The homeowner later decides whether to use it for data or telephone communications. They install a standard Ethernet input known as an RJ45 jack. Many home builders nowadays run a Cat 5 cable from one central point, into every room. Cat 5 reduces crosstalk through the use of heavier jackets, better insulation, and the technique of twisting internal wires into pairs. Even the smallest amount of crosstalk will slow speeds considerably. Commercial installations require it because large numbers of cables packed together along with electrical wiring cause interference called “crosstalk”. Even if you’re totally wireless at home, your internet provider will probably have miles of Cat 5 throughout their building. Depending on their connection type, our computers, smart TVs, game machines, and home security systems may all communicate over Cat 5 wiring. While rated for speeds of 10Mbps and 100Mbps, short runs of Cat5 get gigabit speeds at times. Together, the Electronic Industries Association (EIA), and Telecommunications Industry Association (TIA) developed Cat 5 in the early 1990’s to carry high-speed network communications.
So for those of you suffering from Cat 5 curiosity, here’s a little help to bring you up to speed.Ĭat 5 stands for Category 5, but most of us simply call it “Ethernet cable”. Even when they understand that it's Ethernet cable, some still don’t really know what it means. It could refer to a tractor, a YouTube video, or a movie from the sixties. For most people, the term Cat 5 means little.
