The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G OSFP 4x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable provides an 800Gbps copper connection between 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) ports with a cable length of 2m (7ft). 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 8x 100G PAM4 to 2x 400G OSFP 4x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable is an 800Gbps direct attach copper cable for 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) connections in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is produced in 6 standard lengths from 0.5m (2ft) to 3m (10ft). By fanning one port out to 2x 400G OSFP (IHS/Finned Top), it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.
Standards and Compatibility
This product is designed and tested to comply with OSFP MSA, IEEE 802.3ck, CMIS v4.0. It plugs into any standards-based 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The factory part number is OSFP-800G-2OPC. This cable is available in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 28AWG.
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.
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.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
Quality Assurance
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.
