Kaksoiskäyräkaapeli
Kaksoiskäyräkaapeli, also known as twisted pair cable, is a type of electrical cable consisting of two conductors that are twisted together. This twisting is done to reduce electromagnetic interference from external sources and reduce crosstalk between adjacent pairs. The conductors are typically insulated with plastic, and the entire cable may be encased in an additional protective outer sheath. Different types of twisted pair cables exist, categorized by their performance characteristics and applications.
Unshielded twisted pair (UTP) is the most common type and is widely used in Ethernet networks. It
