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
The NVIDIA InfiniBand Compatible 400G OSFP 8x 50G PAM4 to 2x 200G QSFP56 4x 50G PAM4 InfiniBand HDR Passive Breakout DAC Cable is a 400Gbps direct attach copper cable for OSFP to 2x QSFP56 connections in InfiniBand HDR fabrics, HPC clusters and AI computing networks. This unit is made 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.
Standards and Compatibility
Compliance: OSFP MSA, CMISRev4.0, IEEE802.3cd, SFF-8436, SFF-8665, SFF-8679, SFF-8636. For projects standardized on NVIDIA/Mellanox InfiniBand hardware, this product replaces the MCP7Y60-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.
Ordering Information
The part number for this assembly is OSFP-400G-2QPC. We offer this cable in 1m (3ft), 1.5m (5ft) and 2m (7ft). Other lengths can be custom manufactured on request. Wire gauge: 28AWG.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
How We Ship
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.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
