How many types of network distribution frames are there? Summarize several types of network distribution frames currently on the market.
Modular distribution frame
The modular distribution frame is the most common and most used distribution frame. The front panel of the distribution frame is an RJ45 interface, and each interface is marked with a number for easy identification; the rear panel is a wiring module, and T568A is displayed According to the T568B wire sequence standard, we need to use wire pliers to punch up the network cables according to the wire sequence.
Snap-in distribution frame
Card-connected distribution frames are currently used in many projects, and there are two sizes of 1U (24 ports) and 2U (48 ports). This kind of distribution frame has been installed with snap-in modules at the factory, so the front and rear panels are all RJ45 interfaces, and there are also digital marks on the front panel to facilitate identification of each port. The card-connected distribution frame is much faster and more convenient to use than the modular distribution frame. It is enough to directly make the network cable into a crystal head and plug it in. It is very suitable for high-density wiring applications.
Electronic distribution frame
Due to the relatively high cost of the electronic distribution frame, it is rarely used in the project at present. The electronic distribution frame can analyze and form data through detection lines, which brings convenience to network maintenance personnel and quickly solves network line problems. The wiring method of the patch panel is the same as that of the snap-in patch panel, just plug in the crystal head directly. There are two types of detection for electronic distribution frames: port detection and link detection. The network jumpers used in different monitoring methods are different, and the specific decision is based on the equipment manufacturer.
