NVIDIA MCA4K50 Active Copper Cable

Name: NVIDIA MCA4K50 980-9IAM5-00X01A Active Copper Cable, 1600Gbps to 1600Gbps, OSFP, 1.5m, IHS to IHS
Brand: Nvidia
SKU: 6a4f4b8377e7b5368badcb25
Availability: InStock

1600Gb/s | OSFP to OSFP | 1.5m | IHS to IHS

Product Overview

The NVIDIA MCA4K50 (MPN: 980-9IAM5-00X01A) is a premium, high-density Active Copper Cable (ACC) engineered to drive the foundational network fabric of next-generation AI environments and high-performance computing (HPC) ecosystems. Delivering an outstanding point-to-point throughput of 1600Gb/s (1.6Tb/s), this 1.5-meter link enables high-capacity hardware to exchange massive datasets at bare-metal speeds with minimum latency.

Built on an architecture of eight high-speed electrical copper channels using advanced 200G-PAM4 modulation, the MCA4K50 features specialized onboard active signal conditioning. This provides stable multi-terabit transmission over an extended 1.5-meter reach, omitting the high power draw, thermal overhead, and steep costs associated with optical transceiver equivalents.

Key Features

Massive 1.6Tb/s Line Rate: Supports full wire-speed performance utilizing 8 independent channels of state-of-the-art 200G-PAM4 signaling.
InfiniBand XDR Tailored: Onboard firmware and equalization parameters are explicitly optimized to unleash the ultra-low latency potential of InfiniBand XDR fabrics.
Symmetrical IHS-to-IHS Form Factor: Features dual Integrated Heat Sink (IHS / Closed Finned Top) connectors on both ends, purpose-built to slide into finned-cage ports.
Extended 1.5-Meter Reach: Offers additional length flexibility over standard 1.1m variants, making it ideal for cross-rack architectures and complex routing topologies.
Active Equalization Integration: Active internal circuitry counteracts signal attenuation and jitter, ensuring a rock-solid Bit Error Rate (BER) across high-frequency interconnections.
