obtained when cable equaliza-

tion is customized to system

architecture

• Uses Madison Cable’s high

speed TurboTwin parallel pair

copper cable

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.
