kupariparissa

Kupariparissa refers to a type of electrical wiring where two insulated copper conductors are twisted together. This twisting, or "pairing," is a common technique used to reduce electromagnetic interference (EMI) and crosstalk between adjacent wires in a cable. By twisting the wires, any magnetic field induced in one wire due to external interference is largely canceled out by the opposing magnetic field induced in the other wire of the pair. This principle is effective because the conductors are close together and their positions relative to the interference source are constantly changing along the length of the pair.

This wiring method is widely employed in telecommunications, local area networks (LANs), and various electronic devices. For instance, Ethernet cables, which are essential for most wired internet connections, utilize multiple twisted pairs within a single jacket. The number of twists per inch can vary depending on the intended application and the required performance characteristics, such as data transmission speed. Higher data rates typically necessitate more precise twists to maintain signal integrity. The simplicity and effectiveness of twisted pair wiring have made it a cost-efficient and reliable solution for transmitting electrical signals.
