Built for InfiniBand NDR fabrics, GPU clusters and AI training networks, this Single-port OSFP RHS/Flat Top module carries 850Gbps (4x 212.5Gbps) over SMF up to 500m per link. With its MPO-12/APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. 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 MMS4A20-XM800. The link runs 4x 200G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

This product is designed and tested to comply with OSFP MSA, CMIS Rev 5.2, IEEE 802.3dj, OIF 224G-VSR. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MMS4A20-XM800.

Our part number for this module is OSFP224-DR4-800G-FL. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.

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.
