NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable
The NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable provides a 400Gbps copper connection between OSFP (IHS/Finned Top) to 4x QSFP56 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 HDR fabrics, HPC clusters and AI computing networks.

Applications
In InfiniBand HDR fabrics, HPC clusters and AI computing networks, the NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable provides a factory terminated 400Gbps link between OSFP (IHS/Finned Top) to 4x QSFP56 ports. This unit is delivered in 6 standard lengths from 0.5m (2ft) to 3m (10ft). One port becomes 4x QSFP56, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. It is interoperable with NVIDIA/Mellanox InfiniBand platforms and replaces the NVIDIA/Mellanox InfiniBand part MCP7Y70-H002 directly.
Standards and Compatibility
Compliance: OSFP MSA, IEEE 802.3cd, CMIS v4.0. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MCP7Y70-H002 directly, with identical fit and function. 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.
Ordering Information
The ordering part number is OSFP-400G-4QPC. We make this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Special lengths outside this range can be produced to order. Wire gauge: 28AWG.
Worldwide Delivery
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
Package
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.
Factory Custom Capability
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.
