What does tap loss refer to in cable systems?

Tap loss specifically refers to the reduction in signal strength that occurs when a signal is split off through a tap in a cable system. This phenomenon is quantified as signal attenuation that takes place between the input port of the tap and each of its output ports at a specific frequency. Essentially, when the signal is divided, not all of the original signal can be delivered to the individual outlets, leading to some degree of loss. Understanding tap loss is crucial for maintaining adequate signal levels throughout a network, as it directly impacts the quality and reliability of the received signals at the destination. Therefore, option B accurately captures the essence of tap loss in cable systems by focusing on the attenuation that occurs at the tap ports.
