The technology of passive optical access networks (PON) for more than 20 years of its existence has gone from APON to NGPON2. The latter was standardized in 2015. With the improvement of PON technology, the bandwidth of such access networks and, accordingly, the speed of data transfer per user increased. At the same time, both capital and operating costs grew per user.
The researches aimed at reducing these costs, were carried out in different countries. The transition to Long-Reach PON (LR-PON) technology may be solution. LR-PON networks are long-range optical networks unlike from GPON allow us to increase the distance from the optical line terminal (OLT) to 100-120 km, to provide consolidation of OLT in a ratio of 1:50 or better convergence network access and metro network, reduce electricity consumption. The use of LR-PON technology provides economical deployment of the access network in the regions with both high population density and low population density, i.å. solve the problem of «digital inequality».
The largest contribution to the solution of problems on the study of various approaches to the construction of LR-PON networks was made by the DISCUS consortium (The DIStributed Core for unlimited band-width for all users and services).
