Description

The NVIDIA 980-9I99F-00H002 is a 200Gb/s to 2x100Gb/s passive copper breakout cable designed for high-density data center connectivity. This 2-meter direct attach copper cable splits one QSFP56 port into two QSFP56 ports, supporting both 200G Ethernet and InfiniBand HDR applications. Ideal for short-reach spine-leaf architectures, AI/ML clusters, and high-performance computing environments requiring cost-effective, low-power interconnects.

Features

200Gb/s to 2x100Gb/s PAM4 breakout topology for flexible bandwidth allocation
- Passive copper twinax construction with ultra-low power consumption (<0.15W)
- Hot-swappable QSFP56 connectors with integrated EEPROM for auto-detection
- Supports IEEE 802.3cd 200GBASE-CR4 and 100GBASE-CR2 Ethernet standards
- InfiniBand HDR (200Gb/s) and HDR100 (2x100Gb/s) compatibility
- 26 AWG gauge for optimal signal integrity and flexibility in dense racks
- LSZH fire-rated jacket for compliance with data center safety standards
- Compliant with SFF-8665 and QSFP56 MSA mechanical and electrical specifications
- Zero external power requirement eliminates heat generation and complexity
- Suitable for spine-leaf, AI/HPC, and high-density server-to-switch connectivity
- Wide operating temperature range: 0Ā°C to 70Ā°C
- Pull-tab design for easy insertion and removal in high-port-density environments

FAQs

Q: What is the difference between this passive DAC and an active optical cable (AOC)?
A: Passive DAC cables use copper twinax conductors with no active components, consuming minimal power (<0.15W) and offering excellent cost-effectiveness for short distances up to 3 meters. AOCs use optical fiber with integrated transceivers, suitable for longer distances (7-100m+) but at higher cost and power consumption. For 2-meter connections, passive DAC is the optimal choice.

Q: Can this cable be used to connect 100G QSFP28 network cards?
A: No. This QSFP56 breakout cable uses 2x50G PAM4 modulation per 100G port, while QSFP28 uses 4x25G NRZ modulation. You need network adapters or switches with native QSFP56 100G ports that support PAM4 signaling. Standard QSFP28 ports are not compatible.

Q: Does my switch need to support breakout mode for this cable?
A: Yes. The 200G QSFP56 port must be configured in breakout mode (typically 1x200G to 2x100G) to recognize and utilize both 100G endpoints. Most modern NVIDIA/Mellanox Spectrum, Quantum InfiniBand, and compatible switches support this configuration via CLI or management interface.

Q: Is this cable compatible with NVIDIA Spectrum and Quantum switches?
A: Yes. This cable is designed for NVIDIA Spectrum-2, Spectrum-3, and Spectrum-4 Ethernet switches, as well as Quantum InfiniBand HDR switches (QM8700, QM9700 series). It is also compatible with other vendors' MSA-compliant QSFP56 ports that support 200G and breakout functionality.

Q: What is the maximum recommended length for passive copper breakout cables?
A: Passive copper DAC cables are recommended for lengths up to 3 meters. Beyond this distance, signal integrity degrades. For longer reach (5-100+ meters), consider active optical cables (AOC) or active equalization copper (AEC) cables with integrated signal conditioning.
