A shielded patch panel comes with a conductive layer that protects against electromagnetic interference (EMI) and radio frequency interference (RFI). This conductive layer is usually made of braided mesh or foil. It gives your cables a safer path so your connection stays steady. The design supports higher-speed runs. In real racks, shielding only works when the whole Ethernet channel (cable + jacks + patch panel + bonding) is treated as one system. Today, various styles of copper patch panels can be found in the market, such as shielded or unshielded patch panel, flat or angled patch panel, etc.
