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: available from 0.5m (2ft) to 2m (7ft) in 4 standard options

Designed for InfiniBand HDR fabrics, HPC clusters and AI computing networks, the NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top carries 400Gbps between OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) interfaces. This unit is supplied 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.

Standards compliance covers OSFP MSA, CMIS Rev4.0, IEEE 802.3cd. The unit works in any equipment with a standard OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top) interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

This model carries part number OSFPFL-400G-PC. You can order this assembly in 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Non-standard lengths can be produced on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

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.

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.

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.
