Applications
The 800G OSFP 2x FR4 Optical Transceiver is used in InfiniBand NDR fabrics, GPU clusters and AI training networks, where it provides an 850Gbps (8x 106.25Gbps) link over SMF up to 2km. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. It is interoperable with NVIDIA/Mellanox InfiniBand platforms and replaces the NVIDIA/Mellanox InfiniBand part MMS4X50-NM directly. The link runs 8x100G-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 MMS4X50-NM and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers OSFP MSA HW Rev 4.1, CMIS Rev 5.0, IEEE 802.3cu-2021, IEEE P802.3ck D2.2.
Ordering Information
Order this product as OSFP-2FR4-800G. 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 Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
Packing Details
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.
Factory Custom Capability
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
