Built for InfiniBand HDR fabrics, HPC clusters and AI computing networks, this Single-port OSFP RHS/Flat Top module carries 425Gbps (4x106.25Gbps) over MMF up to 30m@OM3/50m@OM4 or OM5 per link. The MPO-12/APC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with NVIDIA/Mellanox InfiniBand systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of MMA4Z00-NS400.

Compliance: 400G InfiniBand NDR, OSFP MSA Rev 5.0、IEEE 802.3ck、IEEE 802.3-2022. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MMA4Z00-NS400 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

Order this product as OSFP-SR4-400G-FL. 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.

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.

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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
