Now that the network is so developed, it can be said that the distribution frame is one of the "heroes". Do you know what a distribution frame is? In addition, distribution frames can also be divided into several types. Let's give you a popular science about its principle and types ~

Distribution frame with a set of Ethernet or other ports on the front and bare wires on the back. Each port is mapped to the back of punched bare wires, and on the front panel, each port is marked with a number for identification purposes.
Usually, the patch panel is used as a centralized connection point for cables, allowing engineers to jump cables to quickly connect equipment. When your equipment needs frequent switching, the patch panel will make your work extremely easy.
In engineering practice, there are many types of distribution frames, such as telephone distribution frame, optical fiber distribution frame and Ethernet distribution frame.
For example, telephone distribution frame, today, fixed telephone is no longer common, except for some specific occasions. However, when fixed telephone becomes mainstream, telephone distribution frame is very common. In the fixed telephone network, the trunk cable is deployed from the core computer room of the service provider to the cell, and then the fixed telephones of the whole cell are separated from this connection point. This connection point is deployed as a telephone distribution frame. Each telephone line is pressed into the corresponding number with a hole punch.
