Q: What’s the difference between Shielded and Unshielded Ethernet Ports? Do I need a Shielded Port?

A: Shielded Ethernet cables and ports are typically used when there is high electromagnetic power presence that will interfere with communication. This is oftentimes found in welding applications. Typically if you are not aware that you have a high EMI (Electro-Magnetic Interference) environment, you will not need the shielded port or cable.
