400G QSFP-DD

400G QSFP-DD is an optical module for high-speed network connectivity that supports data rates up to 400Gbps per port. QSFP-DD stands for Quad Small Form-factor Pluggable Double Density, and is a double-density version of QSFP.

The QSFP-DD provides higher port density than the traditional QSFP28 because it achieves double the number of pins in the same size. As a result, it can provide more ports in the same space, thereby increasing network capacity and efficiency in the data center.

400G QSFP-DD modules are typically used to connect high-speed network devices such as data center switches, routers, and servers for high-capacity data transmission. They typically use multimode fiber (MMF) or single-mode fiber (SMF) transmission media and support standard fiber connection interfaces such as LC or MPO.
