GbX® Module-to-Backplane  
Connector System  
The GbX Backplane Interconnect System Delivers Speeds Beyond 6.0Gbps and  
High Density With Up To 69 Mated Differential Channels Per Inch  
The GbX connector system provides the speed, density, and low applied cost required by leading-edge  
backplane applications. It is especially suited for designs that require future speed upgrades by  
daughtercard replacement into an existing backplane. With a native differential signaling speed of  
6.0Gbps, the system is well suited for existing and future generations of XAUI (10 Gigabit Attachment Unit  
Interface) and InfiniBand* based systems, in addition to those based on ATCA** (Advanced Telecom  
Computing Architecture) and OIF (Optical Internetworking Forum) chip protocols.  
In 4- and 5-Pair Columns

Assemblies  
Internetworking and telecommunication equipment engineers will benefit by the GbX connector’s ability to  
provide not only a high-density, low applied-cost solution in the near term, but also by its electrical  
performance in upgradeable systems. Speeds of 10.0Gbps and beyond have been demonstrated with  
appropriate SERDES (Serializer / Deserializer) devices and board-material selection. This allows system  
architects freedom-of-design for faster future systems without the worry of backwards compatibility, along  
with the economy of a common backplane for two generations of equipment.

Power  
In addition, the GbX L-Series system provides a complimentary high-density open pin field for cost-  
effective design of slower speed circuits along the same stiffener as the standard, high-speed GbX wafers.  
Features and Benefits  
Up to 69 real differential pairs per linear inch  
(27 real differential pairs per 10mm) provide  
higher density than VHDM-HSD®  
Bifurcated contact beams in daughtercard  
receptacle allow greater reliability with two  
points of contact to header pin  
Optimized differential pair contacts allow  
easier board trace routing  
Data rate options up to 10.0Gbps to support  
future daughtercard speed upgrades  
Modular daughtercard components with GbX  
L-Series available as custom, cost-effective  
receptacle assemblies
