NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable

For short reach 400Gbps links 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 offers a factory terminated passive twinax assembly with OSFP (IHS/Finned Top) to 4x QSFP56 connectors and a length of 2m (7ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets OSFP MSA, IEEE 802.3cd, CMIS v4.0.

Designed for 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 carries 400Gbps between OSFP (IHS/Finned Top) to 4x QSFP56 interfaces. This unit is available 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. It is interoperable with NVIDIA/Mellanox InfiniBand platforms and replaces the NVIDIA/Mellanox InfiniBand part MCP7Y70-H002 directly.

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.

The standard part number of this assembly is OSFP-400G-4QPC. 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.

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.

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.

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.
