NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top

For short reach 400Gbps links in InfiniBand HDR fabrics, HPC clusters and AI computing networks, the NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top offers a factory terminated passive twinax assembly with OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) connectors and a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets OSFP MSA, CMIS Rev4.0, IEEE 802.3cd.

Product Highlights

• OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top)
• Data rate: 400Gbps
• Cable type: Passive Twinax
• Length: 0.5m (2ft) to 2m (7ft), 4 standard options

The NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top is a 400Gbps direct attach copper cable for OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) connections in InfiniBand HDR fabrics, HPC clusters and AI computing networks. This unit is stocked in 4 standard lengths from 0.5m (2ft) to 2m (7ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

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.

Order reference: part number OSFPFL-400G-PC. Standard supply covers 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Custom length production is available for project requirements. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

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.

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.

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.
