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 is a passive twinax direct attach copper cable with OSFP to 2x 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, CMISRev4.0, IEEE802.3cd, SFF-8436, SFF-8665, SFF-8679, SFF-8636.

Applications
In 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 provides a factory terminated 400Gbps link between OSFP to 2x QSFP56 ports. This unit is delivered in 3 standard lengths from 1m (3ft) to 2m (7ft). One port becomes 2x QSFP56, a common pattern for connecting newer aggregation ports to an installed base of lower speed equipment. For networks standardized on NVIDIA/Mellanox InfiniBand hardware, it is a drop-in equivalent of the MCP7Y60-H002.
Standards and Compatibility
This product is designed and tested to comply with OSFP MSA, CMISRev4.0, IEEE802.3cd, SFF-8436, SFF-8665, SFF-8679, SFF-8636. It is interoperable with NVIDIA/Mellanox InfiniBand equipment and serves as a direct equivalent to the NVIDIA/Mellanox InfiniBand part number MCP7Y60-H002.
Ordering Information
The ordering part number is OSFP-400G-2QPC. We make this cable in 1m (3ft), 1.5m (5ft) and 2m (7ft). Special lengths outside this range can be produced to order. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.
Packaging
Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
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.
Tested Before Shipment
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.
