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 provides an 800Gbps copper connection between 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top) ports with a cable length of 2m (7ft). 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.

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 supplied in 6 standard lengths from 0.5m (2ft) to 3m (10ft). By fanning one port out to 2x 400G OSFP (IHS/Finned Top), it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs 8x 100G PAM4 to Dual 4x 100G PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Compliance: OSFP MSA, IEEE 802.3ck, CMIS v4.0. 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.

This model carries part number OSFP-800G-2OPC. You can order this assembly in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Non-standard lengths can be produced on request. Wire gauge: 28AWG. Volume pricing is available for project quantities.

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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

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.
