RJ45
This is the network standard that allows internet connection. This type of cable has 8 electrical connection pins. It is also called ETHERNET cable or 8P8C connector (8 positions and 8 electrical contacts).
It is this standard that allows internet connection. This connector is physically compatible with the RJ11 connector if using an adapter.
On 10/100 Mbps RJ45 computer wiring, only 4 1~2 and 3~6 pins are used to transmit information.
In 1000 Mbps (1Gbps) transmission, the 8 socket pins are used.
Two RJ45 wiring standards are mainly common to wire the sockets : T568A and T568B.
These standards are very similar : only pairs 2 (orange, white~orange) and 3 (green, white~green) are changed.
