keerdpaarkaabel

A keerdpaarkaabel, also known as a twisted pair cable, is a type of electrical wiring used in telecommunications and networking. It consists of two insulated conductors, called wires, that are twisted together. This twisting serves a crucial purpose: to reduce electromagnetic interference (EMI) from external sources and to reduce crosstalk between adjacent pairs of wires.

There are two main types of keerdpaarkaabel: unshielded twisted pair (UTP) and shielded twisted pair (STP). UTP is the most common type and is used in applications like Ethernet networks and telephone lines. It relies solely on the twisting of the wires for noise reduction. STP, on the other hand, includes an additional layer of shielding, such as a metallic foil or braid, around the twisted pairs to provide enhanced protection against interference.

The twisting of the wires in a keerdpaarkaabel means that each wire in a pair is exposed to the same level of electromagnetic interference. However, because the wires are twisted, the induced currents in each wire flow in opposite directions, effectively canceling each other out. This cancellation significantly improves the signal integrity, especially over longer distances.

Keerdpaarkaabel is widely used due to its cost-effectiveness, ease of installation, and reasonable performance for many applications. Different categories of keerdpaarkaabel exist, such as Cat5e, Cat6, and Cat6a, each offering increasing bandwidth and data transfer rates. The choice of category depends on the specific requirements of the network or telecommunication system.
