GbX* Cable Assembly
74552
4-Pair Configuration
GbX, the next-generation high-speed backplane interconnect cabling system, delivers over 6 Gbps
and signal density of 55 differential pairs per linear inch
The GbX high-performance backplane cable assemblies
and connectors provide the speed and density required
by leading-edge backplane designs. With a native
differential signaling speed of 6.0 Gbps, the system
is well suited for existing and future generations of
XAUI (10 Gigabit Attachment Unit Interface) and
InfiniBand
†
- based systems.
GbX cable assemblies offer improved capabilities to
current backplane cable products, with impedance
matching, low pair-to-pair crosstalk, within-pair and
pair-to-pair skew control and a variety of raw-cable
designs to meet customer-specific loss budgets. Cables
are available in a 4-pair (column) configuration.
GbX High Performance Cable Assemblies complement
Molex’s existing line of GbX products. For more

Features and Benefits
Design
■
4-pair configuration provides 55 real-differential
pairs per linear inch (2, 3 and 5 pair configurations
are possible extensions)
‡
allowing high density
with more differential pairs than similar backplane
products
■
Bifurcated contact beams assure greater reliability
with two points of contact to header pins
■
Ground shield for individual pairs reduces crosstalk
at the mating interface for improved system
performance

Process
■
Opposed gap-resistance welding re-flows cable
conductor into the signal contact, providing a clean
electrical path
■
Zinc or Aluminum die-cast backshells provide
shielding protection for custom Input/Output
backplane designs
■
Integrated stiffeners and latches provide mechanical
robustness and solid mating to vertical or right-
angle mating (RAM) headers
■
Low-pressure, strain-relief insert molding provides
strain relief for the termination area and allows
tighter cable shield to conductor tolerances for
better impedance control
