2m/6.56ft 800G OSFP to 2x400G QSFP112 DAC Breakout Cable, Finned-Top to Flat-Top Passive Direct Attach Copper Twinax, Compatible with NVIDIA Quantum-2, Spectrum-4, 8x100G PAM4 to 4x100G PAM4

800G TO DUAL 400G BREAKOUT CONNECTIVITY Designed to connect one compatible 800Gbps OSFP switch port to two 400Gbps QSFP112 ports. Supports 8×100G PAM4 lanes on the OSFP side and 4×100G PAM4 lanes per QSFP112 branch, enabling high-bandwidth connections for AI computing clusters, H-PC systems and data center networks.
COMPATIBLE WITH NVIDIA NETWORKING SYSTEMS Designed for compatible NVIDIA Quantum-2 InfiniBand and Spectrum-4 Ethernet switch applications, connecting to QSFP112-based ConnectX-7 network adapters and BlueField-3 DPUs. Device firmware, port configuration and cable EEPROM coding must support the required breakout mode.
2M PASSIVE DIRECT ATTACH COPPER CABLE This 2-meter (6.56ft) passive twinax breakout cable provides short-range connectivity between adjacent racks, switches and servers. Its passive copper design eliminates the need for separate optical transceivers or external power supplies, making it suitable for high-density data center installations.
FINNED-TOP OSFP TO DUAL FLAT-TOP QSFP112 Features one 800G OSFP finned-top connector for compatible switch cages and two 400G QSFP112 flat-top connectors for supported network adapters and DPUs. The specialized connector design is intended for equipment with matching port form factors and cooling configurations.
HIGH-SPEED AI & DATA CENTER APPLICATIONS Suitable for compatible 800G-to-2×400G Ethernet or InfiniBand breakout deployments, including AI training infrastructure, GPU server interconnects, H-PC networks and high-bandwidth data center environments. Actual link speed and operation depend on host compatibility, supported protocols, EEPROM coding and switch port configuration.
