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.

Product Highlights

• OSFP (IHS/Finned Top) to 4x QSFP56
• Data rate: 400Gbps
• Cable type: Passive Twinax
• Length: standard options (6) from 0.5m (2ft) to 3m (10ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

The NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 4x 100G QSFP56 2x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable connects OSFP (IHS/Finned Top) to 4x QSFP56 ports at 400Gbps in InfiniBand HDR fabrics, HPC clusters and AI computing networks. This unit is manufactured in 6 standard lengths from 0.5m (2ft) to 3m (10ft). The breakout design lets one high speed port feed 4x QSFP56, which raises port utilization and simplifies cabling in dense rows. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MCP7Y70-H002. The link runs 8x 50G-PAM4 to Quad 2x 50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox InfiniBand part MCP7Y70-H002 and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers OSFP MSA, IEEE 802.3cd, CMIS v4.0.

Part number of this model: OSFP-400G-4QPC. Length options are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft) and 3m (10ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.

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.

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.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.
