The FS OSFP-SR4-400G-FL Compatible LINK-PP module is a single-port flat-top OSFP-RHS 400G SR4 multimode optical transceiver operating with 100G PAM4 modulation. Equipped with an MPO-12/APC four-channel optical interface, it supports 400G transmission up to 50 meters over OM4 fiber.Validated for end-to-end InfiniBand NDR deployments, this module works seamlessly with ConnectX-7 OSFP adapters and 2×400G InfiniBand switches. A standout capability enables flexible 2×200G breakout connectivity when paired with a 1:2 fiber splitter cable. It activates only two optical lanes per split path to cut power draw, delivering cost-efficient multi-rate interconnection.
Boasting robust high-bandwidth performance and ultra-low BER characteristics, the transceiver is purpose-built for HPC, supercomputing and AI clusters, with native interoperability matching H100 and H200 GPU architectures.
