Fiber infrastructure
FTTH and FTTx: key differences
FTTx describes how far fiber reaches within an access network. FTTH is the application in which fiber reaches the subscriber’s home.
FTTH: Fiber to the Home
In FTTH architecture, optical fiber extends to the subscriber’s home. Termination boxes, splitters, connectors and other components serve different points of this network.
FTTx: Multiple termination points
The “x” in FTTx indicates the point reached by fiber. FTTB refers to fiber to the building, while FTTC reaches a street cabinet or curb. The remaining connection to the subscriber depends on the architecture.
How does product selection change?
Subscriber numbers, distribution points, cable routes and environmental conditions determine product requirements. Termination capacity and splitter ratio should be considered together as parts of network design.
