Ethernet Cables Explained: Stop Overbuying the Wrong Cable
Everyone wants the fastest network until it’s time to pay for it.
The truth? Most businesses don’t need Cat8. Most networks aren’t limited by cable. They’re limited by poor design, bad terminations, outdated switches, and unmanaged infrastructure.
Quick Breakdown
🔹 Cat5
* Up to 100 Mbps
* Legacy installations
* Replace when possible
🔹 Cat5e
* Up to 1 Gbps
* Still widely deployed
* Perfectly usable for many businesses
🔹 Cat6
* Supports 1 Gbps and can handle 10 Gbps over shorter distances
* Great for offices, retail, POS, and surveillance
🔹 Cat6A
* Supports 10 Gbps up to 100 meters
* Current recommendation for new commercial deployments
* Best balance of cost and performance
🔹 Cat7
* Rarely used in North America
* Limited practical advantage over Cat6A
* Often marketed more than deployed
🔹 Cat8
* Designed for data centers
* Supports 25G/40G networking
* Overkill for most offices, homes, and retail locations
What We Recommend
At SABITX, our standard approach is simple:
✅ Cat6A for new infrastructure
✅ Fiber between buildings and network closets
✅ Enterprise-grade switching and power protection
✅ Proper testing, labeling, and documentation
Because a well-designed Cat6A network will outperform a poorly installed Cat8 network every single day.
Technology isn’t about buying the most expensive cable.
It’s about building systems that work when the business depends on them.
