Patch Panels - Their Functions
Patch panels can serve various functions based on their characteristics. The patch panel, also known as a cross-connect panel, is a passive device with multiple ports. Therefore, it is one of the most commonly used devices for cable management. There are two main types of panels: fiber optic patch panels and copper patch panels, each with distinct functionalities.
Primary Use of Patch Panels
As mentioned earlier, the primary purpose of a patch panel is cable management. It significantly improves cable organization and overall network management. Patch panels are often mounted in server racks and can connect hundreds or even thousands of different cables. Proper installation is crucial, as using a patch panel allows for reducing the cable bend angle, thereby extending its lifespan. The main task of a patch panel is to provide a robust and reliable solution for cable management and protection. However, it's essential to note that a patch panel serves as a physical connection only, lacking routers or additional switches.
Categories of Patch Panels:
Patch panels are categorized based on the types of cables they support:
Category 5e (Cat5e): Designed for Ethernet networks with speeds up to 1 Gb/s. It is a popular choice for many office and home networks.
Category 6 (Cat6): Allows speeds up to 10 Gb/s over shorter distances. Used in networks requiring higher bandwidth.
Category 6A (Cat6A): Provides bandwidth up to 10 Gb/s over longer distances than Cat6, characterized by better attenuation and shielding.
Shielding of Patch Panels:
Unshielded: More susceptible to external interference but a cheaper option suitable for applications with minimal risk of electromagnetic interference.
Shielded: Provides better protection against electromagnetic interference, crucial in environments with many electronic devices, industrial installations, or areas with strong electromagnetic fields.
Universal Unloaded Patch Panels
Universal unloaded patch panels are also gaining popularity. These panels have a simple frame with 24 or 48 empty ports, designed for Keystone jack modules. Installation is straightforward, involving placing the cable into the module and connecting it to the empty slot on the panel. This design allows for easy correction of each connection. It is important to note that loaded panels require removal from the cabinet for any corrections, which can be challenging, especially when numerous cables are connected, and the panel is hidden in the cabinet.
In summary, patch panels offer a convenient solution for better space utilization, cable organization, and protection. The choice of a specific patch panel depends on the network's needs, data transfer speed, distance requirements, and the environment in which they are used.
