FO Arista QDD-400G-VR4 compatible 400G QSFP-DD VR4 optical transceiver is a multimode, 4-channel (VR4) optical module designed for 400 Gigabit Ethernet (GbE) links over up to 50 m of OM4 multimode fiber. The QDD-400G-VR4 converts eight lanes of 50 Gb/s PAM4 electrical signals into four lanes of 100 Gb/s PAM4 optical signals at a nominal wavelength of 850 nm, enabling a total aggregate data rate of 400 Gb/s. The 400G QSFP-DD VR4 optical transceiver delivers ultra-high-density 400 Gigabit Ethernet connectivity for data centers and high-performance computing (HPC) networks. It supports short-reach interconnects between switches and network interface cards (NICs) equipped with QSFP112 or OSFP ports, enabling flexible 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.
