In the last 5-6 years, the construction of China's data center is at a stage of rapid growth, and according to the forecast of Ami of the third party investigation organization, in the next 5 years or even longer period, the construction of domestic data center will continue to be in the fast growth channel, according to the report shows, Asia-Pacific Data Center Wiring Market Composite annual growth rate will reach 32.8%, China's composite annual growth rate is expected to reach 37.5%, than the
The past wiring method is to the various facilities of the wiring design and construction, such as telephone systems, fire, security alarm systems are independent. A high degree of automation in the building, a variety of line including, not only difficult to manage, cabling high cost, and lack of function, not adapt to the needs of the situation. Integrated wiring is to take these shortcomings and adopt standardized measures to achieve a unified mate
Bkjia.com November 23 Internet headlines]Our goal is to say goodbye to the intricate wiring.System Administrators usually do not admit this kind of thing, but in fact many people are really not very good at Cable layout, which is the main reason why I recently developed a universal solution for them. Recommended for editing: Open your eyes and take a look at the real standardized data center (multiple charts ))
Here I want to make a tough statement: System Administrators despise wiring. Most peo
Analysis of Optical Fiber Application Technology Based on Cabling Technology
1 key points of data center optical fiber design
(1) minimum allowable bending radius: In which case the installation of optical fiber is much easier than that of coaxial and UTP copper cables. The most important factor in cable installation is to keep the minimum bending radius of the cable. When the optical cable is smaller than the minimum allowable bending radius, the lo
The minimum bending radius must be monitored for Cabling Standards. If the minimum bending radius is not met, the cable may be damaged and its performance may decrease. For example, in a copper system, high return loss usually indicates that the bending radius is not properly controlled during cable cabling. In an optical fiber system, high attenuation may occur. These effects may only appear at one wavelen
The six-class cabling system provides a high-speed bandwidth of 2.5 times higher than that of the five categories, and a ACR value of 300% times higher than that of the five categories at MHz. In terms of construction and installation, Category 6 is much more difficult than Category 5.Construction personnel of cat6 cabling systems must comply with international standards. "The more advanced copper cables ar
As the infrastructure of Hospital Informatization Construction, network Integrated Wiring must be highly valued for standardized construction and high-quality maintenance. In my work, I undertake the specific work of Hospital Information cabling. I have the following experiences:

for networking. Since personal decoration is generally promoted by decoration companies, the sales can be achieved relatively high, so there are generally more functional requirements for the family, the number of points of implementation is also more. At this time, there are also requirements for system reliability and scalability. Because wiring is not a big problem at this time, the home decoration market should try to adopt star and bus methods. The old house transformation market generally
There are more and more equipment in the home theater, and some are no longer simply composed of a large color TV and a set of high-definition audios. If you place all kinds of lines in one place at will, it will undoubtedly compromise the entire family environment and easily lead to unnecessary accidents due to bumps.
For users who are preparing for decoration, which ones should be preinstalled for cabling and which ones can be laid out? In an interv
There are still many things worth learning about data center wiring. Here we mainly introduce the layout of power cords and network cables, including some valuable experiences in data center wiring, I hope this will help you, especially Internet cafe managers.
In the construction of Computer Room wiring, the layout of power cords and network cables is very important. These two types of cables are well laid out in the IDC room wiring. The computer runs normally, the failure rate is low, and teach
is already the E era, information sharing has become a means of efficiency, it must be accurate and rapid transmission between departments. For this reason, companies, businesses and government departments are pressing for improvements to these communications systems in the shortest possible time, and to configure a variety of wiring systems as needed. In China, even in the newly designed buildings, often still use the past wiring technology, resulting in a variety of systems
, when the clock frequency exceeds 100 MHz or the rising edge is less than 1 ns, the signal integrity effect becomes important.
In PCB, the signal line is the main carrier for signal transmission. The cabling of the signal line directly determines the superior signal transmission, thus directly affecting the performance of the entire embedded system. Unreasonable wiring will seriously lead to various signal integrity problems, and generate timing, noi
form a vertical channel of 178mm, which runs through the 45U height of the entire cabinet. The vertical wiring system allows cabling to be performed within the exclusive space of the server cabinet, providing additional installation space for the device. In a high-density network cabinet, you can set a cable slot channel to provide additional management space for the layout of jumper cables.

When strong electricity is used to go up the line, weak use of the next line, because it can make strong wire and cable security is guaranteed, at the same time the height of the computer room is not high, but also able to take into account the current situation of weak cable often need to adjust, but also
Our goal is to say goodbye to the intricate wiring. It's something that system administrators don't usually admit, but actually a lot of people are really not very good at cabling, which is the main reason I've developed a plan for them recently.
Here I have to make a difficult statement: System administrators despise wiring. Most people in the industry see this kind of menial jobs very low and think it is not worth wasting their valuable time. Wirin
-called integrated wiring system refers to a standard, unified and simple structured way to prepare and layout of buildings (or buildings) of various systems of communication lines, including networks, telephones, monitoring, power supply and lighting systems. Therefore, the integrated wiring system is a standard universal information transmission system. More precisely, integrated wiring is a modular, highly flexible information transmission channel between buildings or building blocks. (Comput

Formula for propagation delay of cabling in PCB
The first half is information from altera.
The propagation latency (tPD) is the time required to transmit a signal from one point to another. Transmission Line propagation delay is a function of the relative dielectric constant of materials.
Propagation delay of micro-Strip Layout
You can use formula 5 to calculate the propagation delay of the strip layout.
Formula 5:
Delayed propagation in the line
