QSFP-DD, or QSFP56-DD, stands for Quad Small Form Factor Pluggable Double Density. Based on the design of QSFP, the form factor of QSFP-DD is identical to the previous QSFP+ and QSFP28. Yet it doubles the number of electrical interface lanes to 8 against 4 and provides the highest bandwidth in the QSFP cage system module.
