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

Fiber-to-the-curb (FTTC) and fiber-to-the-node (FTTN) are two different network topologies that utilize fiber optic technology to deliver internet services, but they differ primarily in how close the fiber connection is to the end user.

In FTTC, the fiber terminates closer to the end user, typically at a curbside location, which means the distance that the signal needs to travel over copper or coaxial cable to reach the customer's premises is reduced. This proximity allows for better performance and higher speeds because there is less potential for signal degradation across the copper segment. As a result, FTTC typically requires fewer RF (radio frequency) amplifiers or signal boosters because the signal does not have to travel as far over the less efficient copper lines. This closer termination of the fiber helps maintain stronger signal quality and bandwidth.

The other options do not capture the primary technical distinction as effectively as this one does. By understanding the proximity of the fiber termination point in FTTC compared to FTTN, it becomes clear why fewer RF amplifiers would be needed in the FTTC setup.
