kierrejohtimesta
Kierrejohtimesta, often translated as twisted pair cable, is a type of electrical wiring that consists of two conductors, each with an insulated copper core, twisted around each other. This twisting is done to reduce electromagnetic interference (EMI) and crosstalk, which are disturbances that can degrade signal quality. The twist rate, or the number of twists per unit length, can vary depending on the intended application and the frequencies being transmitted.
There are two main types of twisted pair cable: unshielded twisted pair (UTP) and shielded twisted pair
Kierrejohtimesta is categorized by different standards, such as Cat5e, Cat6, and Cat7, which define their performance
