Overall Design of network cabling On the basis of fully understanding of network requirements, we should make scientific ideas and ideas about network cabling, and position the overall design of the integrated bus cabling system engineering. The overall design is the most important basis for Engineering Construction. Only after a reasonable overall design of the

6 Type of data cabling is not large and medium-sized cities Office, commercial class building wiring system of the mainstream technology? In our country's data wiring market, 6 kinds of products launch only a few years, "6 kinds of wiring system is the mainstream technology" in the industry have heard. By June 17, 2002, ANSI Tia/eia formally passed the 6 wiring standards, and in June 24 as the appendix of TIA/EIA-568B officially published, named 568b.

In multimedia, a variety of audio and video technology is widely used today, users of the network requirements are more and more high, the amount of data transmission has become more and more big. In this environment, as the bearer of data transmission-transmission media become more important, when the network construction enterprises, network cabling needs to build a strong performance and safe and effective foundation. Therefore, in the network

In view of the current domestic structure of integrated wiring in the field of staff quality is uneven, the test methods and testing standards of the understanding of the deviation, this newspaper will be in the wiring system testing of the parameters involved in the test and the principle of some brief introduction, in order to stimulate the domestic industry elite to express ideas, Jointly promote the development of wiring industry.If the new test standard of class five and six can be launched

The integrated wiring system is the transmission network in the building or the architectural complex, it is the Line foundation of the computer network. It connects voice to data communication devices, switching devices, and other information management systems, and also connects these devices to external communication networks. Following, on the integrated wiring selection principle, market (brand, manufacturer, positioning) angle and engineering application angle three aspects to discuss: Ge

This article will discuss, is not a specific case of fiber cabling, but the wiring of some of the points of attention to make a hint, in order to have the interest of friends for reference. First of all, we should understand the optical fiber communication. Fiber is the abbreviation of optical fibre, consisting of fine glass filaments about 0.1mm in diameter. It is transparent and slender, although it is thinner than hair, it has a guided wave structu

as national standards organizations, have successively issued engineering design and management specifications for integrated wiring systems. EIA/TIA-606 is a milestone, which first proposed the identification, marking and recording of wiring elements. The birth of the electronic distribution frame system does not mean to get rid of these requirements. The core of the Integrated Wiring System is the cable. It must fulfill its basic mission: to connect the cable. So what is the major stride of t

Almost all projects require performance verification tests on the cabling system after construction. At present, copper cable testing methods, instruments and testing standards have been widely used by practitioners. Compared with copper systems, the popularity of optical fiber testing is much lower. Many projects do not perform fiber link tests, or only use a VFL light source to verify the optical connection. Using VFL light source to test the connec

The structured Integrated Wiring System provides users with the most reasonable cabling mode, and relies on its high-quality materials to change the traditional wiring, it laid the foundation for a modern building to truly become a smart building without changing communication lines within 15 years.A structured cabling system consists of six subsystems and is defined separately:I user subsystem: A User subs

, mainly how to minimize signal attenuation. Emphasis on optical fiber selection The selection of Optical Fiber not only depends on the number of Optical Fiber cores and the type of optical fiber, but also depends on the use environment of the optical fiber. For example: 1. If the transmission distance is less than 2km, you can select multi-mode optical fiber. If the transmission distance is over 2km, you can use a relay or single-mode optical fiber. 2. Pay attention to the flame retardant, toxi

Cabling is an important part of home network construction and is closely related to the use of home gateways. There are many areas to pay attention to in home wiring, such as weak current, such as network cables) and strong power supply lines. The distance, direction, and position of the lines should be referred to the relevant national standards, use pv c pipe and other pipes to protect the network cable as much as possible, and use the rounded corn

, so the modular data distribution rack between devices should provide not less than 300 RJ-45 interface. If the modular data distribution frame with 24 interface is used, the number of wiring racks required between the devices should be 13 (300/24=12.5, the rounding up should be 13).It is known that one floor of a building using optical fiber to the desktop cabling scheme, the floor of a total of 40 optical fiber points, each fiber information points

PCB Cabling 6 Major principles1 power, ground processing not only in the entire PCB board in the wiring is done well, but due to the power, grounding the consideration of the interference caused by, will make the performance of the product decline, and sometimes even affect the success rate of the product. Therefore, the wiring of electricity, grounding wire to be taken seriously, the electricity, ground noise caused by the interference to a minimum t

The wiring industry is tightly regulated in terms of transmission performance and security. Cabling security is critical, and various standard entities and industry organizations around the world have developed comprehensive documentation for this purpose. Cabling safety one of the most recognized authorities is the American Insurance Business Laboratory (UL), a non-profit organization that is committed to

personnel. For the Intelligent Transformation Project, you can choose to add the intelligent wiring management component. When the original distribution frame is retained and the original interface location is maintained, the component is embedded outside the distribution frame, to turn the original passive common distribution frame into an intelligent distribution frame for management and operation, the CAMS software is also adopted. Intelligent Electronic wiring management system modules acco

to measure the Jumper wiring, except for the wiring diagram test, other test items have little significance. ■Testing Frequency of 155MHz Because ATM uses the NRZ encoding method to transmit digital signals, although its data transmission rate is 155 Mbps, the required bandwidth is only 67 MHz. Therefore, an ATM network can be run on a wiring system that has been tested at a frequency of MHz used by a five-category cabling system. Many users mistaken
