Background

The signal transmission line of general computer is mainly used for signal transmission between more than two hosts, when the signal transmission line is used for signal transmission, it mainly uses internal core wire as signal transmission, so when the signal transmission line is connected with the hosts, two ends of the signal transmission line must be respectively equipped with an RJ45 connector which can be connected with the hosts and whose upper end is equipped with a metal terminal, and said signal transmission line can be plugged into the hosts by means of the RJ45 connector, and then can be electrically connected with the circuit in the main body by means of the metal terminal, so that the more than two hosts can obtain the effect of signal transmission.

The CAT7 is a fast transmission line of the current broadband network (transmission bandwidth 600 MHz) and can reach a transmission speed of 10G at most, the CAT8 is a fast transmission line of the future broadband network (transmission bandwidth 2000 MHz) and can reach a transmission speed of 40G at most, but the wire diameters of the two are thick (CAT 7 od7.4 ~ 8 mm; CAT8 od8.2 ~ 8.5.5 mm) and the core wire diameter is thick (od 1.45 ~ 1.5 mm) due to the limitation that the conventional RJ45 connector is small in size, so that the production efficiency of the current CAT7 network is not high, and the fast network transmission line of the CAT8 can hardly be produced due to the fact that the fast network transmission line can not pass the test.
