FO 400G QSFP-DD ER4 is a 400Gb/s QSFP-DD optical transceiver module designed for long-haul transmission. It converts eight 50Gb/s PAM4 electrical inputs into four LAN-WDM optical channels, multiplexed into a single 400Gb/s optical signal. On the receive side, the 400Gb/s signal is demultiplexed and converted back into eight 50Gb/s PAM4 electrical outputs. Operating at LAN-WDM wavelengths of 1295.56, 1300.05, 1304.58, and 1309.14 nm, the module uses single-mode fiber (SMF) to minimize dispersion, making it ideal for data center interconnection and other high-performance, long-distance networking applications. The 400G QSFP-DD ER4 optical transceiver delivers ultra-high-density 400 Gigabit Ethernet connectivity for data centers and high-performance computing (HPC) networks. It supports long-reach interconnects between 400G QSFP-DD switches, enabling flexible, reliable, and efficient device-to-device connectivity across a wide range of deployment scenarios.

Fyber Optix is a British-engineered brand of OEM-compatible optical networking products, including SFP, SFP+, QSFP+, QSFP28 and QSFP-DD transceivers, DWDM/CWDM systems, media converters, and DAC/AOC cables. Every module is 100% pre-shipment tested and coded for seamless compatibility with major platforms such as Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet — backed by a lifetime warranty, fast global delivery, and dedicated technical support for data centers, telecom operators, enterprise networks and system integrators worldwide.
