GPON technology is currently the most modern, efficient and promising in a rather extensive family of passive fiber-optic networks. Based on acting in recent years, the European standards, it provides cable television operators and Internet service providers-effective solutions in the field of high-speed access to the world wide web, sustained and exceptional signal quality of television images. GPON technology also provides very substantial savings of the optical fiber, through the tree topology network architecture, and high reliability, achieved by passive elements branching. But perhaps the main advantage of this telecommunications innovation is high-speed “last mile”.
GPON technology supports the modern method of wavelength division multiplexing, which allows to substantially increase network bandwidth without upgrading their cable infrastructure. A tree topology opens up opportunities for flexible management of bandwidth of client services. Thus the GPON technology has a high enough data transfer rate, providing transparency of transport for a variety of services: SDH, Ethernet, ATM, etc.
Thus, the numerous advantages of passive fiber-optic networks and a number of their unique capabilities determines the benefits of this technology over other telecommunication architectures, particularly in terms of high speed “last mile”. This is due to the rapid spread of this innovation in the field of construction of high-speed Metropolitan fiber multi-service networks. What is GPON technology, and what is its essence?

In Itself it is simple, as all ingenious. The Central provider, providing high-speed backbone connection that connects to subscriber points in the passive optical network tree-like architecture. This creates a special intermediate nodes, which are compact passive splitters (splitters) optical type. Their passivity means that they did not require food or service.
GPON equipment, in addition to splitters, includes multiservice hardware and software platform of the station and subscriber terminals. One platform can transfer the information such a number of subscriber devices that allows you to connect the power budget and the speed of the transceiver hardware. The combination of such modern equipment allows to quickly and inexpensively deploy passive fibre optic network and upgrade of cable architecture.
Interestingly, the passive fiber-optic networks are not an invention of present days systems. The development of this technology began in the eighties in the depths of the laboratories of British Telecom. A few years after the start of development was made the first test trials, which were attended by many well-known European television. In the future, this technology has gone through many stages of improvements and modernization. The first passive networks of this type had a capacity of 155 Mbit/s. However, at the time this was enough. And only now, with the rapid progress of the Internet and digital television, this technology has proven to be really popular.
