Data rates up to 10 Gbps may now be achieved with
the GbX 2 and 3-pair column daughtercard and
backplane system. The 2 and 3-pair column system
completes the GbX product offering, making it a
complete solution for high-end telecommunication and
datacommunication applications.
solution in the near term, but also by its electrical
performance in upgradeable systems. Speeds of 10
Gbps 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
backward compatibility, along with the economy of a
common backplane for two generations of equipment.

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.
In addition, the GbX Lite Series system provides a
complimentary high-density open pin field for cost-
effective design of slower-speed circuits along the same

GbX 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.
