What is the primary purpose of shielding in STP cables?

Shielding in STP cables is designed to block external electromagnetic interference from sources outside the cable, protecting the signal inside. The metallic shield acts as a barrier, and when grounded it provides a path to bleed off noise, improving resistance to EMI and reducing errors in noisy environments. This is about maintaining signal integrity rather than changing how much the signal weakens over distance, and it isn’t related to color coding or patch cord length.
