ftth

Fiber to the home (FTTH), also called fiber to the premises (FTTP), is the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses to provide high-speed internet access. FTTH dramatically increases connection speeds available to computer users compared with technologies now used in most places.

FTTH promises connection speeds of up to 100 megabits per second (Mbps). These speeds are 20 to 100 times as fast as a typical cable modem or DSL (Digital Subscriber Line) connections. Implementing FTTH on a large scale would be costly because it requires installation of new cable sets over the “last links” from existing optical fiber cables to individual users. Some communities currently have fiber to the curb (FTTC) service. FTTC refers to the installation and use of optical fiber cable to the curbs near homes or businesses, with a “copper” medium carrying the signals between the curb and the end users.

How does FTTH work?

The defining characteristic of FTTH is that it connects optical fiber directly to residences. It uses optical fiber for most or all of last-mile telecommunications. Optical fiber transmits data using light signals to achieve higher performance.

Fiber to the Home access networks are basically structured like this: fiber optic cables run from a central office, through a fiber distribution hub (FDH), then through a network access point (NAP), then finally into the home through a terminal that serves as a junction box.
