NVIDIA MCA4K50 Active Copper Cable

Name: NVIDIA MCA4K50 980-9IAM3-00X003 Active copper cable, 1600Gbps to 1600Gbps, OSFP, 3m, IHS to IHS
Brand: Nvidia
SKU: 6a4f4d3774e210725f6e543f
Availability: InStock

1600Gb/s | OSFP to OSFP | 3m | IHS to IHS

Product Overview

The NVIDIA MCA4K50 (MPN: 980-9IAM3-00X003) is a high-performance Active Copper Cable (ACC) engineered to handle maximum data distribution requirements across large-scale AI, machine learning, and high-performance computing (HPC) infrastructures. Delivering a massive point-to-point throughput of 1600Gb/s (1.6Tb/s), this premium 3-meter cable establishes high-capacity fabric connections 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 3-meter reach, maximizing physical deployment range over standard passive copper limitations while bypassing the higher cost, power overhead, 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 unlock 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 slide seamlessly into finned-cage ports.
Extended 3-Meter Range: Provides the longest reach available in the active copper lineup, allowing for flexible multi-chassis routing, bottom-to-top rack wiring, and cross-rack switch clustering.
Active Equalization Integration: Active internal circuitry counteracts signal loss, cross-talk, and jitter, ensuring a clean Bit Error Rate (BER) across an extended copper length.
