GbX® Backplane
Connector System
Delivering high density and speeds up to 10 Gbps, the
custom-configurable GbX® Backplane Connector System is
prime for telecom and datacom designs requiring future
speed upgrades
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 native differential signaling speeds up to 10 Gbps,
the GbX Backplane Connector System is well suited for existing and future
generations of 10 Gigabit Attachment Unit Interface (XAUI) and InfiniBand†
based systems, in addition to those based on Advanced Telecom Computing
Architecture (ATCA‡) and Optical Internetworking Forum (OIF) chip protocols.

Networking and telecommunication equipment engineers will benefit by
the GbX connector’s ability to provide not only a high-density, low applied
costsolution in the near term, but also by its electrical performance in
upgradeable systems. Speeds up to 10 Gbps have been demonstrated with
appropriate Serializer / Deserializer (SERDES) devices and board-material
selection. This allows system architects freedom-of-design for faster future
systems without the worry of backward compatibility, along with the economy
of a common backplane for two generations of equipment.

Backplane Power
The GbX Lite Series system provides a complementary high-density, open-pin
field for costeffective design of slower-speed circuits along the same stiffener
as the standard, high-speed GbX wafers.
