Which fiber-to-the-x (FTTx) topology uses a passive optical network (PON) for a P2MP connection?

The correct answer is Fiber-to-the-home (FTTH), as this topology is designed to provide high-speed internet access directly to individual homes using a passive optical network (PON). In an FTTH setup, fiber optic cables carry the data all the way to the premises, allowing for a point-to-multipoint (P2MP) connection. This means that a single optical fiber can serve multiple homes, which significantly increases the efficiency and scalability of the network.

FTTH leverages passive optical components, which do not require electrical power to operate, making the deployment more cost-effective and energy-efficient. The PON architecture used in FTTH minimizes the need for active electronic equipment throughout the network, which further enables lower operational costs and easier maintenance.

Understanding this topology is essential as it reflects the shift towards more sustainable and high-capacity fiber optic connections that cater to residential users, ensuring that they receive superior internet service compared to older technologies. Other FTTx options, while also involving fiber optics, typically use different methods of distribution or might incorporate active components that do not fit within the passive definition of PON.
