Which of the following is a key consideration when implementing RFoG systems?

When implementing RF over Glass (RFoG) systems, providing AC power to the Optical Network Terminal (ONT) is a critical consideration because the ONT is responsible for converting optical signals back into electrical signals that can be used by network devices. If the ONT does not have a reliable source of power, it cannot perform this vital function, which would disrupt service for end users. Ensuring that the ONT is powered appropriately is essential for the overall integrity and performance of the RFoG network.

Other considerations, while important in the broader context of network deployment and management, do not directly impact the fundamental operation of RFoG systems as significantly as powering the ONT. For example, while construction costs must be managed, and cable length considerations are important for maintaining signal quality, they do not affect the basic operational capability of the RFoG system. The identification of the right frequency ranges is also crucial for optimizing transmission but falls under the category of design rather than the immediate operational requirements like providing power to essential network components.
