Generative Artificial Intelligence (AI), with its potential to transform several industries, has been making waves since the release of ChatGPT in late 2022. As a consequence, the immense need for data, its inference and transformation has put new demands on data center infrastructure. AI clusters today demand larger neural networks, which means more hardware and more power consumption. This requires solutions that not only provide better networking through lower latency but also cost versus power optimization and easier hardware management.
Data center servers and networking equipment rely on copper cables for making connections within a rack and between racks. These cables, called Direct Attach Copper (DAC) cables, have traditionally been passive in nature and were able to meet data center needs. However, with the advent of Generative AI, hyperscalers are pushing for signal speeds at 112Gbps with PAM4 signal modulation and beyond to meet the high-bandwith requirements between AI servers. At such high data transfer rates, passive DACs fail to meet the Signal Intregity (SI) requirements. Moreover, a significant increase in the volume of DACs within a rack makes cable management a cumbersome task from a bend radii and heat dissipation perspective. Hence, data centers are transitioning from passive DACs to active cable solutions.

1. What Is AEC?
Active Electrical Cable (AEC) is a next-generation copper cable that integrates an active electronic circuit inside its connector to amplify and equalize signals during high-speed transmission.
Unlike traditional passive copper cables, AEC enables 10G to 400G Ethernet performance over extended distances without switching to fiber.
With Heizka AEC – From USA, data center engineers can achieve the perfect balance between cost efficiency, high performance, and reliability that meets international standards.

2. Key Advantages of Heizka AEC
- High-Speed, Low-Latency Transmission: Supports 10G / 25G / 40G / 100G / 400G Ethernet across SFP, QSFP, or OSFP interfaces.
- Longer Reach than DAC: Stable data transmission up to 7 meters with minimal signal loss.
- Integrated Smart Amplifier: Built-in equalizer and retimer chip to reduce EMI and optimize signal integrity.
- Plug-and-Play Compatibility: Works seamlessly with Cisco, Dell, Arista, Juniper, and other major switch brands.
- No External Power Required: Fully self-powered from the transceiver interface.
- Industrial-Grade Durability: Fire-resistant LSZH jacket with superior shielding, perfect for dense rack environments.
3. Applications in Data Centers
AEC cables are designed for high-performance data center architectures such as:
- Top-of-Rack (ToR) and End-of-Row (EoR) interconnections.
- Switch-to-Switch or Switch-to-Server links running 25G/40G/100G.
- Cost-effective alternative to short-range fiber, maintaining high signal integrity.
- AI servers, HPC clusters, and monitoring systems demanding reliable high-bandwidth connections.
Heizka’s AEC portfolio is engineered to integrate seamlessly with intelligent PDUs, patch panels, and rack monitoring systems, forming a complete ecosystem for smart data centers.
