The $2.1 Billion Question: Why Active Copper Cables Are the Unsung Heroes of the AI Data Center Boom

Introduction

Every time you stream a video, send an email, or ask an AI chatbot a question, your data travels through miles of copper cable. Not fibre optics. Not wireless. Copper.

The global copper wire and cable market was valued at USD 182.0 billion in 2025 and is projected to reach USD 324.7 billion by 2032, growing at a compound annual growth rate (CAGR) of 8.6%. Within this vast market, one segment is experiencing particularly explosive growth: active copper cables (ACC) .

The global active copper cables market was valued at approximately USD 2.1 billion in 2024 and is expected to reach USD 3.8 billion by 2031, growing at a CAGR of 7.8%. The DAC (Direct Attach Copper) active copper cable market alone was valued at USD 1.102 billion in 2025 and is forecast to reach USD 1.859 billion by 2032, with a CAGR of 7.3%.

Why is this happening? And why should you care?

This article explores the active copper cable market—what it is, why it is growing so rapidly, and what the future holds for this critical but often overlooked technology.

What Is an Active Copper Cable?

Before we dive into the numbers, let us establish what an active copper cable actually is.

An Active Copper Cable (ACC) is a high-speed copper-based interconnect solution that integrates active signal conditioning components—such as retimers, equalizers, or driver ICs—into traditional copper cables.

This is a critical distinction from passive copper cables. Passive cables simply transmit signals without any active electronics. They work well for short distances and lower speeds. But as data rates climb into the hundreds of gigabits per second, passive cables face a fundamental problem: signal attenuation.

At high speeds, electrical signals degrade rapidly over copper. Crosstalk between adjacent wires increases. Bit error rates rise. Passive cables simply cannot maintain signal integrity at 400G, 800G, or beyond.

Active copper cables solve this problem by embedding electronics that compensate for signal attenuation and crosstalk in copper media, enabling higher data rates and longer reach while maintaining the advantages of copper: low latency, low power consumption, and cost efficiency.

Active Copper Cable vs. Passive DAC vs. AOC vs. AEC

To understand the ACC market, it helps to understand where it fits in the connectivity ecosystem:

Active copper cables occupy a sweet spot: longer reach than passive DACs, lower cost and power than AOCs, and comparable performance to AECs at a lower price point. This makes them particularly attractive for high-bandwidth links in the 2–5 metre range.

The Growth Drivers: Why Active Copper Cables Are Booming

1. The AI Data Center Explosion

The single biggest driver of the active copper cable market is the explosive growth of AI data centres.

AI workloads are massively compute-intensive. They require thousands of GPUs working in parallel, all communicating with each other at extremely high speeds. The training of large language models (LLMs) like GPT-4, Claude, and Gemini requires clusters of tens of thousands of GPUs, all connected in a high-speed fabric.

These clusters generate enormous bandwidth requirements. The connections between GPUs, between GPUs and switches, and between switches and storage must operate at 400G, 800G, and soon 1.6T.

Passive DACs simply cannot handle these speeds over the required distances. Active copper cables can.

According to industry analysis, the medium-term AI outlook is strong, with active cables expected to extend copper’s viability into 448G, delaying the transition to optics or co-packaged optics (CPO).

2. High-Speed Ethernet Upgrades

Data centres are rapidly upgrading from 100G and 400G to 800G and 1.6T Ethernet. As the deployment of 400G and 800G ports accelerates, passive DACs face limitations in reach and signal integrity, positioning active copper cables as a critical short-reach interconnect option.

3. Increasing Compute Density

Cloud data centres are becoming denser. More servers, more GPUs, more storage devices are packed into the same physical space. This increases the number of interconnects required and the speed at which they must operate.

Active copper cables provide a low-power, low-total-cost-of-ownership (TCO) solution for these dense environments.

4. Cost and Power Advantages

Active copper cables offer clear advantages over alternatives:

• Compared to AOCs: ACCs are significantly cheaper and consume less power

• Compared to AECs: ACCs are simpler to deploy and often more cost-effective for shorter reaches

• Compared to passive DACs: ACCs support higher speeds and longer reaches

5. Telecommunications and 5G

Beyond data centres, the telecommunications sector is a major consumer of active copper cables. The rollout of 5G networks, the expansion of broadband infrastructure, and the growth of IoT all require reliable, high-speed copper cabling.
