Shielded copper is chosen when electromagnetic interference could affect the signal. The shield acts as a barrier that steers noise away from the conductors, but it only works well if the shield is properly grounded at least at one end and continuity is maintained through terminations. The benefit is clearest on longer cable runs, where more interference can accumulate, and when the run is near strong noise sources like power lines. Using shielded connectors helps preserve that shielding as the cable ends are connected, keeping the protection intact. In contrast, short, low-noise office runs don’t usually need shielding, and outdoor runs without proper grounding would not gain EMI protection and could introduce other issues. So the best situation for shielded copper is high-EMI environments or longer runs near power lines, with shielded connectors.
