passed through to the local copper connection thus notifying the
connected device.
If the media converter has been set to Link Pass-Through mode,
the effect will be the same as FEF, 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: To generate or detect the FEF signal switch 3 needs to be
enabled.
Disabled: The media converter will not monitor for or generate
Far End Fault.
The following diagram is an illustration of the operation of this
feature.
(A) – Remote Media Converter setup for Far End Fault Enabled,
Auto Negotiation – OFF and Link Mode – Standard.
(B) – Local Media Converter setup for Far End Fault enabled, Link
Pass-Through On and Auto Negotiation - OFF
1) (A) Loses fiber connection on its receiver.
2) (A) Sends FEF.
3) (B) Detects FEF signal and shuts down the fiber link.
4) (B) Drops link on copper connection because Link Pass-
Through is configured.
5) (A) Link on copper connection is not affected because Link
Mode is set to Standard.
