Fiber to the Home (FTTH) is widely recognised as the optimal solution for providing broadband to new and existing communities. Unlike xDSL and cable services that take advantage of legacy telephone lines and TV cables, FTTH involves the installation of optical fiber from a central office to homes. Although the bandwidth of current FTTH services is around 10s of Mbps, the investment in fiber deployment actually future-proofs the infrastructure to meet the bandwidth demands of hundreds of Mbps to 1 Gbps per subscriber line in the next decade.
An innovative technology for FTTH implementation, Gigabit Passive Optical Network (GPON) provides unprecedented bandwidth (up to 2.5 Gbps downstream rate, shared by up to 128 premises), and a greater distance from a central office (20 to 40 kilometres, as opposed to 4~5 kilometre for DSL), allowing service providers to enable bandwidth-intensive applications and establish a long-term strategic position in the broadband market.
GPON utilises point-to-multipoint topology. A passive fiber splitter is used to split the fiber to multiple premises, thus reducing the amount of fiber and central office equipment required compared with point-to-point architectures. The passive nature of GPON eliminates the use of electricity, making it possible to install the splitter in a place where power is not easy to acquire. It is also more energy efficient.
GPON Optical Network Terminal devices deliver high-speed voice, data and video services to residential and business subscribers. They leverage the extraordinary bandwidth of GPON technology, providing a reliable, long-reach last-mile connection by extending the public high-bandwidth network to those living and working in remote homes and home offices.
