Introduction to computer network structured Integrated Wiring System
StructuredCablingSystem (SCS) is a module system based on star topology developed by Bell laboratory experts for many years. It is also the preferred system for LAN construction. The system has the advantages of practicality, flexibility, economy, modularization and scalability. It can connect data communication equipment with other information management systems and connect these devices to external communication networks.

This article mainly introduces the importance of the integrated wiring system management, the development of wiring management technology, the standard of wiring management, the management of racks and cables, and the intelligent application of wiring management.
1. Scope of cabling Management
Cabling management is the wiring device for the working area between devices, cables, information outlets and oth
Integrated wiring system in China has more than 10 years of history, wiring engineering after 10 years of development has become increasingly mature, the performance of transmission media has been increasing, wiring scale is also more and more large, but cabling system management is often overlooked. We know that the flexibility of the integrated wiring allows users to increase or decrease or jump in the system maintenance, change the network connecti
Project OverviewThe dam area of the world-famous Three Gorges project is located in sandouping, Yichang City, Hubei Province, and the Three Gorges Project construction management center is located in the 15th work area of the dam area. In order to effectively manage the progress and quality of the Three Gorges Project, coordinate the relationship between construction units, establish a strong communication and computer network system, and collect and process a large amount of information. Commun
After reviewing the network development process, we will all feel that the network is evolving with each passing day, and network applications have been updated and upgraded almost every several years, the continuous development of network applications puts forward higher bandwidth and other related performance requirements to people. With the popularization and application of gigabit and 10-Gigabit networks, in our traditional cabling system, current
intensive short-range applications, such as fiber-to-home and fiber-to-desktop, the connection is difficult, expensive, and expensive for installation and maintenance.
At the same time, with the continuous development of the computer network transmission rate in the office environment, the high data rate to desktop applications become more and more common, and the LAN speed is also changed from 10 Mbps to 100 Mbps, and will soon grow to Mbps. for cabling

So how to master the quality of these media to ensure smooth transmission of information, you need to rely on the verification of the Cable Testing Instrument. In addition, more than 90% of the network faults are caused by cable link problems, but these problems can not be checked in the shortest time only by visual or multimeter. During network construction, you must test the cable using a regular tester.
In general, the network card will not strike easily, most of which are network faults caus
Data CenterIn general, administrators will first apologize for messy cabling. Wiring is simple-connecting servers to network switches with cables. However, cable placement like "noodles" affects the cabinet space utilization and appearance. chaotic scenes are like the tangle of many snakes, which cannot be clarified. We understand how things have evolved so far, but we cannot determine the root cause of this result. Is such chaos the result of technol

Impact on the Performance of Electronic Devices
Structured Cabling System inlet may have a major impact on the ability of cables to support high-speed data applications (such as fast Ethernet and Gigabit Ethernet. In some cases, cables that are close to the maximum link length specified by the standa
First, the preface
Cisco reports that global networking equipment is expected to increase from 5 billion units to 15 billion by 2015, and 2015 Global monthly Internet traffic will increase from 1 bytes in 2004 to 80 bytes (1 MB = 1 billion GB).
In the face of such a huge internet equipment and data flow, it is bound to have a corresponding number of basic wiring system to support, especially in the relatively centralized data flow of the Internet, finance and telecommunications industries, the
Differences between indoor and outdoor Network cables and Network Cabling Process
Differences between indoor and outdoor Network cables
As the name suggests, an outdoor network cable is a cable used outdoors. An indoor network cable is mainly used in an indoor network cable.
The biggest difference between an outdoor network line and an indoor network line is that the outdoor network line has two layers of external lines, but the indoor network line h
not exceed 1 inch, which is much smaller than the multi-pipe structure used in the air-blown Optical Fiber System. After the optical cable is dragged, the optical fiber is laid and the hardware device is connected. The link loss can be determined and the optical fiber can be put into use. The material cost of this system is lower than that of the air-blown optical fiber system because hardware is not required in other places except at both ends of the optical cable. The design is fixed and can
1. category 6 Cabling systems should be selected from the overall transmission medium, because category 6 is a permanent link-level cabling system. In addition to selecting excellent performance cables, connectors are also important, for example, cat6 information modules, cat6 distribution frames, and finished cat6 UTP jumper cables.
2. the compatibility and matching of the products are also very important.
transmission media, the twisted pair is at the transmission distance, channel width and data transmission speed are limited, but the price is relatively low. Twisted pair cables (referred to as twisted pair cables) are the most common transmission medium in the Integrated Wiring System. In the star network topology, twisted pair cables are essential for cabling. Twisted Pair wires can be divided into two categories: unshielded twisted pair UTP and sh
There are many things worth learning about Integrated Wiring. Here we will mainly introduce the six precautions for Integrated Wiring, including the design, construction, and acceptance issues, hope to help you. This year, the TIA/EIA committee officially released the Generic Cabling Standard 6: ANSI/TIA/EIA-568-B.2-1), TIA568B has truly become a network that can fully meet the current situation of development, the basic standard set for network const
There are many areas worth learning about integrated cabling planning for data centers. Here we mainly introduce the network division of Integrated cabling planning for data centers, this includes information on the internal office network of the data center management company and the demonstration and testing network of the management company. We hope to help you.
In the past few years, the development of
Along with the rapid development of society, various industries, departments and home users of the information needs more and more, the development of computer communication network technology for the realization of large capacity, rapid delivery provides the possibility, so more and more units and home users began to consider how to effectively layout, install network communication lines, So that in the future can easily connect to the local area network or the Internet, so as to achieve high-s
the wiring system can open a certain or several applications, such as telephone can call, or hundred Gigabit Ethernet can run, it means that the wiring system passed through, the key is not to go through the field test tester. The reason is that wiring system can not be used alone, is in order to run some application protocols in the wiring system, of course, to open the test of the subject, the light to measure a pile of data what is the significance? This approach seems reasonable, and it is
Integrated wiring management is for equipment, switching between the work area of the wiring equipment, cables, information outlets and other facilities, according to a certain pattern of identification and records, including: management, identification, color standard, cross connection, jumper, such as the implementation of such content to the user system maintenance, management to create convenience, improve the management level and efficiency , thus realizing the flexibility, openness and exp
