NVIDIA MCA4J80-N005 800Gb/s OSFP Active Copper Cable 5m for High-Speed Data

The NVIDIA MCA4J80-N005 is an 800Gb/s twin-port OSFP to 2x400Gb/s OSFP Active Copper Cable designed for high-performance InfiniBand NDR networking. This advanced network card delivers exceptional bandwidth while maintaining minimal latency and power consumption, making it ideal for data-intensive applications in modern data centers.

As a high-performance network interface card, the MCA4J80-N005 provides reliable connectivity solutions for enterprise networks, HPC clusters, and AI infrastructure. With its innovative design and robust construction, this NIC card ensures stable data transmission across extended distances while optimizing power efficiency.

• 800Gb/s total bandwidth with twin-port OSFP configuration
• Active Copper Cable technology with integrated equalizer ICs
• Extended 5-meter reach with minimal signal degradation
• Low power consumption at 1.5W per end
• Hot-pluggable design for easy installation and maintenance
• Compliant with InfiniBand NDR and Ethernet standards
• RoHS compliant with LSZH (Low Smoke Zero Halogen) jacket
• Support for both InfiniBand and Ethernet protocols

The MCA4J80-N005 network card utilizes advanced 100G-PAM4 modulation across 8 channels to achieve its high data rates. The active copper cable design incorporates equalizer integrated circuits at both ends, which extend signal integrity over longer distances compared to passive DAC cables.

This NIC card complies with OSFP MSA Specification Rev. 1.12 and implements SFF-8636 based I²C management interface for comprehensive device monitoring and control. The sophisticated firmware automatically detects and adapts to the connected switch protocol, supporting both InfiniBand and Ethernet environments without manual configuration.

The Active Copper Cable functions by integrating signal conditioning electronics directly into the cable assembly. Each end contains equalizer ICs that compensate for signal attenuation and distortion that naturally occurs in copper conductors over distance. This active componentry enables the cable to maintain signal integrity across extended lengths up to 5 meters while preserving the low-latency characteristics of copper interconnects.

The embedded EEPROM in each connector provides vital product identification and characteristic data to the host system, enabling automatic configuration and compatibility verification. When connected, the system reads this information to ensure optimal performance settings are applied for the specific cable type and length.

The MCA4J80-N005 network card is engineered for high-performance computing environments requiring maximum bandwidth and minimal latency:

• Interconnecting Quantum-2 InfiniBand switches in data center environments
• Linking Spectrum-4 Ethernet switches for high-speed networking
• Connecting Quantum-2 switches to DGX-H100 Cedar systems
• High-performance computing clusters and AI training infrastructure
• Data center spine-leaf architectures requiring high-bandwidth interconnects

The MCA4J80-N005 network card delivers significant advantages over alternative connectivity solutions:

• Cost Efficiency: Provides the second lowest-cost high-speed connectivity solution after passive DAC cables, offering excellent value for performance.
• Extended Reach: Enables cable lengths up to 5 meters while maintaining signal integrity, surpassing the limitations of passive copper solutions.
• Power Optimization: Consumes only 1.5W per end, significantly less than optical transceivers, reducing overall power consumption in data centers.
• Low Latency: Maintains the inherent low-latency characteristics of copper interconnects while extending usable distance.
• Dual Protocol Support: Automatically adapts to both InfiniBand and Ethernet environments without requiring manual configuration changes.
