Keystone: Empty panels with slots where you can snap in whichever modular jack you need separately (e.g., Cat6, telephone, HDMI), offering complete flexibility.
Shielded: Shielded panels that protect the network from interference (noise) from other cables or devices, ideal for professional datacenters.
Unshielded: Unshielded panels for simple, standard networks (UTP) where there are no nearby sources of strong electromagnetic interference.
Panel Cover: Blank panels installed in the rack to cover gaps, improving aesthetics and proper airflow.
Optical: Special panels (Fiber Patch Panels) designed exclusively for the termination and management of fiber optic cables.
Brush Panel: Panels with integrated brush strips that allow cables to pass from inside the rack to the outside while keeping dust out.
Telephone: Panels with multiple ports (usually RJ11/RJ12), optimized for the aggregation and management of a building’s telephone lines.
