What are the differences between UTP Cat 5e, vs Cat 6 and so on….
Here's a clear, structured comparison of UTP Cat 5e vs Cat 6, Cat 6A, Cat 7, and Cat 8, so you can understand their key differences and applications — especially relevant for high-speed networks like Wi-Fi 7 and future-ready infrastructure.
``` 📊 Comparison Table: UTP Ethernet Cables
*Note: Cat 7 often uses non-standard connectors like GG45 or TERA, making compatibility with normal RJ45 equipment limited.
📌 Key Differences Explained
1. Cat 5e (Enhanced Category 5)
Suitable for 1 Gbps Ethernet.
Max length 100 meters.
Most affordable, but becoming outdated.
Fine for basic home or office use — not recommended for future-proofing.
2. Cat 6
Designed for 10 Gbps, but only up to 55 meters.
Runs 2.5 or 5 Gbps comfortably over 100m.
Ideal for Wi-Fi 6 or Wi-Fi 7 backhaul, if cable runs are within distance limits.
Usually UTP, but can be shielded.
3. Cat 6A (Augmented)
Handles 10 Gbps at full 100m, thanks to improved shielding and insulation.
Higher bandwidth (500 MHz) and less crosstalk.
Best choice for future-proofing — ideal for smart homes, buildings, and high-density PoE use.
Slightly thicker and stiffer than Cat 6.
4. Cat 7
Always shielded (S/FTP) for superior EMI protection.
Often uses non-standard connectors, limiting consumer compatibility.
Still capped at 10 Gbps, but with better shielding than Cat 6A.
Overkill for most home setups — better in data centers.
5. Cat 8
For data center/server room short runs.
Up to 40 Gbps, but only 30 meters max.
Expensive and typically not necessary for home or office unless doing heavy server/data work.
