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), engineered for InfiniBand NDR and Ethernet networks. It delivers ultra-low latency and power efficiency, making it an ideal solution for high-density data center environments.
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 minimal power consumption (1.5W per end)
- Hot-pluggable, RoHS compliant, and LSZH jacket for improved safety
- Compatible with both InfiniBand NDR and Ethernet protocols
Technology Overview
The MCA4J80 ACC utilizes 100G-PAM4 modulation across 8 channels per port. It features pre-emphasis equalization to extend cable reach while ensuring signal integrity. The cable is compliant with OSFP MSA Rev. 1.12 and supports SFF-8636 I²C management for real-time monitoring and identification.
How It Works
Each end of the cable incorporates an equalizer IC that compensates for signal attenuation and distortion, enabling stable data transmission over extended distances. An embedded EEPROM stores product identification and characteristics, allowing the host system to auto-configure the cable based on the connected switch protocol.
Applications
- Switch-to-switch connectivity in NVIDIA Quantum-2 InfiniBand and Spectrum-4 Ethernet environments
- Connecting NVIDIA DGX-H100 Cedar systems to top-of-rack switches
- High-performance computing (HPC), artificial intelligence (AI), and machine learning (ML) clusters
