NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G OSFP 4x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable

The NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G OSFP 4x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable is a passive breakout dac direct attach copper cable with 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top), supporting 800Gbps links over a length of 2m (7ft). 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 NDR fabrics, GPU clusters and AI training networks, and complies with OSFP MSA, IEEE 802.3ck, CMIS v4.0.

In InfiniBand NDR fabrics, GPU clusters and AI training networks, the NVIDIA InfiniBand Compatible 800G OSFP 8x 100G PAM4 to 2x 400G OSFP 4x 100G PAM4 InfiniBand NDR Passive Breakout DAC Cable provides a factory terminated 800Gbps link between 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) ports. This unit is available in 6 standard lengths from 0.5m (2ft) to 3m (10ft). One port becomes 2x 400G OSFP (IHS/Finned Top), a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request.

This product is designed and tested to comply with OSFP MSA, IEEE 802.3ck, CMIS v4.0. It plugs into any standards-based 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

The standard part number of this assembly is OSFP-800G-2OPC. We supply this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.

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.

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.

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.

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.
