Enabled: If the media converter detects a loss of signal on the fiber receiver, it will immediately disable its fiber transmitter signal on the same port. This, in effect, notifies the fiber link partner that an error condition exists on the fiber connection.

If the remote media converter is set up for Fiber Fault Alert (FFA) and the local media converter is set up with Link Pass-Through, a loss of fiber link will be passed through to the local copper connection thus notifying the connected device.

If the media converter has been set to Smart Link Pass-Through mode, the effect will be the same as FFA, since the link loss on the fiber receiver will result in bringing down the copper link, which will in turn cause the transmit fiber link to be brought down.

Note: This feature only takes effect if Fiber Negotiation has been turned off.

Disabled: The media converter will not monitor for or generate Fiber Fault Alert.
