The pursuit of high-speed and stable network not only lies in the upgrade of broadband and the choice of router, but also the quality of network cable is equally crucial. Among a wide range of cable options, CAT.7 stands out for its excellent performance, however, although it is regarded as the “best of the best” in the networking world, it is rarely seen in home networks, which makes many netizens feel puzzled.
?
In fact, Category 7 cables are primarily designed to accommodate the demands of 10 Gigabit Ethernet technology, however, Category 6 or Ultra 5 cables are more commonly utilized in the average home networking environment as network bandwidths are usually under a gigabit. So what exactly makes Category 7 cable different from Category 6 cable, and what makes it capable of handling 10 Gigabit Ethernet applications? Next, we'll take a closer look at these questions.
?
Category 7 network cable (CAT.7) stands out for its superior performance. It offers a combined attenuation-to-crosstalk ratio of at least 500MHz and an overall bandwidth of up to 600MHz, enabling transmission rates of up to a staggering 10Gbps. In contrast, Category 6 cable (CAT.6), although also widely used, is relatively low performance, offering a combined attenuation-to-crosstalk ratio of 200MHz and an overall bandwidth of 250MHz, with a maximum transmission rate of 1Gbps. Therefore, Category 7 cables undoubtedly have a significant advantage in terms of rate and latency. In addition, there are also significant differences in the physical structure of the two, further emphasizing the superiority of Category 7 cable.

1, wire core:
The purity and thickness of the inner core conductor of the cable is a key factor in determining the conductive properties of the cable. Category 7 10Gb Ethernet cable usually uses high-purity oxygen-free copper as the transmission conductor, and its core is thicker compared to Gigabit/100Gb Ethernet cable. This results in less signal attenuation when transmitting high-frequency signals, which ensures longer distance and more stable transmission performance.
?
2, shielding characteristics:
Category 7 network cable as a shielded twisted pair cable, each pair of its core is wrapped with a layer of aluminum foil to achieve effective shielding of external electromagnetic signals. In addition, the entire cable is also covered with a layer of public metal braid, further enhancing its shielding effect, reducing the mutual interference between the cables. However, it is worth noting that the shielded wire compared to non-shielded wire, its price and installation costs will be slightly higher.
?
3, ground function:
Ground wire, also known as grounded drain wire, its main role is to prevent electrostatic interference generated by the accumulation of electrons in the long-distance transmission process. When this interference is severe, it may even lead to errors in data packets. Through the effective grounding of the ground wire, static electricity can be introduced into the earth in time, thus ensuring the accuracy and stability of data transmission.
?
Trivia: The role of shielded network cable play, the need for the entire system are well shielded devices, and to ensure proper grounding. In the seven types of integrated wiring, all parts of the system such as cables, sockets, crystal heads and distribution frames are shielded devices, at the same time, the building's grounding system also needs to be improved to ensure that the shielded network cable can effectively play its role in preventing electrostatic interference.

The outstanding shielding performance of Category 7 network cables following the 10Gbps standard far exceeds that of ordinary network cables, and is especially suitable for scenarios with stringent requirements such as high-speed transmission, high bandwidth, shielding and confidentiality. Currently, with the widespread commercialization of 5G technology and the rapid progress of its related technologies, network bandwidth is facing the double challenge of increasing data traffic and the demand for higher transmission rates. Category 7 network cable, with its high transmission frequency of up to 600MHz and transmission rate of up to 10Gbps, as well as its ability to support 10/100/1000/10GBASE-TX Ethernet data transmission, will undoubtedly become the ideal choice for adapting to the future development trend of 5G.
