What is the main difference between fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC)?

The primary distinction between fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) lies in their architecture and deployment strategy, particularly in how each method integrates fiber optics with existing copper infrastructure. FTTC deploys fiber closer to the end-user, typically nearer to the curb or street, which allows for a reduced number of RF amplifiers in the overall network setup. This placement leads to improved signal quality and potentially better performance for the end-user, as the fiber-to-the-curb configuration minimizes the distance that the signal must travel through copper wiring, resulting in less signal degradation.

By contrast, FTTN involves running fiber to a neighborhood node, which is then connected to the home using copper lines. This usually necessitates more RF amplifiers since the distance the signal must travel over copper is greater, leading to increased potential for signal loss and degradation. Consequently, FTTC can often provide a more efficient and higher-quality signal due to less reliance on copper infrastructure, which affects how many RF amplifiers need to be deployed.

Understanding this fundamental difference helps clarify the architectural advantages of FTTC, particularly in terms of fewer required RF amplifiers compared to FTTN, which ultimately enhances service quality for customers.
