What is a jumper frame?
Jumpers are composed of flame-retardant modular plastic parts, which are equipped with a number of tooth bars for terminal wiring pairs, the use of special tools can be the wire pair according to the line sequence "stamping" to the jumper rack, complete the voice trunk cable and voice horizontal cable termination, commonly used specifications are: 100 pairs, 200 pairs, 400 equals.
→ The role of the jumper:
1, Can reduce the loss of network equipment interfaces such as switches;
2. Orderly, neat, beautiful and professional when wiring.
Jumpers generally cooperate with 110 connecting blocks to play the role of jumpers. There are many types of jumpers, currently on the market to provide legs and legless 50 pairs and 100 pairs of two choices; You can choose between 4 and 5 pairs of connecting blocks. The role of the jumper is also related to the type of the jumper, different kinds of jumper have different roles, the user should choose the suitable jumper in the integrated wiring.
What is the distribution frame?
The distribution frame acts as the "nerve center of the network" for the end user line or trunk line, and can deploy the connected equipment to them. The distribution frame is the most important component in the management subsystem, and it is the hub to realize the cross-connection of the two subsystems of vertical trunk and horizontal wiring. The distribution frame is usually installed on a cabinet or wall.
Through the installation of accessories, the distribution frame can meet the needs of UTP, STP, coaxial cable, optical fiber, audio and video. The distribution frame commonly used in network engineering includes twisted pair distribution frame and optical fiber distribution frame. According to the different use place and use, it is divided into two categories: main distribution frame and middle distribution frame.
→ Role of distribution frame:
The positioning of the distribution frame is a modular device that manages the front-end information points at the office end. After entering the equipment room, the front-end information point cable (Class 5 or Class 6 cable) first enters the distribution frame, lays the line on the module of the distribution frame, and then connects the distribution frame to the switch with a jumper (RJ45 interface).
In general, the distribution frame is used to manage the equipment, for example, if there is no distribution frame, the front-end information point is directly connected to the switch, then if there is a problem with the cable, it is faced with rewiring. In addition, the management is chaotic, and multiple plugs and removals may cause damage to switch ports. The existence of the distribution frame solves this problem, and better management can be achieved by replacing the jumper.
What is the wire rack?
The cable manager is an accessory installed in the cabinet and used with the distribution frame. It enables the cables to enter the cabinet distribution frame parallel more smoothly. The cable tray simplifies the planning and installation of the cross-connect system. Simply put, it is to clarify the network cable, which has no direct relationship with the network, only for good management in the future, so that the overall cable of the cabinet is more beautiful and standardized.
→ The role of the cable rack:
The cable manager is used in the cabinet between the distribution frame and the switch. The network cable can be installed at the front end of the cabinet through the cable manager to provide horizontal cable management for the distribution or device jumpers, so that the cable does not make multiple right Angle turns before being pressed into the module, reducing the signal radiation loss of the cable and reducing the radiation interference to the surrounding cables.
Because the cable organizer makes the horizontal twisted pair enter the module regularly and in parallel, so in the future expansion of the line, it will not cause a large number of cable changes due to changing a cable, so that the overall reliability is guaranteed, that is, the scalability of the system is improved.
The contrast between the three
1. The difference between distribution frame and cable management frame
Distribution frame is used for integrated wiring, the network cable is driven into the distribution frame by the color of the cable connector, the cable management frame can be used to make your wiring in the cabinet more beautiful, the information socket is fixed on the wall, there are modules inside, and the network cable is driven into the module by color. Distribution frame, cable management frame is used to regulate the network wiring of a device, generally used in network installation (such as local area network, etc.), and the switch used, installed in the cabinet.
2.The difference between distribution frame and jumper frame
The jumper frame is used to transmit voice signals, and the distribution frame is used to transmit network signals. But in fact between the two in the end refers to which, but also depends on its front. For example, "110 jumper frame" and "110 distribution frame" all refer to the same thing; For example, "RJ45 distribution frame" and "distribution frame" are generally considered to refer to network distribution frames.
