CETTF10xx-200

Operation -- Continued

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.

Cable Specifications
