What is a function of a centralized power node in a telecommunications network?

A centralized power node in a telecommunications network primarily functions to provide sufficient power for fiber-optic nodes. In such networks, fiber-optic nodes play a crucial role in delivering high-speed data over long distances, and they require a reliable and robust power supply to operate efficiently. The centralized power node ensures that adequate power is distributed to these nodes, which is essential for maintaining connectivity and performance across the network.

Maintaining a stable power supply at a centralized location helps streamline maintenance and management of the power distribution. This approach is beneficial in improving overall efficiency and reduces the complexity involved in powering numerous dispersed units throughout the network.

In context, the other options relate to concepts that do not align with the primary role of a centralized power node. Decentralizing power distribution or connecting directly to residential power lines would typically lead to complexities rather than efficiencies, while reducing power consumption is a broader goal that may be supported by effective power management but is not the direct function of a centralized power node.
