What are Patch Panels?

A device used for end-user lines or trunks and capable of provisioning and connecting them. The distribution frame is the most important component of the management subsystem, and it is the hub that realizes the cross-connection of the two subsystems, vertical trunk and horizontal wiring. The patch panel is usually mounted on a cabinet or wall. By installing accessories, the distribution frame can fully meet the needs of UTP, STP, coaxial cable, optical fiber, audio and video. Commonly used patch panels in network engineering are twisted-pair patch panels and fiber-optic patch panels. According to different places and uses, it is divided into two categories: main distribution frame and intermediate distribution frame.

A device used for end-user lines or trunks and capable of provisioning and connecting them. Distribution frame is

The main distribution frame is referred to as MDF, which is used to connect subscriber lines, trunk lines, and dedicated lines to the corresponding interface points of telephone exchanges for testing, wiring, and protecting equipment in the office.

The structure of the MDF is divided into two sides, in-line and in-line. For in-line trunks or dedicated lines that do not need protection, test bars or terminal strips can also be installed. The same type of main distribution frame can be spliced to meet the needs of expansion. The main distribution frame of the subscriber switch is usually of the box type due to its small capacity. Early total distribution frames were large, with a maximum capacity of 303 lines per in-line. The security guard uses a 20 or 21 wire carbon lightning arrester and uses a thermal coil to limit the current. The test row is 20 wires, and the four-wire shrapnel type is used. Separating the shrapnel can separate the incoming line and the outgoing line. In order to cooperate with the program-controlled switchboard, the new main distribution frame vigorously reduces the volume and weight, and each column can hold 1,000 lines. Make sure to arrange 100 lines per block, and use metal discharge tubes to prevent high voltage and overcurrent. Each test line has 128 wires, which can be separated to contact the reeds, and the wires can be easily separated for testing. The wires connected to the terminals have independent wiring troughs, which is convenient for installation and maintenance. Make sure to use the card connection method to connect, and do not need to strip the insulation layer of the wire when the card is connected. The test bar is connected by winding. Both wiring methods are simple, reliable, fast, and pollution-free. According to different occasions, the new distribution frame is available in wall-mounted, floor-mounted, single-sided and double-sided types.

The main functions of the main distribution frame are: security. Protect the user line against high voltage or high current; wiring. Any user can choose the number in the office, the trunk between different offices can choose the trunk module in the office, and can connect the office and related subscriber lines according to the needs of the dedicated line.

The intermediate distribution frame is referred to as IDF, which is a distribution frame that connects the incoming and outgoing lines between the internal telephone exchanges. According to its installation location, it can be divided into two types: the main distribution frame and the intermediate distribution frame of the switching equipment and the inter-machine distribution frame.

The structure of the IDF is also divided into two sides, in-line and in-line. The in-line connects the outgoing lines of the equipment, and the in-line connects the incoming lines of the equipment. Both in-line and horizontal rows are equipped with terminal blocks. The improved terminal strip is wound on one side. The other side is the bonding wire. The function of the IDF is to allocate the access lines between the switching equipment at all levels in order to give full play to the role of the switching equipment at all levels.
