NVIDIA 980-9I949-00N005 | 800G to 2x400G Active Copper Splitter, OSFP to 2xOSFP, 5m

Q: What is the primary use case for this splitter cable?
A: This cable connects a single 800Gb/s port on an NVIDIA Quantum-2 or Spectrum-4 switch to two ConnectX-7 network adapters operating at 400Gb/s each, enabling efficient dual-endpoint connectivity in data centers and HPC environments.

Q: What is the difference between active copper cable (ACC) and passive DAC?
A: ACC cables include integrated equalization circuits to extend reach beyond passive DAC capabilities while maintaining lower power consumption and latency compared to optical cables. This 5-meter ACC supports signal integrity at longer distances than passive copper alternatives.

Q: Is this cable compatible with both InfiniBand and Ethernet protocols?
A: Yes, the cable firmware automatically detects and supports both InfiniBand NDR and Ethernet protocols based on the switch it is connected to, providing flexible deployment options.

Q: What AWG rating does this cable use?
A: This 5-meter splitter cable uses 28 AWG copper conductors with LSZH jacketing, balancing flexibility, performance, and fire safety requirements for data center installations.

Q: Can this cable be used in liquid-cooled systems?
A: The flat-top OSFP connectors on the 400G ends are designed for use with ConnectX-7 adapters in both air-cooled and liquid-cooled systems. Specific flat-top variants are available for specialized liquid-cooled deployments.
