What is FTTx?
Although FTTH (or, for businesses, FTTP: Fiber to the Premises) is the most commonly referenced “Fiber to the...” architecture, there are actually many. “FTTx” refers to this group of related but functionally distinct technologies.
3 Common Subsets of FTTx:
1-FTTN (Fiber to the Node).
In this architecture, fiber is used to transport data to an access node that serves a large number of nearby customers. The “last mile” connection (which may be much longer than a mile) to individual subscribers is carried over copper lines, which are already deployed in most areas.
2-FTTC (Fiber to the Cabinet)
The next major progression from FTTN is FTTC, in which fiber extends much closer to the customer’s property. As an example, fiber might extend from a node to a cabinet that serves a few dozen homes in a neighborhood. FTTC reduces the distance data must travel over copper lines, increasing bandwidth.
3-FTTH (Fiber to the Home)
In the FTTH model, fiber continues all the way to a box on the customer’s property, typically attached to the house. This eliminates all copper use between the provider and the customer site, which skyrockets the bandwidth that can
