What is the difference between FTTN and FTTC topologies?

The correct choice highlights the fundamental characteristic of FTTC (Fiber to the Curb) in comparison to FTTN (Fiber to the Node) regarding the distribution of fiber in relation to the customer premises. FTTC involves running fiber optic cables closer to the end user—typically to a distribution point near the curb or street—before transitioning to copper or coaxial lines for the last few meters to the customer’s home.

This proximity to the customer means there are fewer points of signal degradation or amplification required, allowing for a more efficient connection. In contrast, FTTN connects the fiber network to a central node located a greater distance from the customer, necessitating more complex infrastructure with additional RF amplifiers to boost the signal over the longer copper stretches to reach the end user.

Therefore, the design of FTTC allows for fewer RF amplifiers between the fiber distribution point and the customer premises, resulting in potentially higher quality and speed of service when compared to FTTN. This arrangement effectively minimizes loss and interference that often occurs with longer runs of copper, enhancing the overall performance of the broadband service provided to the end user.
