Now we are using network cables for security systems, network systems, and even home networks. Obviously, as the demand for network cables increases, the frequency of network cables is increasing.
The use of home network expansion, network monitoring systems, POE power supply systems, and building intercom systems are mostly used for network cable routing.
What network cable should we use for the monitoring system? Let's discuss it together. First of all, its name comes from. The reason for the 5 types of network cable is that it has been experienced for 4 generations. It is true that there are 1 class 2 class 3 class 4 class, and then updated to 5 class, that is We use this much more. Interested, you can go over the equipment and technical parameters of the 1-4 twisted pair, which has been eliminated, not much to say here.
In fact, the name says that there are five categories, six categories and seven categories. From one to seven types of network cables, the larger the number, the newer the version, the higher the bandwidth, and the higher the price. In application, China has not used 7 categories. Here are some of the commonly used categories.
Five types of network cable: The transmission bandwidth is 100Mbps, and the outer surface of the network cable is marked with the "CAT5" logo.
Super five types of network cable: transmission bandwidth of 100-1000Mbps, the outer line of the network cable is labeled "CAT5e" logo. In actual use, in the 100M bandwidth network, the reason why the super five is preferred is that the signal attenuation is smaller, the anti-interference ability is stronger, and the interference level is only one quarter of the five types of lines.
Six types of network cable: transmission bandwidth of 1000Mbps, the outer skin labeling "CAT6" application in the Gigabit network, the performance is much higher than the super five twisted pair.
Super six types of network cable: also known as 6A network cable, labeled "CAT6e", can support 10G network, twice the size of the six types of network cable.
From the above basic characteristics of each type of line can also be seen different points, and the other difference is that there are cross keels in the middle of the six types of lines, and five types of lines do not. The two twisted wires of each pair of twisted pairs are twisted to a different extent, and the six types of twists are higher than the five types. The six categories are wider than the five categories.
The core of the 100M network cable is 8 cores, but only 4 of them are used for uploading and downloading, and 8 are required for Gigabit network cables. In actual engineering, hundreds of megabytes of switches generally use super five types of network cables; gigabit switches have six budgets, but at least five categories; gigabit main switches and six types of network cables.
