Fiber to the Premises (FTTP),Fiber to the Home (FTTH), or fiber to the building (FTTB) is a broadband telecommunications system based on fiber-optic cables and associated optical electronics for delivery of multiple advanced services such as of telephone, broadband Internet and television across one link (triple play) all the way to the home or business.

Current research forecasts that the total FTTP market for equipment, cable, and apparatus will reach $3.2 billion in 2009.

Technology

Two competing FTTP technologies are Active FTTP, also called Active Ethernet, and passive optical network (PON) architectures.

Active FTTP networks utilize powered (i.e. 'active') electronic equipment in neighborhoods, usually one equipment cabinet for every 400-500 subscribers. This neighborhood equipment performs layer 2/layer 3 switching and routing, offloading full layer 3 routing to the carrier's central office. The IEEE 802.3ah standard enables service providers to deliver up to 100 Mbit/s full-duplex over one single-mode optical fiber to the premises depending on the provider. Service providers using Active FTTP technologies include YRT2.net, SureWest, iProvo, Grant County, Washington, UTOPIA, and Broadweave Networks.

Passive optical network (PON) FTTP networks on the other hand avoid the placement of electronics in the field. PON networks use passive splitters to distribute fiber to individual homes. One fiber is optically split into 16, 32, or 64 fibers, depending on the manufacturer, which are then distributed to residential or business subscribers. In PON architectures, the switching and routing is done at the carrier's central office. Service providers using PON include Verizon (FiOS), AT&T (U-Verse), and several greenfield development networks. Optical signals, once received in the home, are processed by thin film filter technology or more recently with dispersion bridge planar lightwave circuit technology so that the signal can be properly routed to the appropriate component in the home (voice, video or data).

Availability by Country

Asia

Japan

FTTH, often called FTTP in Japan, was first introduced in 1999, and did not become a large player until 2001. In 2003-2004, FTTH grew at a remarkable rate, and DSL's growth slowed. 4.63 million FTTH connections (includes 1.99 million FTTX for multifamily housing) are reported in March, 2006 in Japan.
