2.10 Making Fiber Connections
FX7 port and FX8 port operate on 100Mbps and full duplex.
The following figure illustrates a connection example between two fiber ports:
Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Far End Fault Function
The FX ports are facilitated with this function, which conforms to IEEE 802.3u 100BASE-FX specifi-
cations. When the FX port detects a link failure on its receiving circuitry, it will send out an FEFI (Far
End Fault Indication) signal to the remote connected device to indicate a remote fault is detected. It
also is capable to receive FEFI signal sent from the remote link partner. Upon receiving an FEFI signal,
it indicates a link failure occurred on the transmitting path. This function allows the switch to report a
fiber link fault even when a link failure occurred on transmitting fiber cable.
