Link Fault Pass Through Function
When this function is enabled, a link fault detected on the TP copper port will force a link down on the FX
fiber port and vice versa. Similarly, a link fault detected on the FX fiber port will also force a link down on the
TP copper port.
The following figure illustrates a link fault on the fiber segment between the local and remote media converter
devices is detected and both devices will force a link down on both copper segments.
The following figure illustrates another example. A link fault happened on the copper cable is detected by the
remote end. The fault is forwarded to the fiber segment and also forwarded to the copper cable at the local end
by remote device and local device respectively.
Smart-Forward Function
With this function, the media converter can change to direct conversion automatically when it detects same
speed on both copper port and fiber port. Direct conversion method converts the signal between the copper port
and the fiber port without storing the received packet on one port then forwarding to another port. The media
converter operates with the minimum latency and has no size limit to the forwarded packets. In the case of
100Mbps to 10Mbps conversion, the media converter adapts itself to store-and-forward method for such
unbalancing conversion automatically.
Note:
1. In direct conversion, be sure both devices connected to the TP port and FX port have same duplex mode for
proper transmission.
2. In direct conversion, 802.3x function is disabled and the media converter will not generate pause frame, but
just forwards the received pause frame directly from one port to another port.
