From the introduction of the computer so far its appearance, interface, performance is also undergoing radical changes; USB interface in the evolution, to the emergence of Type-c; from VGA gradually to HDMI has become the most widely used audio and video interface; mouse, keyboard interface from RS232 into a PS2, and then from PS2 into USB, and then to the wireless mouse, keyboard. Over the years, why the computer interface eliminated a number of batches, or through several upgrades and updates, and the network cable no matter how to change, the network cable interface has been the RJ45 interface did not change, and has not been replaced?

Since the birth of the development of more than 30 years since 1990, whether it is home routers, computers, IPTV TV boxes and so on have used the RJ45 interface, which is only our daily contact or can see. Want to replace the RJ45 is not simply on the computer to change the interface on the line, or mainly involved in the many manufacturers with RJ45.

RJ45 as an engineering-grade products, enterprises and telecommunications carriers room switches, routers, firewalls, APs, distribution frames and other large servers and large equipment are used to RJ45 network cable interface is the main, many industrial equipment are also used RJ45 network cable interface, their high cost, so RJ45 interface must be very " dedicated", if you change the interface will experience great pain.

RJ45 interface also has many unique advantages, such as from the operation of the network cable and crystal head in the absence of electricity and other tools, just use a network cable pliers can be connected, not easy to fall off, and mechanical strength than other interfaces, such as fiber optics will require special fusion equipment and optical terminals. And RJ45 crystal head back of the snap can ensure that it is inserted into the equipment after the stability is high, will not fall off because of vibration, shaking.

Some loptop now remove the network cable interface, but for the vast majority of people does not have any impact. Because RJ45 network cable design transmission performance is stable, high bearing bandwidth, good shielding and other advantages, so the current loptop network interconnection solution is usually a combination of WiFi and USB-C to RJ45 adapters.

RJ45 network cable interface has not been replaced, nor to do smaller, thinner, lighter, it comes down to the RJ45 interface covers almost all network equipment, electronic devices that communicate through the network cable, because of its popularity, replacement cost and performance so there is no interface standard that can replace it.
