Development and Application of Integrated Wiring System

The Integrated Wiring System is still commonly used. So I studied the development and application of the Integrated Wiring System. Here I will share it with you, hoping to help you understand the Integrated Wiring System.

As the core product of the Integrated Wiring System, the distribution frame plays a role in flexible transfer, flexible distribution, and integrated and unified management of transmission signals, the biggest feature of the Integrated Wiring System is to transmit different information on the same interface and the same transmission medium, the implementation of this feature is mainly achieved by connecting the patch frames with different information. the following describes several common distribution frames and their reasonable matching in practical application.
At the end of 1980s, the Integrated Wiring System had just entered China. At that time, the information transmission rate was very low, and there were only three types of cabling systems (16 MHz). The wiring system mainly used 110 fish bone frame distribution frames, which were mainly divided into 50 pairs, 100 pairs, 300 pairs, 900 pairs of wall mounted types, and from the main distribution frame between the main equipment to the distribution frame between each distribution line, no matter the connection trunk or horizontal cable, all use this distribution frame. the advantage of the 110 fish bone distribution frame is its small size, high density, and low price. It is mainly used together with the 25/50/100 pairs of large logarithm cables. Its disadvantage is that it is troublesome to connect the cables, one-time terminal connection should not be changed. There is no shielding product, and the terminal connection tool is expensive, which is inconvenient for maintenance and management upgrade.

As the network transmission rate increases, the cabling system has five (100 MHz) products, and network interfaces are gradually unified to RJ45, the distribution frame for end-to-end transmission data cables adopts a 19 inch RJ45 port 110 distribution frame. The back of the distribution frame adopts a 110-end connection mode, and the front is all RJ45 ports for jumper wiring. It is mainly divided into 24 ports, 36 ports, 48 ports, and 96 ports, all of which are 19 inch rack/Cabinet-type installation. Their advantages are small size, high density, simple end-to-end connection, and repeated end-to-end connection.

It is mainly used for the end connection of 4 pairs of twisted pair wires and provides shielding products. Its disadvantage is that the incoming cable is connected to the back of the distribution frame, and the management of the Jumper is completed on the front of the distribution frame, therefore, maintenance and management are troublesome. Because the ports are relatively fixed, no matter how many desktop information ports you want to manage, you must configure them in multiples of ports 24 and 36, as a result, the distribution ports are vacant and wasted, and they are not flexible. In addition, the price is relatively higher than that of the 110 fish bone frame.

Today's rapid development of network technology and transmission rate, the emergence of gigabit/10 Gigabit Ethernet technology, the launch of cat5e (100 MHz) and cat6 (250 MHz) cabling systems, in addition, users require a variety of network system applications, such as Intranet (shielded), Internet (unshielded), voice, and optical fiber to desktop. In the face of flexible management of multi-functional information ports, it puts forward higher requirements on the diversified, flexible, scalable and other performance of the wiring system, such as the multimedia distribution frame launched by some wiring manufacturers such as Schneider Electric, it meets the requirements of modern network communication applications for wiring systems. This distribution frame abandons the weakness that the fixed RJ45 port type 110 distribution frame port cannot be changed in the past. It is an empty distribution board with a standard width of 19 inch and a 1U High.
You can configure cat5e, cat5e, cat5e, voice, optical fiber, and shielded/unshielded wiring products, A 1U high can be configured with up to 24 copper cables or optical fiber ports and 48 voice ports, which fully reflects the diversity and flexibility of the wiring and brings great convenience to the upgrade and expansion, because of its independent modular configuration, each port on the distribution frame corresponds to the information port on the desktop one by one. Therefore, when configuring the distribution frame, you do not need to configure the port multiples of 24 or 36, this will not result in the vacancy or waste of wiring ports. In addition, the installation, maintenance, and management of such distribution racks are all performed on the front, it greatly simplifies the operation process and allows you to configure a shielding and unblocking system on the same distribution board at the same time, which is another characteristic of the old distribution frame.
At present, voice communication is also undergoing great changes. Generally, the well-known analog telephone system is gradually being replaced by new digital communication systems, such as the latest VoIP technology, in addition, the popularity of some four-core phones has also changed the voice wiring system. Some wiring manufacturers headed by Schneider Electric have successively launched the IDC Voice Distribution Frame with RJ45 ports. The back of the Rack adopts the IDC mode to connect multiple voice pairs.
In view of the biggest feature of the Integrated Wiring System, the same interface and the same transmission medium are used to transmit different information on the Integrated Wiring System, to flexibly control the application functions of each desktop information point. Therefore, the RJ45 port 110 distribution frame should be used to end the distribution frame from all desktop information points with horizontal twisted pair wires, it is used to connect the multi-logarithm voice cables from the telephone master data center with a 110-bit fish bone distribution frame corresponding to the corresponding logarithm. The patch cord is used to connect to the RJ45 110 distribution frame for voice communication, the data fiber trunk uses a fiber distribution box and a network switch to convert a high-speed optical signal to a multi-channel data signal. The standard RJ45 patch cord and the RJ45 port 110 distribution frame jumper are used to achieve desktop information point connection.
