What does the term "signal attenuation" refer to?

The term "signal attenuation" specifically refers to the reduction of signal strength as it travels through a medium, such as fiber optic cables, coaxial cables, or in the air. As the signal propagates, it may lose power due to various factors such as distance, interference, or absorption by the medium itself. This decrease in strength can affect the quality and reliability of the communication, leading to issues like data loss or diminished performance.

Understanding signal attenuation is crucial for field technicians because it impacts how well signals can be transmitted over different distances and mediums, and influences decisions regarding equipment, signal boosting, and network design. This concept is vital in maintaining optimal performance in any signal transmission system.
