|
Detailed Product Description
|
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. 800 Gb/s Aggregate bandwidth 2x400G Full duplex 1.5W Power per end 5m Maximum length 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

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
