In the past ten years, with the continuous development of science and technology, we have witnessed the upgrading of the integrated wiring industry. The CAT-5 and CAT-5 cables initially used have been gradually eliminated by the market. At present, CAT-6, CAT-6, CAT-7 and CAT-7 cables are the mainstream.
So, today we will discuss the differences between the next six, super six, seven, and super seven network cables? The transmission frequency of Category 6
Network Cable is 1MHz～250MHz, and the comprehensive attenuation crosstalk ratio (PS-ACR) of Category 6 wiring system should have a large margin at 200MHz.
It provides twice the bandwidth of Category 5, Category 5 cable is 100M, Category 5 Super is 155M, and Category 6 is 200M. The transmission performance of Category 6 wiring is suitable for applications with a transmission rate higher than 1Gbps.
Super Category 6 network cable is also called 6A, which can support 10 Gigabit Internet access. At present, the maximum can reach 500MHZ, which is twice the size of Category 6 network cable. At present, 6A is divided into two types: unshielded and shielded. Unshielded is similar to Category 6 in appearance. , The details are more obvious, 6A's lay length is more dense,
Moreover, the conductor is relatively thick. The most important change is the change on the PVC outer cover. The addition of plastic rods or the PVC outer cover is made into a zigzag shape to improve the external crosstalk test index.
The shielded type Super Category 6 network cable, this kind of shielding uses a pair-to-pair shielding structure, which is very different from the traditional shielding. This type of pair-to-pair shielding can prevent the interference of the unpaired core to other cores. To prevent external interference, it can also enhance its own signal attenuation value to minimize,
higher cost. Category 7 network cable is no longer an unshielded twisted pair, but a shielded network cable. Category 6 has UTP unshielded structure and FTP shielded structure. This is the main structural difference.
In the seven-category cable, each pair of wires has a shielding layer, and the four pairs of wires together have a common large shielding layer. From the physical structure point of view, the additional shielding layer makes the seven types of lines have a larger wire diameter. From the perspective of transmission performance, Category 7 network cables can provide a comprehensive attenuation-to-crosstalk ratio of at least 500MHZ and an overall bandwidth of 600MHZ, which is more than twice that of Category 6 and Super Category 6, and the transmission rate can reach 10Gbps.
The biggest difference between CAT7 network cable and CAT7 network cable is that the bandwidth of CAT7 network cable is 600MHZ, and the belt type of CAT7 network cable is 1000MHZ. This is the most fundamental difference in the performance of the two network cables.
CAT7 network cable and CAT7 network cable Compared with CAT6 network cable and CAT6 network cable, more changes are in the connector. CAT6 and CAT6 cables are still the traditional RJ45 structure, but CAT7 and CAT7 cables are still the traditional RJ45 structure. The network cable, the currently approved structure is all non-RJ45 type.
There are mainly Simon's TERA Category 7 connectors and Bel Stewart's Super Category 7 ARJ45 jacks and twisted pair connector interfaces.
ARJ-45 adds 4 connection contacts on the basis of RJ-45 (the highest transmission is 500MHZ, the 4 contacts of 1, 2, 7, and 8 work). The ARJ-45 interface is 1, 2, 3, 4, and 5 ,6,7,8 these 8 contacts work, the highest transmission is 2000MHZ.
With the development of the information age, people’s demand is also increasing. In the integrated wiring industry, as far as the current consumption market level of the domestic wiring industry is concerned, for a long period of time, Category 7 and Category 7 network cables It still meets people's demand for bandwidth.
