What is the FTTx?

Fiber to the x (FTTX) is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications (sometime called "Access Network") . The term is a generalization for several configurations of fiber deployment, ranging from FTTN (fiber to the neighborhood/node) to FTTD (fiber to the desktop). The FTTx architecture consists of a passive optical network (PON) that allows several customers to share the same connection, without any active components between the OLT and ONT/ONU devices.
