QSFP-DD interconnect is in major development mode
QSFP-DD (double density) interconnect is an 8 lane x 25 Gbps, NRZ modulation = 200 Gbps and also, 8 lane x 50 Gbps PAM4 modulation = 400 Gbps system. It is based on the widely adapted QSFP interconnection system that is especially used in datacenters and HPC centers. It has evolved from a birds-of-a-feather coalition into the new QSFP-DD MSA consortium that has formed and announced the intent to produce and release a fairly detailed specification.
