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

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
