Availability: InStock

1600Gb/s | OSFP to OSFP | 2m | IHS to IHS

Product Overview

The NVIDIA MCA4K50 (MPN: 980-9IAM3-00X002) is an ultra-high-performance Active Copper Cable (ACC) engineered to handle the massive data distribution needs of modern AI, machine learning, and high-performance computing (HPC) architectures. Providing a blazing point-to-point throughput of 1600Gb/s (1.6Tb/s), this premium 2-meter cable connects high-capacity fabric equipment seamlessly at bare-metal speeds.

Utilizing eight high-speed electrical copper lanes operating on advanced 200G-PAM4 modulation, the MCA4K50 incorporates onboard active signal conditioning. This enables stable multi-terabit transmission over an extended 2-meter reach, overcoming the strict distance and attenuation limits of passive copper while avoiding the higher cost, power consumption, and optical latency of transceivers.

Key Features

Massive 1.6Tb/s Line Rate: Supports full wire-speed performance across 8 independent channels utilizing next-generation 200G-PAM4 signaling.
InfiniBand XDR Tailored: Onboard firmware and signal equalizers are precision-tuned to unleash the ultra-low latency potential of InfiniBand XDR architectures.
Symmetrical IHS-to-IHS Form Factor: Features dual Integrated Heat Sink (IHS / Closed Finned Top) connectors on both ends, purpose-built to seamlessly slide into finned-cage ports.
Extended 2-Meter Reach: Offers ideal physical flexibility for multi-chassis deployments, complex routing, or cross-rack switch clustering without compromising signal integrity.
Active Equalization Integration: Active internal circuitry counteracts signal loss and jitter, guaranteeing a clean Bit Error Rate (BER) across extended copper lengths.
