GPON technology - new horizons of telecommunications

GPON-technology is currently the most modern, efficient and promising in a rather extensive family of passive fiber-optic networks. Based on current European standards, it provides cable television operators and Internet providers with effective solutions in the field of high-speed access to the World Wide Web, a stable signal and exceptional quality of telephoto. GPON technology also provides very significant optical fiber savings, thanks to the tree topology of the network architecture, and the highest reliability achieved through passive branching elements. But, perhaps, the main advantage of this telecommunication innovation lies in the high-speed "last mile".

GPON-technology supports the modern wave multiplexing technique, which allows to significantly increase the network capacity without upgrading their cable infrastructure. And the tree topology opens up wide possibilities for flexible management of the bandwidth of client services. In this case, GPON technology has a sufficiently high data transfer rate, which provides 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 determine the advantages of this technology over other telecommunication architectures, especially with regard to high-speed "last mile". This is the reason for the rapid spread of this innovation in the construction of high-speed fiber-optic urban multiservice networks. What is GPON technology, and what is its essence?

In itself, it is simple, like all ingenious. The central node of the provider, which provides a high-speed backbone connection, is connected to the subscriber points by a passive optical network of a tree architecture. In this case, special intermediate nodes are created, on which are placed compact passive splitters (splitters) of optical type. Their passivity means that they do not need food or service at all.

GPON-equipment, apart from splitters, includes a multi-service hardware-software station platform and subscriber terminals. And one platform can transmit information to such a number of subscriber devices, which allows you to connect to it the power budget and the speed of transceiving hardware. The combination of such modern equipment allows in the shortest time and without extra costs to deploy passive fiber-optic networks and modernize the cable architecture.

Interestingly, passive fiber-optic networks are by no means an invention of the days of current systems. The development of this data transmission technology began in the eighties in the depths of British Telecom laboratories. A few years after the beginning of the development, the first test tests were carried out, in which many well-known European television companies took part. In the future, this technology has gone through many stages of improvement and modernization. The first passive networks of this type had a throughput of only 155 Mbit / s. However, for those times it was quite enough. And only now, in connection with the rapid progress of the Internet and digital television, this technology has turned out to be really in demand.
