QSFP= is a 40 Gbps connection. QSFP28 is a 100 Gbps connection. SFP-DD is the next-generation SFP form factor for DAC and AOC cabling, and optical transceivers. The innovative electrical interface is designed to support two lanes that operate up to 25 Gbps NRZ or 56 Gbps PAM4 per lane modulation, providing aggregate bandwidth of 50 Gbps NRZ or 112 Gbps PAM4 with excellent signal integrity.
