pariliitinkabelit

Pariliitinkabelit, commonly known as twisted pair cables, are a type of electrical cabling that consists of two conductors, insulated from each other and twisted together. This twisting is done to reduce electromagnetic interference (EMI) from external sources and to reduce crosstalk between adjacent pairs. Each pair of wires within a cable is twisted at a specific rate, with different rates for different pairs to further minimize interference.

There are two main categories of twisted pair cables: unshielded twisted pair (UTP) and shielded twisted pair (STP). UTP cables are the most common and cost-effective type, widely used in Ethernet networking. They rely solely on the twisting of the wires to combat interference. STP cables, on the other hand, incorporate an additional layer of shielding, such as a foil or braided metal screen, around the pairs or the entire cable bundle. This shielding provides superior protection against EMI, making STP cables suitable for environments with high levels of electromagnetic noise.

Pariliitinkabelit are standardized by various organizations, with categories defining their performance characteristics, such as bandwidth and frequency response. Common categories include Cat5e, Cat6, Cat6a, and Cat7, each offering progressively higher data transfer rates and better noise immunity. The connectors typically used with twisted pair cables are RJ45 for Ethernet networking. These cables are fundamental to modern data communication infrastructure, facilitating the transmission of digital data over local area networks.
