Link Mode
Link Mode provides a transparency to the state of the copper link allowing for simplified trouble
shooting from the devices connected to the media converter.
Normal (Default — Up)
With Fiber Auto Negotiation enabled when the copper link goes down the 1000Base-X link is
brought down. The 1000Base-X link will advertise Remote Fault (Link Fault).
With Fiber Auto Negotiation disabled the state of the copper link has no effect on the 1000Base-X
link.
Smart Link Pass Through (Down)
With Fiber Auto Negotiation enabled the behavior is as follows. When the copper link goes down the
1000Base-X link is brought down. The 1000Base-X link will advertise Remote Fault (Link Fault).
When Remote Fault (Link Fault) is received on the 1000Base-X interface the copper transmitter will
be turned off. When the copper receiver is off the 1000Base-X transmitter will be turned off. When
the 1000Base-X receiver goes off the copper transmitter will be turned off.
With Fiber Auto-Negotiation disabled the behavior is as follows. When the copper receiver is off the
1000Base-X transmitter will be turned off. When the 1000Base-X receiver goes off the copper

Enabled (Default - Up)
When the 1000Base-X receiver is off the 1000Base-X transmitter is turned off. Periodically the
1000Base-X receiver will be turned on for a short period to allow the condition to clear if the
1000Base-X link partner is using a similar feature.
Disabled (Down)
Loopback
The media converter can perform a loopback on the 1000Base-X fiber interface.

Fiber Negotiation
Up: The Media Converter will negotiate Ethernet parameters on the fiber connection. This will
ensure that the most optimal connection parameters will be in effect. If connecting to another Perle
Media Converter, this parameter should be set to Auto. The Media Converter Module will advertise
1000Mbps, Full and Half Duplex, no Pause.
Down: The Media Converter Module’s fiber will be fixed to 1000Mbps, Full Duplex.
