RV40-ZZ-0001 180 Degree Without Filter Modular Jack Vertical RJ45 Connector 1X4

RJ is the definition of the interface type and does not include the performance parameters of the interface. There are many parameters that determine the transmission rate, such as: the throughput of the network port chip; the type and quality of the network cable (is it Category 5; Category 5; or Category 6; Category 6).
The network port we generally use now is the RJ network interface, also known as 8P8C, that is, 8 grooves and 8 metal contacts. Each contact has a different function. In a 100M network, four contacts of 1, 2, 3, 6 are used. In a 1000M network, 1, 2, 3, 6, 4, 5, 7 are used at the same time. 8. Eight contacts.
