NVIDIA InfiniBand Compatible 800G OSFP Passive DAC

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.

The NVIDIA InfiniBand Compatible 800G OSFP Passive DAC is an 800Gbps direct attach copper cable for OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) connections in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is provided in 5 standard lengths from 0.5m (2ft) to 3m (10ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MCP4Y10-N01A. The link runs 8x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Compliance: OSFP MSA, IEEE 802.3ck, CMIS v4.0. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MCP4Y10-N01A directly, with identical fit and function. 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.

This assembly is listed under part number OSFP-800G-PC. The cable is supplied in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft) and 3m (10ft). Custom lengths beyond the standard range are available on request. Wire gauge: 26AWG. Volume pricing is available for project quantities.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

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.

We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
