Coding confirmed against your switch model

The 400GBASE-DR4 QSFP-DD transceiver delivers 400 Gbps over single-mode fiber (SMF) through an MPO interface, up to 500 m. It is hot-pluggable, QSFP-DD MSA-compliant, and supports DDM digital diagnostics.

Typical deployments

400G QSFP-DD is the current spine and AI-fabric building block, packing eight lanes into a double-density QSFP slot. SR8 and DR4 use MPO multimode to 500 m; FR4 and LR4 use LC single-mode up to 10 km.

Before you order

MPO links are polarity-sensitive: confirm the MPO polarity and fiber count match your patch panel before installation, and clean both end faces. Share your switch model and port type so we confirm the coding for your equipment; every module ships with a 3-year warranty and free technical support.
