400G QSFP-DD LR4 Transceiver Module

400GBASE-LR4 • 10km-40km SMF • Duplex LC • QSFP-DD • CWDM4 • Low Power < 11W

The 400G QSFP-DD LR4 Transceiver Module is designed for high-speed 400G optical communication over single mode fiber. It supports transmission up to 10km using G.652 SMF with KP-FEC, making it ideal for data center interconnect, cloud networks, telecom backbone, and high-capacity enterprise optical links.

This module converts 8 channels of 50Gb/s PAM4 electrical signals into 4 channels of CWDM optical signals, delivering a total 400Gb/s optical output through a compact QSFP-DD form factor with duplex LC connector.
