What can excessive signal leakage lead to in a cable system?

Excessive signal leakage in a cable system can significantly interfere with other communication services, making this the correct answer. When signal leakage occurs, it allows the signals within the cable system to escape into the surrounding environment. This can disrupt other nearby communication systems, including wireless networks, emergency communication systems, or other broadcast services, leading to potential degradation of service and performance.

Furthermore, the presence of unwanted signals in the environment can cause problems for both the cable system itself and any other system operating in or near the affected frequency bands. This interference can result in a variety of issues such as loss of quality in communication, dropped calls, or missed transmissions, emphasizing the importance of maintaining proper signal integrity and minimizing leakage.

Other options do not accurately reflect the impact of excessive signal leakage. Stronger signal reception would not be a result of leakage; rather, the opposite would typically occur because leakage can signal loss within the cable system. Increased revenue for service providers is not directly linked to the negative consequences of signal leakage; in fact, interference could lead to customer dissatisfaction and potential revenue loss. Improved network performance contradicts the reality of signal leakage, as it tends to degrade the overall performance of the network rather than enhance it.
