QSFP-DD Interconnect System & Cable Assemblies

Molex QSFP-DD (Double Density) Interconnect System and Cable Assemblies feature an eight-lane electrical interface that transmits up to 28Gbps NRZ or 56Gbps PAM-4, up to 200Gbps or 400Gbps aggregate. QSFP-DD offers the same footprint as QSFP interconnects, making them backward compatible. The double density feature is an extended paddle card with two rows of high-speed context. Molex QSFP-DD meets IEEE 802.3bj, InfiniBand EDR, and SAS 3.0 specifications, allowing these connectors and cable assemblies to function across a variety of next-generation technologies and applications. The series includes sheet metal (stainless steel) EMI cages with increased robustness and cable assemblies in lengths ranging from 500mm to 2.5m.
