NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable

The NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable provides a 400Gbps copper connection between OSFP to 2x 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.

Product Highlights

• OSFP to 2x QSFP56
• Data rate: 400Gbps
• Cable type: Passive Twinax
• Length: 3 standard lengths between 1m (3ft) to 2m (7ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

Designed for InfiniBand HDR fabrics, HPC clusters and AI computing networks, the NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable carries 400Gbps between OSFP to 2x QSFP56 interfaces. This unit is provided in 3 standard lengths from 1m (3ft) to 2m (7ft). By fanning one port out to 2x 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 MCP7Y60-H002.

On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox InfiniBand part MCP7Y60-H002 and works in NVIDIA/Mellanox InfiniBand systems out of the box. Standards compliance covers OSFP MSA, CMISRev4.0, IEEE802.3cd, SFF-8436, SFF-8665, SFF-8679, SFF-8636.

This assembly is listed under part number OSFP-400G-2QPC. The cable is supplied in 1m (3ft), 1.5m (5ft) and 2m (7ft). Custom lengths beyond the standard range are available on request. Wire gauge: 28AWG.

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.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

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.

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.
