When it comes to network cabling, when it comes to network cabinets, everyone is familiar. Today, let's learn together what exactly is the patch panel, what is the jumper, what is the cable manager, and what they are used for. The so-called jumper frame is composed of flame-retardant modular plastic parts, which are equipped with a number of toothed strips for end-wiring pairs. The 788J1 special tools can be used to “punch” the wire pairs in sequence to the jumper frame. The voice trunk cable and the voice horizontal cable are terminated. Common specifications are: 100 pairs, 200 pairs, and 400 pairs.
 
Why use a telephone jumper?
 
Generally used in the computer room with a program-controlled phone. After the telephone line is connected to the program control machine, it is the line of the extension number that is received from the program control machine. Then snap all of these lines onto the jumper, then take the line from the outlet to your extension number, and place the number on the patch panel. There is a problem with the phone. Look at the label on the patch panel when you are overhauling, and then find the line along the line. It's easy. Don't use a jumper to make you die. The lines are the same as the chaotic group.
 
The role of the jumper
 
1. It can reduce the loss of network device interfaces such as switches.
 
For example, network administrators often plug and unplug lines and test lines. This will cause the switch results to loosen for a long time. If the connection is not tight, you need to use a jumper to use the cable from the work area. Installed on the jumper, and then make a small network cable - commonly known as jumper, connect the jumper to the switch, so that network administrators only need to unplug the RJ-45 at the end of the jumper. The interface is here. The jumper is much cheaper than the interface card on the switch.
 
2. Regular, neat, beautiful, professional wiring
 
Appearance, the jumper looks like a row of fish bones, also known as the fish skeleton. Usually used by telephone connection. The role of the jumper is to connect high-density voice data cables, providing convenient and fast termination wiring. The jumper can be used for both wall mount and vertical cabinets. The jumper has a wide range of functions and is suitable for high-speed applications in all voice communication systems, multimedia, etc.
 
The jumper frame generally cooperates with the 110 connection block to function as a jumper. There are many types of jumpers. Currently, there are 50 pairs and 100 pairs of legs and legs without legs. The connecting blocks are available in 4 pairs and 5 pairs. The role of the jumper is also related to the type of jumper. Different types of jumpers have different functions. Users should select the appropriate jumper when wiring.
 
Cable manager
 
The cable manager is an accessory that is installed in the cabinet and the distribution frame to allow the cable to enter the cabinet distribution frame more smoothly. Make the overall layout of the cabinet more beautiful and standardized.
 
The cable manager prevents the cable from turning at right angles before being pressed into the module, reducing the signal loss of the cable itself and reducing the radiation interference to the surrounding cable. Since the cable organizer allows the horizontal twisted pairs to enter the module regularly and in parallel, in the future, when the line is expanded, a large number of cables will not be changed due to the change of one cable, so that the overall reliability is ensured, that is, Improve the scalability of the system.
 
Patch panel
 
What is a patch panel?
 
A device used for end-user lines or trunks and capable of making a connection to them.
 
The patch panel is the most important component in the management subsystem and is the hub for the cross-connection of two subsystems, vertical trunk and horizontal cabling.
 
Patch panels are usually mounted in cabinets or walls.
 
By installing accessories, the patch panel can meet the needs of UTP, STP, coaxial cable, fiber optics, audio and video.
 
Patch panels commonly used in network engineering include twisted pair patch panels and fiber patch panels.
 
According to the location and use, it is divided into two categories: main distribution frame and intermediate distribution frame.
 
use
 
The location of the distribution frame is a modular device that manages the front-end information points at the central office.
 
The front-end information point cable (Super Category 5 or Category 6 cable) enters the equipment room and then enters the distribution frame. The line is placed on the module of the distribution frame, and then the patch panel and switch are connected by jumpers (RJ45 interface). .
 
In general, the patch panel is a device for management. For example, if there is no patch panel, the information point of the front end is directly connected to the switch, and if there is a problem in the cable, it is faced with rewiring.
 
In addition, the management is also confusing, and multiple plugging and unplugging may cause damage to the switch port.
 
The existence of the patch panel solves this problem, and the jumper can be replaced to achieve better management.
 
Usage and usage are primarily based on the number of overall network points or the number of network points on the floor (and adjacent floors, depending on how the system map is designed).
 
Different buildings, different system designs, and different distribution frames between main equipment. For example, if a building has only four floors and the main equipment is located on one floor, the network points of all floors enter the equipment room, then the number of distribution frames is equal to the number of all network points/distributor ports in the building (24). Mouth, 48, etc.), plus a certain margin; if a building has 9 floors and the main equipment is set at 4 floors, then in order to avoid excessive cable length, it is possible to have separate equipment rooms on each floor. And there are switching devices. Then the distribution frame between the main devices is equal to the number of network points on the 4th floor/the number of distribution frame ports (24 ports, 48 ​​ports, etc.).

What is the difference between the role of the patch panel and the jumper:
 
As the core product of the integrated wiring system, the patch panel plays the role of flexible transfer, flexible distribution and comprehensive management of transmission signals. It is a kind of norm, it is also neat, it doesn't look chaotic, and it can clearly know what it is. It is to make the changes of the line easier.
 
The jumper is a high-density voice data cable connection that provides convenient and fast termination wiring. The jumper can be used for both wall mount and vertical cabinets.
 
What is the difference between patch panels and patch panels?
 
Habitually you can understand two different things: the jumper is used to transmit voice signals; the patch panel is used to transmit network signals. But in reality, what is meant by the two depends on its predecessor. For example, ‘110 jumper racks’ and ‘110 patch panels’ all refer to the same thing; for example, ‘RJ45 patch panel’ and ‘distribution frame’ are generally considered to refer to network distribution frames.
 
Let’s talk about the jumper
 
It is customary to mention jumper racks, generally referred to as 110 jumper racks. Of course, some people call it 110 distribution frame, but no matter what it is called, it refers to the name of the 110 cross system. Generally used for the intersection of vertical and horizontal systems of speech signals.
 
In addition, it is also called: voice distribution frame, voice jumper, fish skeleton and so on. Generally divided into 50 pairs, 100 pairs, 300 pairs of models, need to use the connection block to use.
 
Let's talk about the distribution frame.
 
Mentioned that the patch panel generally refers to the RJ45 patch panel, or network patch panel, the current use of more than five and six categories. Generally used for the intersection of vertical and horizontal systems of network data signals. It is divided into two types: shielded and unshielded. There are two types of commonly used ones, 24 and 48. The shielded brands are divided into 16 and 32. But whether it is 110 patch panels or RJ45 network patch panels, they can be replaced with each other in purpose: 110 patch panels can transmit data signals, and RJ45 network patch panels can also transmit voice.
