RJ45 Ethernet Connector is a devices in a wired network are usually connected physically to a server, modem, router, or each other with Ethernet cables. Each end of an Ethernet cable has a connector called an RJ45 connector. A Registered Jack 45 (RJ45) connector is a standard type of physical connector for network cables. RJ45 connectors are used almost exclusively with Ethernet cables and networking.
Ethernet cables feature small plastic plugs on each end that are inserted into the RJ45 jacks of Ethernet devices. The term plug refers to the cable or male end of the connection while the term jack refers to the port or female end.RJ45 plugs feature eight pins to which the wire strands of a cable interface electrically. Each plug has eight locations spaced about 1 mm apart into which individual wires are inserted using special cable crimping tools. The industry calls this type of connector 8P8C, shorthand for eight position, eight contact.
Ethernet cables and 8P8C connectors must be crimped into the RJ45 wiring pattern to function properly. Technically, 8P8C can be used with other types of connections besides Ethernet; it is also used with RS-232 serial cables, for example. However, because RJ45 is the predominant usage of 8P8C, industry professionals often use the two terms interchangeably.
