Frequently Asked Questions

Can QSFP28 100GbE transceivers be used in the QSFP-DD ports?

Yes — QSFP-DD ports are backward compatible with QSFP28 modules, enabling 100GbE connectivity in a 400GbE switch for mixed-speed deployments.

What is QSFP-DD?

QSFP-DD (Quad Small Form-factor Pluggable Double Density) is a high-density transceiver form factor supporting 400GbE via 8x 50Gbps lanes — double the density of standard QSFP28.

The Arista DCS-7050DX4-32S delivers 32-port 400GbE QSFP-DD Layer 3 switching at up to 25.6 Tbps — a next-generation data center spine switch for high-density 400GbE AI/ML, HPC, and cloud fabric deployments with Arista EOS automation.
