traffic. GE Ethernet can satisfy the "greedy" appetite of network users for large bandwidth applications, which is undoubtedly the next major development direction of the network. When selecting the cable type, designers of Gigabit Ethernet have considered a large number of existing Cat5 applications. Therefore, the physical bandwidth is 100 MHz. In this way, in principle, Class 5 lines can run Gigabit Ethernet. However, the actual statistical result

.) indicates the number of revisions to the specification, and the actual number of twists in the network cable (or the connection quality of the socket. CAT1 is usually used in telephone lines. This type of line does not support computer network traffic and cannot be twisted. It is also used in telephone companies to support ISDN. CAT1 network cable is used in customer websites and telephone company networks. CAT2, CAT3, CAT4,

/Category 5 lines, regardless of their appearance, in terms of touch, there are obvious differences. Fake goods are usually the result of some manufacturers re-packaging the original four or even three categories of lines, which is less than 5 categories/more than 5 linear capabilities, however, it is difficult for general users to identify which seller sells the true amp cable. Based on the author's purchasing experience, I have accumulated the following experience in purchasing the ampo line:F

With the development of science and technology, the price of computer is getting lower, the performance is getting better, the transmission speed of LAN is more and more fast, and the transmission medium of LAN has shifted from coaxial cable to twisted pair and optical fiber, twisted-pair line from the initial CAT1, CAT3, CAT5 to the present CAT5e, CAT6 CAT7. Although the performance of twisted pair has be

wiring Application Analysis In view of current network application, it is very important to design the topological structure of twisted cable for digital output correctly. From the standard cabling Network application diagram, we can clearly see the relationship between transmission medium and network equipment and node equipment. For example, terminal equipment all choose 10MBIT/S Network card as an excuse, then the whole wiring all use CAT3 twiste

not lose low-frequency information or DC information. The common-mode level at the output end of the differential mode can be adjusted by the input voltage of the VOCM pin, in this way, the input level can be quickly translated when A/D converter of A single power supply is driven. The rapid overload recovery capability of AD8132 ensures its sampling accuracy. AD8132 can also be used as a differential mode signal driver to transmit high-speed signals through a cable or coaxial cable. AD8132 can

With the development of science and technology, the computer price is getting lower and lower, the performance is getting better and better, the transmission speed of LAN is getting faster and faster, and the transmission medium of LAN is also switched from coaxial cable to twisted pair wires and optical fiber, twisted Pair wires have evolved from CAT1, CAT3, and CAT5 to CAT5E, CAT6, CAT6A, and CAT7. Althou

double stranded line per meter is only about 1.5 yuan. is so popular, so its fakes are the most, some to almost the real, it is difficult to distinguish between true and false. According to the author's procurement experience, in the AMP line purchase has accumulated the following experience: First from the network cable identification, three types of line identification is "CAT3", bandwidth 10M, applicable to 10 trillion nets, the current basic has

At present, the most common fake network cable in the market is up to three categories of four counterfeit five categories and super five lines; or fake brand names with miscellaneous brands. So, how to distinguish between true and false? Wiring expert black and white Bear has written to warn users that you can distinguish between true and false by the following methods. The is first identified from the network cable identification. The three-class line identification is "

material, only a layer of insulating rubber package, the price is relatively cheap a lot, but also can make their own, the advantages are no shielding housings, light weight, easy to bend, good flame-retardant effect. In addition to the electromagnetic radiation severity, high transmission quality requirements such as the use of STP in the wiring, in general, we are using UTP. UTP Twisted pair is also graded, the existing UTP can be divided into three categories, four categories, five categori

cable is considered genuine (Note: it cannot be completely guaranteed :)). Then determine the type of the twisted pair. The wires in the twisted pair cables are paired, and each two wires is a pair and twisted. According to the U. S. Cable specification (AWG): All wires in twisted pair wires should be 4 pairs, a total of 8. However, the 10 M Ethernet standard requires only two pairs of wire transmission signals, so some of the three types of twisted pair wires are two pairs, while some are four

Therefore, the Protocol is essentially an agreement, and it is a formal agreement. For example, IP is the layer-3 protocol of OSI/RM. The standard has a wider scope. It includes not only written conventions, but also all uniformly executed rules on the network. Therefore, standards are sometimes referred to as norms or rules. For example, IEEE 802.3u is a fast Ethernet

transmission speed of 1000 Mbps) in the future, 5 category twisted pair wires with a transmission speed of Mbps are also in use. Although Fast Ethernet only uses 2 pairs, all 4 pairs must be used for Gigabit Ethernet. We recommend that you check the online tags. For example, the tags marked with "CAT3" are generally three types of cables. When the tags marked with "CAT5" are five category twisted pair wire
