Gigabit Media Converter – Installation Guide
5
If the installation has a media converter on both ends of the fiber
link and both are setup for Smart Link Pass-Through, then a loss
of copper link on the far end device will propagate through both
media converters and will result in a loss of link at the near end
device. This would, therefore, resemble a direct copper
connection.

Enabled: If the media converter detects a loss of fiber signal on
the fiber receiver, it will immediately disable its fiber transmitter
signal. 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)
Enabled and the local media converter is set up with Smart Link
Pass-Through, a loss of fiber link on either the transmit or receive
line 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 fiber fault.
