Pause Control
The Pause feature can improve network performance by allowing one end of
the link to signal the other to discontinue frame transmission for a set period
of time to relieve buffer congestion.
NOTE: If the Pause feature is present on ALL network devices attached to the
media converter(s), enable the Pause feature on the media converter(s).
Otherwise, disable the Pause feature
Link Pass-Through
The Link Pass-Through feature allows the media converter to monitor both the
fiber and copper RX (receive) ports for loss of signal. In the event of a loss of
an RX signal (1), the media converter will automatically disable the TX
(transmit) signal (2), thus, “passing through” the link loss (3). The far-end
device is automatically notified of the link loss (4), which prevents the loss of
valuable data unknowingly transmitted over an invalid link.
Far-End Fault
When a fault occurs on an incoming fiber link (1), the media converter
transmits a Far-End Fault signal on the outgoing fiber link (2). In addition the
Far-End Fault signal also activates the Link Pass-Through, which, in turn,
disables the link on the copper portion of the network (3) and (4).
