I. Introduction to the brand recommendation of Super Category 6 network cable
The types of twisted-pair cables are generally divided into eight categories: 1 cables are mainly used for voice transmission; Class 2 line is mainly used in the old token network, because its transmission frequency is only 1MHZ. Class 3 lines are mainly used in 10BASE-T networks; Class 4 line token network and10base-t/100base-t network; Category 5 cables have a transmission rate of 100MHz and are used in 100BASE-T and 100 base-t networks. This is the most commonly used Ethernet cable. Category 5 cables are mainly used for Gigabit Ethernet (1000 Mbps); The transmission frequency of Class 6 lines is 1 MHz ~ 250 MHz, which is suitable for networks with transmission rates higher than 1Gbps. Category 7 cable is the latest unshielded twisted pair with a transmission frequency of at least 500MHz and a transmission rate of 10Gbps. In short, it is to classify network cables. The higher the category, the better the transmission performance, and of course the more expensive it is.
Difference between Category 6 and Category 6 network cables: Most Category 6 network cables use the same modules and jumpers as Category 6 network cables of the same brand, so their main difference lies in cables. IBDN's super-Category 6 cable 4800LX is set to run normally at high temperature from the beginning, so one of its cable construction features is large wire diameter, and the diameter of transmission conductor is increased from 0.5mm(24AWG) to 0.6mm(23AWG) of ordinary Category 6. Some manufacturers used 24AWG in the original super-6 cable and tried to improve the next method, but in 2002, the diameter of the improved cable was increased to 23AWG.

2. What are shopping tips?
First, what kind of network cable material is good, the following is a brief explanation: pure copper: this kind of network cable is the best, copper has the second smallest resistance under the same conditions, and can be made into high-quality wire. And the resistance is small, so that the loss of power in the transmission process can be avoided. 2. The quality of network cable such as aluminum cable is not as good as that of copper cable, but it is useless to use it for a short distance. Therefore, this kind of cable can be selected for switch lines, home or small office terminals. This kind of wire is only suitable for short-distance POE power supply because its resistance is larger than that of copper wire. 3. Copper-clad aluminum wire This kind of network wire is plated with a layer of copper outside the aluminum wire. Due to the skin effect, the conductivity of aluminum wire has been improved to some extent. But this kind of wire is only suitable for short-distance POE power supply, also because of the large resistance. 4. Mixed Conductors Some wires in this network cable use copper, while others use aluminum, which is only suitable for short-distance use and can be used for POE power supply. However, when making the crystal head, it must be made in strict accordance with the conductor sequence, otherwise the copper wire can not supply power, which will increase the resistance and affect the power supply effect.
Second, when purchasing, we should pay attention to distinguish different kinds of signs and quality: the sign of the third line is CAT3, the sign of the fifth line is CAT5, the sign of the super fifth line is CAT5E, and the sign of the sixth line is CAT6. 2. Touch by hand: High-quality network cables are generally made of copper wires, which are relatively soft. Inferior wires are hard, not easy to bend, and easy to break in use. 3, cut with a knife: remove the plastic skin to expose the core, the white core is white, and the fake is generally pure white or the color is not obvious. Good network cable with moderate winding density and counterclockwise direction. 4. Burning: When tested at a high temperature of 35℃ to 40℃, the rubber outside the genuine network cable will not soften. The rubber outside the real cable is flame retardant, and some fake ones are not flame retardant.
Third, in the long run, we need to consider buying more advanced network cable types, because it is often difficult to update and replace cables after installation. Basically, a wiring system should be based on at least 10 years, and can support the performance update of 4 to 5 generations of network equipment. If future network devices need better cables, the data speed can be improved. Then, it is inevitable to replace the super-category five cables with category six cables, but the renovation project of these cables is very expensive, so even if the price of category six products is slightly more expensive than that of category five products, in order to reduce the problem of network upgrade in the future, category six products are still worth considering.
Because the super 6 network cable is a common network cable product in the market, we should pay attention to the choice of brand and quality when choosing it. If there is a problem with the quality of the network cable, it will lead to slow network speed, dropped line and inability to access the network. In order to avoid problems after installation, you can use tools or feel to test the quality of the network cable when purchasing. I hope the above content is helpful to you.
