What’s FTTN?

FTTN (fiber to the node or fiber to the neighborhood) deployment, the optical fiber terminates in a cabinet which may be as much as a few miles from the customer premises. The cabling from the street cabinet to customer premises is usually copper.

One of the main benefits of fiber to the node and similar systems is the ability to deliver data over more efficient fiber optic lines, rather than other lines with greater speed restrictions. The remaining area from the node to an individual destination, often called “last mile” service, can be achieved with copper or other types of wire. FTTN systems often use coaxial or twisted-pair cable in order to achieve delivery to multiple customers.

Along with fiber to the node, other types of similar systems include fiber to the pole (FTTP), fiber to the curb (FTTC), and fiber to the home (FTTH). FTTC and FTTH, as well as other alternatives, run the common line further toward the end destination than fiber to the node, which is one reason why service providers may favor a fiber to the node system in a given neighborhood.
