Perle 10/100/1000 Media Converter Module – Installation Guide
9
Enabled: If the Media Converter Module detects a loss
of signal on the fiber receiver, it will immediately
disable its fiber transmitter signal. 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 Fiber Fault
Alert (FFA) and the local Media Converter is set up with
Link Pass-Through, a loss of 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 Smart Link
Pass-Through mode, the effect will be the same as
FFA, 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: This feature only takes effect if Fiber Negotiation
has been turned off.
Disabled: The Media Converter Module will not
monitor for or generate Fiber Fault Alert.
The following diagram is an illustration of the operation
of this feature.
(A) – Remote Media Converter setup for Fiber Fault
Alert Enabled, Fiber Negotiation – OFF and Link Mode
