Which sequence represents the progression of fiber optic network architecture from central office toward the home?

• 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)

From the central office, fiber travels outward in steps that bring the signal closer to the customer: first the feeder fiber extends toward distribution points, then it enters the neighborhood’s distribution network, then it reaches the curb or pedestal near the street, and finally the final drop delivers to the home. This outward progression—feeder, neighborhood, curb, home—best represents how fiber optic architecture is deployed toward the user. The other sequences disrupt the order by placing the final home connection earlier or jumping between stages in the wrong order, which doesn’t match how the network physically grows outward from the central office.
