cable is mainly used for industrial purposes and not so much in a home or business. So if you were the kind of person that is going to make their own custom cables for your network, typically you would buy a bulk roll of twisted pair cable and then you would have to wire them correctly and then attach RJ45 connectors to each end. So to do this you would have to remove the protective sheathing at each end of a network cable to expose the wires. And this is done by using a cable stripper. The cable is inserted into the cable stripper and then the outer sheathing is removed to expose the wires. And then you would insert the cable into a wire crimper to attach an RJ45 connector. But before you touch the connector, the wires in the cable have to be arranged in a certain order. And that order will be different depending upon the purpose of the cable. So for example the most common types of twisted pair cables that are used in a local area network, are straight

different types of twisted pair cables, we also have to talk about the categories of twisted pair cables. And these categories are called CAT 3, CAT 5, CAT 6, and CAT 7. And the difference between these is a maximum speed that they can handle without having any crosstalk or interference. The numbers
of these categories represent the tightness of the twists that are applied to the wires. And as you can see on the illustration of the categories and speeds of the different twisted pair cables So as you can see, the speed ranges from the lowest category which is CAT 3 at 10 megabits per second and all the way up to CAT 6a and CAT 7 which has speeds of 10 gigabits per second. Now most networks today would use at least CAT5e on their networks. Because most networks would be running at least at gigabit speeds. So CAT 3 and CAT 5 are slower than gigabit and are pretty much obsolete today.But of course if you're running a network that can handle 10 gigabit speeds, you would have to use CAT 6a or CAT 7 on your network. But even if you have an older network that's running slower speeds, you can still use CAT 7 because it is backward compatible. CAT 7 is actually a shielded twisted pair version of CAT 6a. And finally the latest version is CAT 8. Now CAT 8 is the ultimate copper cable. It's a shielded twisted pair cable which has a delivery speed of 40 gigabits per second up to a distance of 30 meters, which is 4 times faster than CAT 6a or CAT 7.
