AI big data models, cloud computing, and massive data exchange are propelling data centers into the era of 800G high-speed interconnection. Traditional copper cables can't handle the load, discrete optical modules are too power-intensive, and cabling is messy and space-consuming—800G AOC active optical cables are becoming the true game-changer.

🔥 Three Major Pain Points in the 800G Era

Bandwidth Explosion: GPU clusters and east-west traffic surge, 400G is simply not enough.

Extreme Power Consumption: Traditional solutions suffer from severe heat generation, resulting in persistently high PUE.

Caching Nightmare: Heavy copper cables cause cabling management breakdowns in high-density data centers.

✨ Why is 800G AOC a Key Player?

800G full-speed transmission, supporting distances up to 100 meters, covering most data center scenarios.

Lower power consumption, saving 30%+ more power than ordinary optical module solutions, an essential for green data centers.

Lightweight fiber optic cable, easy to bend, high density, instantly clean and tidy cabling in the server room.

Plug and play, pre-integrated, fast deployment, fewer failures, and easier maintenance.

🖥 Core Application Scenarios

✅ AI intelligent computing clusters (GPU high-speed interconnect)

✅ Leaf-Spine architecture backbone links

✅ Distributed storage & HPC high-performance computing

✅ High-density interconnect for hyperscale data centers

Simply put:

In data center cabling, DAC cables (Direct Attach Copper) are becoming the top choice for in-rack interconnects thanks to their low cost, low power consumption, and high reliability! They require no separate optical modules and are plug-and-play, making them particularly suitable for short-distance 10G/25G/100G transmission. Want to save money while ensuring stability?

📌 What is DAC?

Copper cables with integrated transceiver modules, available in two types: passive (short distances, zero power consumption) and active (longer distances, signal compensation).

💡 Why Choose DAC?

✅ Cost-effective: Much cheaper than fiber optic module solutions

✅ Energy-efficient: Passive versions consume almost no power, and active versions use far less power than fiber optic modules

✅ Reliable: Electrical interfaces are dust-resistant and easy to maintain

✅ Fast: No electro-optical conversion means extremely low latency

🔧 How to choose?

1️⃣ Check the speed: Use SFP+ for 10G, SFP28 for 25G, and QSFP28 for 100G

2️⃣ Measure the distance: Choose passive for <5 meters, active for 5–10 meters

3️⃣ Check compatibility: When selecting third-party DAC-compatible cables, verify device brand compatibility
