Product Overview

The NVIDIA MCA4K50 (MPN: 980-9IAM5-00X001) is a flagship, ultra-high-density Active Copper Cable (ACC) specifically engineered to orchestrate the backend fabric of next-generation AI pipelines and high-performance computing (HPC) ecosystems. Providing a staggering point-to-point throughput of 1600Gb/s (1.6Tb/s), this premium 1.1-meter link allows high-capacity data center devices to communicate seamlessly at bare-metal speeds.

Utilizing eight high-speed electrical copper pairs operating on advanced 200G-PAM4 modulation, the MCA4K50 features specialized onboard active signal conditioning. This enables stable multi-terabit transmission over its 1.1-meter length without the significant power draw, thermal overhead, and premium cost associated with traditional optical transceivers.

Key Features

Massive 1.6Tb/s Line Rate: Supports full wire-speed performance utilizing 8 independent channels of state-of-the-art 200G-PAM4 technology.
InfiniBand XDR Optimized: Onboard firmware is explicitly tailored and tuned to unleash the full potential of low-latency InfiniBand XDR architecture.
Symmetrical IHS-to-IHS Form Factor: Equipped with dual Integrated Heat Sink (IHS / Closed Finned Top) connectors on both ends, purpose-built to slide into finned-cage ports.
Active Equalization Integration: Active internal circuitry counteracts signal attenuation and jitter, guaranteeing a pristine Bit Error Rate (BER) across high-frequency interconnections.
