NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top

The NVIDIA InfiniBand Compatible 400G OSFP Passive DAC Flat Top is a passive twinax direct attach copper cable with OSFP (RHS/Flat Top) to OSFP (RHS/Flat Top), supporting 400Gbps links over a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for InfiniBand HDR fabrics, HPC clusters and AI computing networks, and complies with 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: 4 standard lengths between 0.5m (2ft) to 2m (7ft)

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 provided 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. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

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 assembly is listed under part number OSFPFL-400G-PC. The cable is supplied in 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG.

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.

As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.

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.
