Which of these are concerns for radio frequency over glass (RFoG) and fiber-to-the-x (FFTx) systems?

The concern regarding how and who will provide AC power to the optical network terminal (ONT) at the customer premises is pivotal because the ONT is essential for converting the optical signals back into electrical signals for use in the home or business. This device requires a constant power supply to function effectively, and without proper consideration of power provision, the reliability and performance of the entire system can be compromised.

In the context of RFoG and FFTx systems, where the technology transitions signal formats to serve various applications, ensuring that the ONT has a reliable source of power is crucial for maintaining uninterrupted service. If the ONT cannot access adequate AC power, it can lead to service interruptions, increased customer dissatisfaction, and potential field service visits to troubleshoot or resolve power-related issues.

While fiber splice losses, minimizing fiber use, and enhancing wireless coverage are important operational considerations, they do not directly relate to the functionality of the ONT as power availability does. Therefore, power provision is a critical concern in the effective deployment and operation of these technologies.
