What is the correct sequence of fiber-optic network architecture up to customer premises?

The correct sequence of fiber-optic network architecture leading up to customer premises begins with the most foundational components and progresses to the final point of delivery.

In this context, the sequence typically starts with the fiber terminating at a feeder point, known as fiber-to-the-feeder (FTTF). This represents the initial connectivity where optical signals are routed to various neighborhoods or districts. From there, the architecture moves to fiber-to-the-neighborhood (FTTN), where the fiber extends closer to the demographic areas, connecting to local distribution networks.

Next in the sequence is fiber-to-the-curb (FTTC), where the fiber reaches the vicinity of customers, generally at the curb or edge of the property. This stage allows for high-speed connections to be distributed over copper or wireless mediums to the end users. Lastly, fiber-to-the-home (FTTH) signifies the final step where fiber optics reach directly into residential properties, providing the ultimate in speed and service quality to homeowners.

By outlining this flow from the headquarters or central office through various stages—feeder, neighborhood, curb, and finally to the home—one sees that the correct sequence accurately reflects the hierarchical deployment of network infrastructure necessary to deliver fiber-optic services effectively and efficiently to customers.
