What disadvantage does a twisted pair transmission line have?

A twisted pair transmission line is often used for networking due to its cost-effectiveness and simplicity. However, it does have disadvantages, and one significant concern is the radio frequency (RF) loss that occurs during signal transmission.

RF loss in twisted pair lines is primarily attributed to the copper material from which they are made. As radio frequency signals pass through the line, some of the energy is converted into heat due to the resistance of the copper. This loss increases with frequency, meaning that at higher frequencies, such as those used in many modern communication systems, the efficiency of the transmission can decrease, causing weaker signals at the receiving end. As a result, this loss can diminish the overall performance of the transmission, especially over longer distances.

The other options present various issues that may be associated with twisted pair cables but do not directly address the inherent disadvantage in terms of performance. For instance, high costs and low temperature tolerance are not characteristics that apply broadly to twisted pair cables, especially when compared to other types like coaxial or fiber optic cables. Similarly, while twisted pairs do experience interference, they are designed to cancel out some of this interference due to their twisted design, which helps them perform well in environments with other signal sources. However, they still experience some
