3.2 Making FX Port Connection

FX port operates on 100Mbps and full duplex. The following figures illustrate a connection example between
two fiber ports:
Duplex Connection
Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Bi-Di Connection (Bi-Directional)
Far End Fault Function
The FX port is facilitated with this function, which conforms to IEEE 802.3u 100BASE-FX specifications.
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 converter to report a fiber link fault even when a
link failure occurred on transmitting fiber cable.
