There are reverse gender Quadrax contacts to provide a more robust assembly for harsh environment applications. This alternative configuration places the stronger and larger diameter inner socket contacts within the more exposed Quadrax pin contact insulator. The more fragile inner pin contacts are then placed within the Quadrax socket contact insulator minimizing the potential of alignment damage due to mishandling on both sides.

Testing Capabilities
Smiths Connectors Quadrax and Twinax interconnects are characterized for testing eye pattern, jitter, skew, and insertion loss on differential pair 100 ohm high speed Gigabit Ethernet applications with a wide variety of testing protocols. We utilize the Agilent E5071C 4 port network analyzer to measure the differential pair TDR impedance between Twinax connectors, cable assemblies, and quad cable Ethernet and Fibre Channel interconnect systems ensuring the most accurate acquired signal for high speed communications testing. The E5071C 4 port network analyzer is capable of highly accurate 100 Ohm differential measurements up to 20 GHz and can measure Eye Diagrams up to 16 Gbps.
