What is a characteristic of a centralized power node?

A centralized power node is designed to deliver power to various components within a telecommunications network, particularly those located outside of the main central office. One of its primary functions is to provide power for fiber-optic nodes and outside plant amplifiers, which are essential for signal amplification and distribution over long distances. This characteristic enables the centralized power node to support the overall functioning of the network by ensuring that critical components, such as those used for signal processing and distribution, receive the necessary power.

In contrast, other options do not accurately describe a centralized power node's functions or requirements. For instance, suggesting that it only powers customer premises equipment misrepresents its broader role in supporting more extensive network components. Asserting that it primarily operates on solar energy restricts its operational flexibility; centralized power nodes can draw power from various sources to ensure reliability. Additionally, claiming that it requires multiple independent power sources underestimates the system's ability to function efficiently with a well-designed centralized power infrastructure. Overall, option B best captures the essence and functionality of a centralized power node within the telecommunications framework.
