1600Gb/s | OSFP to OSFP | 1.1m | RHS to RHS

Product Overview

The NVIDIA MCA4K00 (MPN: 980-9IAM4-00X001) is a state-of-the-art, 1.1-meter Active Copper Cable (ACC) built to serve as the physical backbone for next-generation AI pipelines, deep learning environments, and accelerated computing infrastructure. Supplying an enormous point-to-point throughput of 1600Gb/s (1.6Tb/s), this cable links ultra-dense network hardware across short distances with exceptionally low latency.

Powered by eight high-speed electrical lanes utilizing 200G-PAM4 modulation, the MCA4K00 features embedded active equalization circuitry. This allows it to reliably maintain optimal signal integrity over its 1.1-meter length, overcoming the physical limitations of legacy passive copper and offering a cost-effective alternative to optical transceivers.

Key Features

Massive 1.6Tb/s Throughput: Supports extreme data transfer rates across 8 lanes of high-frequency 200G-PAM4 technology.
Multi-Protocol Automation: Intelligent onboard firmware seamlessly auto-detects and activates InfiniBand (XDR), Ethernet, or NVL5 environments depending on the host device.
Symmetrical RHS-to-RHS Form Factor: Equipped with dual Riding Heat Sink (RHS / Flat Top) connectors on both ends, designed specifically for standard riding heat sink port cages.
Enhanced Signal Integrity (SI): Every cable length is individually tuned to combat internal signal noise, cross-talk, and back reflections, ensuring a rock-solid Bit Error Rate (BER).
