GORE™ QSFP Copper Cable Assemblies

QSFP Copper Cable Assemblies

GORE™ QSFP Copper Cable Assemblies provide superior signal fidelity over long distances using the smallest, most flexible cable. These high performance assemblies are engineered to be compliant with all the latest IBTA/IEEE specifications, and to perform beyond the standard InfiniBand QDR data rate (up to 10 Gbps/channel). For the emerging 40 Gbps Ethernet market, 40GBASE-CR4 assemblies are also available.

GORE™ QSFP Copper Cable Assemblies incorporate the latest cable technologies, unique materials, and semi-automatic manufacturing to produce high quality assemblies for interconnects ideally suited for InfiniBand applications. The use of advanced low-loss dielectric materials and GORE™ EYE-OPENER+® Conductor Technology results in exceptional signal fidelity and improved bend radius over longer distances in small cross-sectional areas.
