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 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: If it is required to either generate or detect the FEF signal, then the FEF switch needs to be set.

Disabled: The Media Converter Module 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.
