Far

End
Fault
Far
‐
End
Fault
is
a
valuable
feature
used
in
a
media
converter
when
it
loses
Receive
Fiber
link,
but
still
has
a
valid
Fiber
Transmit
link.
When
a
fault
occurs
on
an
incoming
fiber
link
(1),
the
media
converter
transmits
a
Far
‐
End
Fault
signal
on
the
outgoing
fiber
link
(2).
In
addition,
the
Far
‐
End
Fault
signal
also
activates
the
Link
Pass
‐
Through,
which
in
turn
disables
the
link
on
the
copper
portion
of
the
network
(3)
and
(4).
