What is FTTx

Fiber to the x(FTTx) is a term for any broadband network architecture that uses fiber opticcableinstead of the regular copper cable for last mile telecommunications. X means where the fiber optic cable ends. The generic term is used as ageneralization of several configurations of fiber deployment (FTTN, FTTC, FTTB,FTTH…), all starting by FTT but differentiated by the last letter, which issubstituted by an x as generalization.

FTTN -Fiber-to-the-node – fiber is terminated in an outdoor street cabinet up toseveral kilometers away from the customer premises, with the final connectionbeing copper.

FTTC -Fiber-to-the-cabinet or fiber-to-the-curb – this is very similar to FTTN, butthe streetcabinet is closer to the user’s premises; typically within 300m.

FTTB -Fiber-to-the-building -fiber reaches the boundary of the building, such as thebasement in an multi-dwelling unit, with the final connection to the individualliving space being made via copper or wireless means.

FTTH -Fiber-to-the-home – fiber reaches the boundary of the living space, such as abox on the outside wall of a home.

FTTP -Fiber-to-the premises – this term is used in several contexts: as a blanketterm for both FTTH and FTTB, or where the fiber network includes both homes andsmall businesses.
