Applications
In InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP224 DR4 FL Optical Transceiver delivers 850Gbps (4x 212.5Gbps) transmission over SMF with a reach of 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.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox InfiniBand part MMS4A20-XM800 and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers OSFP MSA, CMIS Rev 5.2, IEEE 802.3dj, OIF 224G-VSR.
Ordering Information
Order this product as OSFP224-DR4-800G-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.
Package
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.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
Quality and Testing
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.
