patch panel concept

patch panel management subsystem is the most important component, is to achieve two vertical lines and horizontal cabling subsystem cross-connect hub. MDF is usually installed in a cabinet or on the wall. By mounting accessories, patch panels can be across the board to meet UTP, STP, coaxial cable, fiber, audio and video needs. Commonly Plug-in terminal block
  used in network engineering has UTP patch panels and fiber optic patch patch. Fiber optic patch panel's role in the management of the cable will be connected subsystems, usually between the main line and the line between the various distribution. MDF industry standard definition: patch panel-- suitable for wiring devices jumper connections. It enables the system to move and change the wiring is more convenient. cross-connect system patch panel-- managed by a convenient form of pairs of connectors. Twisted role in the management of patch panel in the twisted-pair cross-connect subsystems used in each room and the distribution line of the main wiring. Many models UTP patch panels, each vendor has its own product line, and the corresponding cat5e network cable three categories, Category 5, Category 5e, Category 6 and Category 7 cables were different sizes and models, in specific projects , you should refer to the product manual, be configured according to the actual situation. Fiber optic patch panel's role in the management of the cable will be connected subsystems, usually between the main line and the line between the various distribution
