FTTH stands for "Fiber to the Home" or "Fiber to the Premises" and is a broadband technology that uses optical fibers to deliver high-speed internet and other digital services directly to individual buildings such as households, apartment complexes, and businesses. In an FTTH system, fiber-optic cables are used to transmit data from the internet service providers network directly to the subscribers home. The defining characteristic of FTTH is that it connects optical fiber directly to residences, apartment buildings, and businesses, providing a direct connection to the internet. FTTH uses optical fiber for most or all last-mile telecommunications, transmitting data using light signals to achieve higher performance.

FTTH is a specific version of the term "Fiber to the x" (FTTx), in which the "x" represents the point in the network at which a fiber optic cable connects to provide service to buildings in the vicinity. Other versions of FTTx include:

• FTTN / FTTLA (Fiber to the Node, -Neighborhood, or -Last Amplifier): Fiber is terminated in a street cabinet, possibly miles away from the customer premises, with the final connections being copper. FTTN is often an interim step toward full FTTH and is typically used to deliver advanced triple-play telecommunications services.

• FTTB (Fiber to the Building): This term is often used interchangeably with FTTP and FTTH, and the network structure is the same.

FTTH networks offer several benefits over other types of broadband internet connections, such as DSL or copper, including faster download and upload speeds, more stable connections, and the ability to support multiple devices simultaneously. FTTH is also future-proof and cost-effective, making it a popular choice for both service providers and consumers, together with investors, municipalities, and government entities.
