How many pairs are there in a twisted pair cable?
Answer:
A twisted pair cable is a type of communications cable that consists of two conductors of a single circuit twisted together.
The twisting of the wires helps to reduce electromagnetic radiation from the pair and crosstalk between neighboring pairs, and improves rejection of external electromagnetic interference ¹.
The number of pairs in a twisted pair cable can vary depending on the intended use.
For example, Category 3 cables typically have 4 pairs of wires, while Category 5 cables have 4 or 8 pairs
