Background

RJ45 is one of the information (i.e., communications outlet) connectors in wiring systems, consisting of a plug (connector, crystal header) with 8 recesses and 8 contacts and a socket (module). RJ is an abbreviation for Registered Jack, meaning "Registered Jack". RJ is the interface in the FCC (federal communications commission standards and regulations) that describes public telecommunication networks and RJ45 for computer networks is the common name for a standard 8-bit modular interface.

And the terminal network wiring is carried out by adopting twisted pairs. The crosstalk of twisted pair wires has been minimized and reduced by the twisting of the two wires, but at the time of access to the terminal, through at least one set of network splices, there is no way to reduce crosstalk in the splices. The crosstalk generation has an influence on network delay, and high delay has a great influence on performance attenuation when applied to a high-speed network, and even bandwidth cannot be well utilized, so that bandwidth loss is caused.
