Network architects choose the NVIDIA InfiniBand Compatible 800G OSFP224 DR4 FL Optical Transceiver for InfiniBand NDR fabrics, GPU clusters and AI training networks: it runs 850Gbps (4x 212.5Gbps) over SMF and reaches 500m. With its MPO-12/APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with NVIDIA/Mellanox InfiniBand platforms and replaces the NVIDIA/Mellanox InfiniBand part MMS4A20-XM800 directly. The link runs 4x 200G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Compliance: OSFP MSA, CMIS Rev 5.2, IEEE 802.3dj, OIF 224G-VSR. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MMS4A20-XM800 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.

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.

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.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

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.
