Link Pass-Through:In this mode, the link state on one connection is directly reflected through the Media Converter Module to the other connection. If the link is lost on one of the connections, then the other link will be brought down.

With Media Converters on both ends of the fiber link and both setup for Link Pass-Through, a loss of copper link on the far end device will propagate through both Converters and will result in a 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 receive fiber signal, it will transmit a FEF signal to the remote Media Converter. 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 Far End Fault (FEF) and the local Media Converter is set up with Link Pass-Through, a loss of
