Why can't wired interfaces be slimmed down? Mainly because there is no need to do so, because the network cable in addition to connecting the computer, but also to connect the router. The vast majority of routers on the market are standard RJ-45 interfaces, the benefits and costs of thinning the network interface are not proportional to the cost, so no one is willing to do. Now the family broadband are basically universal wireless network, especially this year WiFi6 routers are beginning to appear, the wireless network is faster and more stable. So many thin and light laptops have canceled the design of the network port, and even some netizens use desktops have begun to use wireless network card.
Although wired networks are faster and more stable than wireless networks, in the usual home environment, the average user doesn't need such a high standard of network quality, and most people just need to be able to steadily watch online videos and play online games. And the wireless network as well as can fully meet the needs of these two points. So many netizens do not even use the network cable at home, directly with wireless can meet the demand for Internet access. As for those users who have higher requirements for the network, such as users who often need to download, or need to use nas to transmit ultra-high-definition video users, they usually also use desktops or more professional laptop equipment, these devices also have enough space to accommodate ordinary RJ-45 ports, there is no need to miniaturize the network port. Even for thin and light notebook users who need to use a network port for special needs, buying a USB to RJ-45 adapter cable will do the trick, and many USB TYPE-C docking stations now come with a network port function, so there is no need for thin and light notebooks to provide this kind of interface.
And for users who often need to arrange the network cable, a simple, universal interface is very practical. The RJ-45 network port is a simple crystal head replacement that can be achieved using only a network cable clamp, and even the average user can do it by following the videos on the web. However, if the network port is made into a highly integrated module like TYPE-C, once the network port has a problem, the interface is no way to replace, the entire network cable must be replaced. To know that many users home network cable are buried in the wall during the renovation, if the entire network cable is replaced because of the damage to the network interface, then the cost is very high, and you want to replace the cable without destroying the decoration is also very difficult.
Furthermore, the popular use of Class VI and even Class VII cables themselves are thicker in diameter, because more than Class VI cables need to use twisted-pair cables to anti-interference. So we look closely will find that the Category 6 cable is much thicker than the ordinary USB cable, so that it will need the same large size of the network interface connector to be fixed, and the RJ-45 network interface standard is a snap, you can securely fix the cable in the device, so that the stability of the USB TYPE-C than a lot of high stability. So now we are using the standard network port in terms of practicality and stability, or to exceed the USB TYPE-C interface a lot, there is no need to give up the existing network interface for the sake of thin and light.
