The NVIDIA/Mellanox Compatible 400GBASE-FR4 QSFP112 transceiver module supports a max data rate of 425Gbps. It enables the fiber link of 2km over SMF with duplex LC/UPC connectors. QSFPTEK manufactured 400GBASE-FR4 QSFP112 complies with 400G InfiniBand NDR, QSFP112 MSA Rev2.0, 400GBASE-FR4 (IEEE802.3cu), IEEE 802.3ck and CMIS Rev5.0. DDM function is supported on the 400G fiber optic transceiver to achieve real-time operating parameters monitoring. Adopting the Pulse-amplitude Modulation (PAM4) electrical and optical modulation, the FR4 QSFP112 achieves 400 Gigabit Ethernet through 4-channels of 100G-PAM4. The 400G FR4 QSFP112 is widely used for 400 gigabit Ethernet, 800G to 2x 400GBASE-FR4 breakout, data center and InfiniBand NDR applications.
This 400G FR4 QSFP112 supports both InfiniBand NDR (IB) and Ethernet (ETH). While not for use in switches, it is designed for insertion into 400Gb/s ConnectX-7/QSFP112-based PCIe-bus network cards to twin-port 800G transceivers in 2x400G IB/EN switches.
Take a look at our test program to get the reliable and high-performance optical transceivers.

Transceivers type QSFP112 FR4 | 2km | Single Duplex LC/UPC | Flat Top
I bought these for a smaller 400G rollout rather than a full network replacement. They did what we needed without adding extra complexity, and the rollout stayed on schedule.
