The main categories of 12 port patch panel

Positioning 12 port patch panel is in front of the central office of information points modular device management. The front of the information point cable (Cat5e or 6 cable) into the equipment room after the first into patch panels, patch panels will hit the line modules, patch panels and switches then connect a jumper (RJ45 interface) . Overall, the patch panel is rj45 keystone jack  used to manage the device, for example, if there is no patch, direct access to the front of the information points to the switch, so that once the cable problems, faced to rewiring. In addition, the management is also a bit confusing, multiple plug may cause damage to the switch port. MDF exist to solve this problem by replacing the jumper to achieve better management.
12 port patch panel Dosage and overall network is mainly based on the number of points or the floor (and similar floor, depending on how the system is designed diagram) points to the number of network configurations. Different buildings, different system designs, patch panels are the main differences between the devices. For example, a building only four rooms, the barrier terminal block  master device is set on the first floor, all floors between network points are entering the device, then the patch is equal to the number of the building all network points / patch panel port number (24 mouth, 48, etc.), plus got to margin; If, on the 9th floor of a building has a room, the master device is set on the fourth floor, then in order to avoid long cable, it may partakers devices are located on each floor , and there is exchange equipment. So the main distribution frame between devices on the network is  rca video cable equal to the number of points / patch panel ports (24, 48, etc.) 4 layers. Most 12 port patch panel UTP patch panels are used for horizontal wiring. The front panel assembly line equipment used to connect an RJ-45 port on the rear panel for connecting twisted-pair extending from the information outlet over. UTP patch panels are mainly 24 and 48 in two forms.
In shielded cabling system, shielded twisted pair patch panel should be selected to ensure the integrity of the shield system.
