Link Pass
Through
Link Pass Through is a troubleshooting feature that allows the media converter to monitor both
the fiber and copper RX ports for loss of signal. In the event of a loss of RX signal on one
media port, the converter will automatically disable the TX signal of the other media port, thus
"passing through" the link loss. (see diagram below)
* End device automatically notified of link loss
* Prevents loss of valuable data unknowingly transmitted over invalid link
Note: Once the fault condition is resolved, the LNK/ACT LED will blink for 2 ~ 6 seconds
while the connection is recovering from the failure.
