DIRECT ATTACH COPPER CABLES
DESCRIPTION
Tyco Electronic’s QSFP direct attach copper
cable assembly is a low cost alternative for
short reach 4X applications. The design allows
for a serial data transmission up to the QDR
rate of 10Gbps/lane, for an aggregate 40Gbps.
QSFP cable assemblies are hot swappable and
the programmed EEPROM signature enables
the host to differentiate between a copper cable
assembly and a fiber optic module. The
mechanical design of the braid crimp ensures
that EMI radiation is suppressed. Additionally,
the copper cable acts as a natural heat sink.
Low power consumption assists in making the
passive copper cable assembly an economic
solution for within rack, or rack-to-rack applica-
tions. Standard QSFP assemblies are offered
in 26AWG and 28AWG, however, other wire
gauges can be engineered.
• 360 degree cable braid crimp
suppresses EMI
KEY FEATURES
• Assemblies available at DDR
(5Gbps/lane) and QDR
(10Gbps/lane) data rates
• Specialty and cross-over cables
are available
• Optimum cable performance is
obtained when cable equaliza-
tion is customized to system
architecture
• Compatible with industry standard
QSFP cages
• EEPROM signature which can be
customized
• Uses Madison Cable’s high
speed TurboTwin parallel pair
copper cable
• Pull tab unlatching allows com-
pact belly-to-belly application
