does not need to test the line outside Crosstalk Shielding system using metal shielding layer can completely eliminate line outside crosstalk (AXT), that is, the provision of high enough line outside Crosstalk (AXT) allowance, if the use of shielding 6 a (CAT.6A) wiring system, on-site construction does not need to test the line outside Crosstalk (AXT), only need to test the electrical parameters in the channel. Because of the complexity of the testing process, long testing time, and expensiv

network cables for network cabling. They are divided into two types: shielded and unshielded. If it is used outdoors, The Screen Shield is better. Generally, it is enough to use non-shielded five-category cables in the room. Because no Screen Shield is provided, the cables are relatively soft, but their connection methods are the same. In general, there are four pairs of lines twisted together in the cat5e

transfer experiments on 5 pairs of twisted-pair wires. The precursor bit Ethernet 1000base-t is being developed, and is based on 5 types of cables to transmit 1000Mbps of data. However, when the signal is transmitted at a high frequency on the line, if you do not take certain measures, will still be due to external electromagnetic interference and cable interna

phenomenon. As the pairing line is not used in 3 and 6, there is no problem in the case of short distance. However, once the distance gets longer, the fault will occur. You only need to repeat the RJ45 header in line order to restore everything to normal. In addition, several twisted pair cable manufacturers, in order to better meet the performance standards of

In general, there are four pairs of lines twisted together in the cat5e category and marked with different colors.

the average price of a bucket (305 meters) of brand goods, which is about 400 yuan, but that of fake goods is about 200 yuan. In this way, an additional 100% of the profits will be incurred when you buy fake goods. Now we have found out why fake goods are rampant in the market !! How can ordinary home users avoid these things when setting up a local area network? Next, we will introduce the three network accessories which should be paid attention to in terms of purchasing:Network

Experience and facts tell us that the advantages of UTP transmission video really enhances our use of twisted-pair video transmitter in the project confidence, but in the actual product purchase and wiring applications, or there will be some problems, to its summary, as follows: 1 in order to enhance the anti-interference ability, use the shielding line Some friends have long been using coaxial lines for

between Z + and Z-to ensure correct matching. The coaxial cable transmission video achieves the desired effect by means of Impedance Matching and unbalanced outer-end equipotential (shielding), while the twisted pair wire transmission video uses parasitic impedance differential offset to ensure frequency response, differential reception is used to suppress exter

The quality of twisted pair wires may affect the overall network performance during network construction. The connection of twisted pair wires between various devices is also very exquisite and should be connected according to specifications. This article mainly introduces the standard connection method of

expanded in the following order: red, green, blue, and Brown (this order is easy to remember: Red, green, and blue are very familiar to people; or, RGB is also a familiar concept, just add a brown color ). At the same time, ensure that the two-color cables are in front of each color network cable, and the monochrome network cable is behind (this rule does not need to be remembered: Double Single, single an

Many people (including the author) think that 10 Base-T 10 m networks use four of the eight signal lines in the network cable, the 100 Base-t m uses all eight signal lines (or how fast ?). However, when the author recently used a 10 m direct connection method (switching between 1 and 3, 2 and 6, and shielding the other four lines) to connect the network cable, unexpectedly, it was found that the Network was

product, the customer will naturally not pay great attention to the places that should be avoided, as a result, interference and lightning damage may occur. Imagine tens of thousands of volts of Thunder can split a big tree into several petals. What is a small pair of wire transmission equipment ?! The chassis will be melted by it. What role can anti-Detonator play. Therefore, in cabling, we must be realistic and avoid them as much as possible. In ad

So how to master the quality of these media to ensure unimpeded transmission of information, it is necessary to rely on cable testing equipment verification. In addition, in the cause of network failure, more than 90% of the fault is due to cable link problems, but these problems are not only visual or multimeter can be in the shortest possible time to check out. In the process of building the network, we m

During the construction and completion of the Integrated Wiring project, it is often necessary to check the quality of the wiring project. The construction quality of twisted pair wires bears the brunt. based on years of experience in design and construction, summarize a set of practical detection programs and describe them to share with your peers. Pre-test check is indispensable Inspection includes appear

Choose 1000BASE-T: Gigabit Ethernet implemented on the fifth type twisted pair?1000BASE-T (Gigabit Ethernet implemented on the fifth type twisted pair) is one of the best choices for network administrators for several reasons. It is mainly to meet the existing network in the rapid increase in bandwidth demand. In thes

voter who made the decision to support CFI. This milestone is also a good news for those who balance twisted pair copper cabling. This milestone will encourage more companies to invest more in research and develop faster and better technology on the medium they have adopted or preferred. In the new generation of BASE-T technology field for more research and investment, optimize the future of product select

The preferred LAN cabling system is the twisted pair cable system. Among them, the mainstream choice is a system with over 5 categories or higher performance. For cabling systems, the most basic test conducted by the installer is to use the connectivity tester to verify the end-to-end connection of the link. These testers provide complete wiring diagram tests, us
