The NVIDIA InfiniBand Compatible 800G OSFP Passive DAC provides an 800Gbps copper connection between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports with a cable length of 1.5m (5ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for InfiniBand NDR fabrics, GPU clusters and AI training networks.

Product Highlights

• Operating temperature: 0 to 70°C (32 to 158°F)

In InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP Passive DAC provides a factory terminated 800Gbps link between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports. This unit is available in 5 standard lengths from 0.5m (2ft) to 3m (10ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. 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 MCP4Y10-N01A. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox InfiniBand part MCP4Y10-N01A and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers OSFP MSA, IEEE 802.3ck, CMIS v4.0.

The standard part number of this assembly is OSFP-800G-PC. We supply this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 3m (10ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.

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.

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
