Product Features
AutoCross ™
The AutoCross feature detects and configures the twisted-pair copper port on
the CETTF10xx-200 media converter to the correct straight-through (MDI) or
crossover (MDI-X) configuration. This feature allows either MDI or MDI-X
cable to connect the media converter to devices such as hubs, transceivers, or
network interface cards (NICs).
NOTE: When AutoCross is disabled, the 10Base-T (copper) port is in MDI-X
(crossover) mode.
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.
NOTE: An enable/disable switch allows the Link Pass-Through feature to be
disabled. Link Pass-Through may interfere with the Auto-Negotiation feature
of other devices in networks where there are two media converters installed in
series.
