Which consideration is essential for RFoG and FTTx systems?

In RFoG (Radio Frequency over Glass) and FTTx (Fiber to the x) systems, a critical consideration is how and who will provide AC power to the Optical Network Terminal (ONT). The ONT is a vital endpoint device converting optical signals to electrical signals for home or business use. For these systems to function correctly, the ONT requires a reliable AC power source, which can affect both the performance and reliability of the service provided.

Powering the ONT is crucial because without proper power management, the device may fail to operate, leading to service disruptions for end-users. Additionally, understanding who is responsible for providing this power—a service provider or the end-user—can influence the design and implementation strategy for the network. In systems where many devices rely on consistent power delivery, such decisions impact not only individual installations but the scalability of the network as well.

The other options, while relevant to various aspects of network design, do not hold the same level of immediate necessity regarding the reliability and functionality of RFoG and FTTx systems as the provision of AC power to the ONT does.
