NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top
The NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top provides a 400Gbps copper connection between OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) ports with a cable length of 0.5m (2ft). 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 HDR fabrics, HPC clusters and AI computing networks.

Applications
In InfiniBand HDR fabrics, HPC clusters and AI computing networks, the NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top provides a factory terminated 400Gbps link between OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) ports. This unit is made in 4 standard lengths from 0.5m (2ft) to 2m (7ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs 4x 100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: OSFP MSA, CMIS Rev4.0, IEEE 802.3cd. 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
The part number for this assembly is OSFPFL-400G-PC. We offer this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Other lengths can be custom manufactured on request. Wire gauge: 30AWG.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
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.
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.
