable ends from any
labelled clips, and do not attempt to dismantle the cable in order
to ‘cross over’ the cable. Fiber cables are already crossed over.
