Which progression best represents the architecture progression of a fiber optic network?

• A. Fiber to the feeder, fiber to the neighborhood, fiber to the curb, fiber to the home
• B. Fiber to the home, fiber to the curb, fiber to the neighborhood, fiber to the feeder
• C. Fiber to the neighborhood, fiber to the curb, fiber to the home, fiber to the feeder
• D. Fiber to the feeder, fiber to the home, fiber to the neighborhood, fiber to the curb

Answer: (A)

This question tests how fiber networks are rolled out from the service provider toward the customer. The deployment typically starts at the central point in the network (the feeding path) and moves outward in stages closer to each home. The fiber to the feeder stage carries high-capacity trunks from the central office to distribution points. Then fiber to the neighborhood brings that capacity into residential areas. Next, fiber to the curb places the fiber near where homes sit along the street. Finally, fiber to the home completes the connection directly to each residence. This order reflects building the network from the core toward the edge, ensuring the infrastructure progressively approaches the customer. Other sequences mix closer-to-edge segments earlier, which isn’t how the standard deployment path unfolds in practice, since you don’t reach the home before establishing the intermediate distribution points and curb-side access.
