Product Description
MCA4J80-N005 800Gb/s OSFP Active Copper Cable (ACC)
The NVIDIA® MCA4J80 is a high-performance, twin-port OSFP to 2x400Gb/s OSFP Active Copper Cable (ACC) designed for InfiniBand NDR and Ethernet networking. It delivers ultra-low latency and power efficiency, making it ideal for high-density data center environments.
MCA4J80-N005 Key Features
- 800Gb/s total bandwidth with 2x400Gb/s bidirectional ports
- Active Copper Cable (ACC) technology with integrated equalizer IC
- Supports lengths up to 5 meters with very low power consumption (1.5W per end)
- Hot-pluggable, RoHS compliant, and LSZH jacket for enhanced safety
- Compatible with InfiniBand NDR and Ethernet protocols
MCA4J80-N005 Technology
The MCA4J80 ACC utilizes 100G-PAM4 modulation across 8 channels per port. It incorporates pre-emphasis equalization to extend cable length while maintaining signal integrity. The cable is compliant with OSFP MSA Rev. 1.12 and supports SFF-8636 I²C management for real-time monitoring and identification.
MCA4J80-N005 Working Principle
Each end of the cable includes an equalizer IC that compensates for signal attenuation and distortion, enabling reliable data transmission over longer distances. The embedded EEPROM stores product identification and characteristics, allowing the host system to automatically configure the cable based on the connected switch protocol.
Applications
- Switch-to-switch connectivity in NVIDIA Quantum-2 InfiniBand and Spectrum-4 Ethernet environments
- Linking NVIDIA DGX-H100 Cedar systems to top-of-rack switches
- High-performance computing (HPC), artificial intelligence (AI), and machine learning (ML) clusters
