Applications
The NVIDIA Ethernet Compatible 800G OSFP 2x LR4 A2 Optical Transceiver is used in 800G Ethernet data centers, HPC and machine learning clusters, where it provides an 850Gbps (8x 106.25Gbps) link over SMF up to 10km. The Dual Duplex LC/UPC interface and 1271nm, 1291nm, 1311nm and 1331nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards and Compatibility
Compliance: OSFP MSA HW Rev 4.1, CMIS Rev 5.0, MSA- 2x400G-LR4-10, IEEE P802.3ck D3.0. 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.
Ordering Information
Order this product as OSFP800-2LR4-A2. 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.
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.
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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
