loss of copper link at the near end device. This would, in effect,
resemble a direct copper connection.
Standard Mode: In this mode, the links on the fiber and copper
sides can be brought up and down independently of each other. A
loss of link on either the fiber or copper port can occur without
affecting the other connection.

Enabled: If the Media Converter Module detects a loss of 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)
and the local Media Converter is set up with 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 Module will not monitor for or
generate Fiber Fault Alert.
