Selecting the Correct RJ45 Connector Before Buying
If you’re a beginner to network installation, I guess you will be confused about terms such as RJ45, 8P8C, modular plug, and so on. All of these terms are related to devices that are attached to the end of Ethernet cables. We’re talking about all things about RJ45 connectors here to let you have a better understanding of them.
The modular connector system was developed by AT&T in the 1960’s and 1970’s to take the place of bulky phone connectors and their labor-intensive installation. This new connector system offered simple, quick, and convenient setup that could be customized on-site by a technician or installed by the user in the home. The line has expanded over the years to include data communication mainstays, like the RJ45, which was developed for computer networking. In fact, RJ45 connectors are commonly referred to as Ethernet Connectors.
Do you know what “RJ45” means in the RJ45 connector? Let me explain it. “RJ” is the abbreviation of “registered jack”, which originally means a standardized telecoms network interface for voice and data devices connection. It was first defined in the USCO (Universal Service Ordering Code) of Bell System and in the 1970s, it was licensed by FCC (Federal Communications Commission) to maintain the compatibility between customer devices and telephone service provider equipment. “45” means the listing number of networking interface standards.
