Network architects choose the 400G QSFP112 SR4 Optical Transceiver for InfiniBand HDR fabrics, HPC clusters and AI computing networks: it runs 425Gbps (4x106.25Gb/s) over MMF and reaches 30m@OM3/50m@OM4. The MPO-12/APC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MMA1Z00-NS400. The link runs 4x100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

This product is designed and tested to comply with QSFP112 MSA, CMIS Rev5.0, IEEEdf-2024. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MMA1Z00-NS400.

Order this product as QSFP112-SR4-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.
