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 offers a cost-effective solution for data transmission over moderate distances. Shielded twisted pair (STP) includes an additional layer of shielding around the conductors or pairs to provide enhanced protection against interference, making it suitable for environments with high electromagnetic noise. Different categories of twisted pair cables, such as Cat5e, Cat6, and Cat6a, denote increasing bandwidth and performance capabilities, enabling faster data transfer rates. These cables are fundamental to modern telecommunications and computer networking infrastructure.
