How does Radio Frequency over Glass (RFoG) facilitate a transition from legacy HFC architecture?

Radio Frequency over Glass (RFoG) technology enhances the integration of fiber optics in existing hybrid fiber-coaxial (HFC) networks by enabling the use of RF signals over a fiber connection. This allows service providers to leverage their current infrastructure while transitioning to a more fiber-dominant architecture.

The reason why operating independently of Passive Optical Network (PON) communication protocols is significant lies in the flexibility and adaptability it provides within the existing HFC framework. RFoG transmits RF signals over fiber without the need to rely on PON standards, allowing service providers to maintain compatibility with the current systems, provide services, and implement fiber upgrades without completely overhauling their architecture. This makes RFoG an economical and effective solution for the transition, as it utilizes existing signal distribution techniques.

The context surrounding the other choices involves their implications for compatibility and infrastructure requirements. The notion that RFoG requires new infrastructure or cannot be integrated with existing systems contradicts the core advantage of RFoG, which is designed to work with and improve upon existing HFC architecture. Additionally, the idea that RFoG can only work with legacy systems does not align with the technology's purpose of enhancing and eventually transitioning away from older systems towards more modern fiber-based
