400G QSFP-DD is a high-speed optical transceiver package featuring a "Double Density" design. It achieves a total transmission bandwidth of 400 Gbps through 8 electrical channels, typically employing 50G PAM4 modulation per channel.
400G QSFP-DD is primarily used for high-speed interconnections within data centers, such as between switches and servers. While maintaining physical compatibility with mainstream QSFP28 ports and offering higher port density, this package generally has higher power consumption and more demanding thermal requirements compared to the 400G QSFP112 solution you previously inquired about, which utilizes four 112 Gbps channels.
