Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type
of cables used. See page 1
(front cover)
for available CFETF10xx-205 models.
The 512-Bit Rule does not apply in a full-duplex network.
Pause Control Frame
The pause control 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 control feature is present on ALL network devices attached
to the media converter(s), enable the pause control feature on the media
converter(s). Otherwise, disable this feature.
Link Pass-Through
When the Link Pass-Through feature is activated, it 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 notified automatically of the link loss (4),
which prevents the loss of valuable data transmitted unknowingly over an
invalid.
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).
