6 Tbps, high-density access, aggregation or core switch designed for enterprise data centers, cloud service providers, and telcos. Supports a maximum of 64 400G QSFP-DD® ports Supports centralized configuration, compliance, policy, monitoring, and. High-performance 25. What Makes a Switch QSFP-DD Compatible? A switch is. His switch ports contained twelve 800G QSFP-DD modules, which remained inactive. The maintenance window reached its midpoint. His rollback plan assumed the old modules would still work—they did—but that didn't solve his problem. 8mm pitch and a dual-mating interface. This. Quad Small Form-factor Pluggable Double Density (QSFP-DD) solution that fits into high-density switch and router client ports for optical interconnect links Powered by Greylock and Delphi DSP ASICs, and silicon photonic integrated circuits (PICs) for an optimized co-packaged design with 3D. QSFP-DD (quad small form-factor pluggable double density) doubles the capacity of QSFP interconnects with an eight-lane electrical interface capable of 28 Gbps NRZ, 56 Gbps PAM4, and 112 Gbps PAM4 to achieve up to 800 Gbps per port.
