제품 설명
NVIDIA MCA4J80-N005 800Gb/s OSFP Active Copper Cable
The NVIDIA MCA4J80-N005 is a 5-meter active copper cable (ACC) featuring a twin-port OSFP connector on one end and a 2x400Gb/s twin-port OSFP connector on the other. Designed for NVIDIA Quantum-2 InfiniBand and Spectrum-4 Ethernet switches, this ACC integrates pre-emphasis equalizer ICs to extend reach up to 5 meters while maintaining ultra-low latency and just 1.5W power per end.

Product Overview
The NVIDIA MCA4J80 series represents a new class of active copper cables (ACC) that bridge the gap between passive DACs and optical solutions. The MCA4J80-N005 uses integrated equalizer ICs at each end to compensate for signal degradation over longer copper runs, enabling 800Gb/s aggregate bandwidth at distances up to 5 meters with latency nearly as low as passive DACs.
Key Features
- 800Gb/s aggregate data rate – Twin-port OSFP to 2x400Gb/s OSFP configuration
- Active Copper Cable (ACC) – Integrated pre-emphasis equalizer ICs extend reach to 5 meters
- Ultra-low latency – Significantly lower than AOCs, nearly matching passive DAC performance
- Low power consumption – Just 1.5W maximum per end
- 5 meter length – 26AWG wire gauge, 8.9mm cable diameter
- Operating case temperature – 0°C to 70°C; storage -40°C to 85°C
- LSZH (Low Smoke Zero Halogen) jacket – RoHS compliant, Lead-free, Halogen-free PCB
- Hot-pluggable OSFP connectors – Finned top standard; flat top and flat-to-finned variants available
- Automatic protocol detection – Supports InfiniBand NDR and Ethernet 800GbE
- SFF-8636 compliant I²C management interface – EEPROM for product identification and configuration

Frequently Asked Questions
Q: What is the difference between ACC and passive DAC?
A: ACC adds low-power equalizer ICs at each end to compensate for signal loss, enabling longer reaches (5m vs. 2m for passive) while maintaining low latency and moderate power (1.5W per end).
Q: Is MCA4J80-N005 compatible with Ethernet switches?
A: Yes, the ACC firmware automatically detects InfiniBand or Ethernet protocol and configures accordingly. It works with Spectrum-4 Ethernet switches.
Q: What is the maximum length for this ACC series?
A: 5 meters (MCA4J80-N005). For lengths up to 2m, use passive DAC (MCP4Y10 series) for lowest power. For lengths beyond 5m, consider AOC or optical transceivers.
Buyer Checklist
- ✓ Required length: 3m, 4m, or 5m – ACC is optimal for distances beyond 2m up to 5m
- ✓ Connector type: finned for standard air-cooled switches; flat or flat-to-finned for DGX H100
- ✓ Protocol: InfiniBand or Ethernet – MCA4J80 auto-detects, no configuration needed
- ✓ Power budget: 1.5W per end – ensure switch can provide sufficient per-port power
- ✓ Cable management: Verify assembly space (156mm for combined end) fits rack door clearance
- ✓ Environmental: Confirm operating temperature range 0-70°C meets data center requirements
