The NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable is a passive twinax direct attach copper cable with OSFP (IHS/Finned Top) to 4x QSFP56, supporting 400Gbps 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 HDR fabrics, HPC clusters and AI computing networks, and complies with OSFP MSA, IEEE 802.3cd, CMIS v4.0.

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 produced in 6 standard lengths from 0.5m (2ft) to 3m (10ft). By fanning one port out to 4x QSFP56, it doubles or quadruples the number of endpoints served per switch port and keeps the cabling plant simple. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MCP7Y70-H002.
Standards and Compatibility
This product is designed and tested to comply with OSFP MSA, IEEE 802.3cd, CMIS v4.0. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MCP7Y70-H002.
Ordering Information
The factory part number is OSFP-400G-4QPC. This cable is available in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 28AWG. Volume pricing is available for project quantities.
Our Testing Process
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.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
Customization Service
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.
Logistics
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.
