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.

Applications
The NVIDIA InfiniBand Compatible 800G OSFP Passive DAC connects OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) ports at 800Gbps in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is produced 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.
Standards and Compatibility
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.
Ordering Information
The factory part number is OSFP-800G-PC. This cable is available in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 3m (10ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 26AWG.
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.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
