and 5 compared to the price increase is small, and the performance index is much better, so the phenomenon of Super 5 class is dominant. For now, compared with 6 categories, the price of 6 types of products needs to be 40% higher. But as time goes on, the above points will change, and progressively more than 5 classes will lead to the 6 categories. Especially high-end writing office building Yu Certainly, the residential area may be slightly later. The demand for high-speed transmission of da

hardware in the device room. It connects various devices in the public system. This subsystem connects the trunk line and the wiring intersection with public system devices such as PBX. Building Group subsystem: Implements interconnection between buildings. Commonly used communication media is optical cables or logarithm. optical cables or logarithm are used between the main line and the building group.

dynamic cable reduces the performance of the data cable, especially the speed of data transmission. Placing a steel Separator in a metal tray can greatly reduce the necessary distance between the dynamic cable and the data cable installation. As long as the separator board does not break continuously and has good electrical continuity, even if the dynamic cable and data cable are unshielded, the required interval can be reduced to 50mm. Third-party tests show that the increase of installation s

What are the skills for cabling? In the process of implementing the integrated wiring project, there are some skills to place the cables. Otherwise, the front and foot will have to be repaired if the cables are laid better. To this end, the manufacturer shared the following six main points about cable placement: First, suspension cables in the air: first, we must consider cable sag and pressure. After the test, determine the bundling method use

filtering.3. Information Server InstallationThe main task of the Internet network center is to provide Internet Information Services. The system includes the following information service functions: DNS, E-mail, WEB and FTP, Proxy service, News Service, bbs e-advertising board system, etc. The most common services are DNS, email, and WWW.4. browser InstallationThe browser uses the Navigator of Netscape.Integrated WiringThe structured cabling system i

The maintenance work required for the integrated cabling system in the integrated information machine room can be divided into the following four categories: daily management, daily maintenance, troubleshooting, and layout rectification. 1. Daily Management The daily management of the integrated wiring system refers to the adjustment of the position of the Integrated Wiring jumper and the change of the label. This part of work is simple and has almost

The demand for the soft route of sea spider in the soft route market is still very high, and its performance is also very good, maybe many people do not know how to use the soft route of sea spider through the vpn line, it does not matter, after reading this article, you must have gained a lot. I hope this article will teach you more things. I believe many of my eldest brothers have already learned and done well by Using VPN connections. Here, my younger brother is still here to popularize this

Title DescriptionDescriptionSchools need to connect n computers, and the cost of connection between the different 2 computers may be different. To save money, we consider the end of indirect data transfer, where one computer can indirectly connect to another computer via another computer.In order for any two computers to be connected (whether directly or indirectly), you need to use a network cable between several computers directly connected, now want to make the total cost of connection is the

entire Green Oil, however, we draw a square or a dot on the toppaset layer at the position of the wire. The square on the plate made out has no green oil, but copper and platinum. Because the PCB is green by default, a "Skylight" will be opened in the place where the two layers are laid, rather than green. It can be used in some places where large current flow is needed to facilitate addition of Solder Topsolder top-layer Solder Mask Bottomsolder underlying Solder Mask -- The full name of the

example, the four functional components are set, which are: Take the pointer, decode, analyze, and execute, allows overlapping execution of commands. If commands are not as regular as CISC, the pipeline will be less efficient. Hard wiring:It is fast to set commands in circuit mode, but it is difficult to modify Microprogram:Commands are placed in the control memory, which is slower than hard wiring, but it is easy to modify and add new commands. CISC will cause more and more complicated comma

Step 1: The break test is the basis The pass test is the basis for testing, and is a basic test of line construction. While only testing the cable for the break and cable line method is correct, but this step can not be less. You can use the expert tester for testing. Usually this is a general cable detection tool for wiring builders. Step 2: Authentication test most critical when cabling is completed, all cable systems need to be certified for

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
