ABSTRACT:
Access to the XAUI lanes of a 10 Gigabit Ethernet device is provided when needed for testing of the XAUI electrical interface. Access is provided by extending the XAUI interface contained in a XENPAK interface connector. An embodiment of the present invention uses an extension of the XENPAK connector to generate and receive XAUI signals thus making it possible for any device with a XENPAK connector to become a XUAI tester with minimal components between the test equipment and the device under test. The reduction of components (only an AC-Coupling capacitor resides between the XENPAK connector and the SMA connector) results in significant reduction in insertion loss and signal degradation. Also, the availability of any device with a XENPAK interface as a XAUI tester eliminates any requirement for specialized test equipments. The XAUI Extender card fits in the slot in the test equipment that would normally house the XENPAK module. Thus, no special connector is required to configure a device as a test equipment of the present invention.
