T568A vs. T568B – Which Ethernet Standard Should You Use?

T568A vs. T568B – Which Ethernet Standard Should You Use?

Network Engineers, IT Pros, and Tech Enthusiasts!

If you’ve ever crimped an Ethernet cable, you’ve likely encountered the T568A and T568B wiring standards. While both achieve the same performance, choosing the right one can impact compatibility and best practices in structured cabling.

T568A – Preferred for government, residential, and legacy systems.
T568B – The most widely used in commercial networks.

Key Takeaway:

Use T568B for most modern setups.

Stick to T568A if you’re expanding an existing T568A network.

If you’re making a crossover cable, one end should be T568A and the other T568B (though Auto-MDIX has made these less necessary).
