What does the term ‘attenuation’ refer to in cabling?

The term 'attenuation' in cabling specifically refers to the reduction of signal strength as it travels along the cable. This phenomenon occurs due to various factors, including the inherent resistance of the cable materials, environmental influences, and the distance the signal must travel. As a signal propagates through the medium of the cable, energy is lost, which can lead to a decrease in the quality and reliability of the transmission.

Understanding attenuation is crucial for designing effective cabling systems, as excessive signal loss can result in communication errors or the inability to transmit data accurately. These considerations are particularly important in applications where high fidelity and clear signal transmission are required, such as in networking and telecommunications.
