The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 4x 200G OSFP 2x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable provides an 800Gbps copper connection between OSFP (IHS/Finned Top) to 4x OSFP (IHS/Finned Top) ports with a cable length of 0.5m (5ft). 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.

The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 4x 200G OSFP 2x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable is an 800Gbps direct attach copper cable for OSFP (IHS/Finned Top) to 4x OSFP (IHS/Finned Top) connections in InfiniBand NDR fabrics, GPU clusters and AI training networks. This unit is offered in 4 standard lengths from 0.5m (2ft) to 2m (7ft). The breakout design lets one high speed port feed 4x OSFP (IHS/Finned Top), which raises port utilization and simplifies cabling in dense rows. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 8x100G-PAM4 to Quad 2x100G-PAM4 modulation, which keeps it aligned with current 800G switch silicon.

This product is designed and tested to comply with OSFP MSA, CMIS Rev4.0, IEEE 802.3ck. It plugs into any standards-based OSFP (IHS/Finned Top) to 4x OSFP (IHS/Finned Top) port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

Order this assembly under part number OSFP-800G-4OPC. Available lengths are 0.5m (2ft), 1m (3ft), 1.5m (5ft) and 2m (7ft). If you need a length outside this list, our factory can build it to order. 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.

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.

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.
