Problems of the integrated usage of the resources in access networks
Abstract
Integrated usage scenarios should be highlighted as a promising area for the further development of access networks. The phrase “integrated use of access network resources” is used as a generic term for three tasks, partly related to each other. The first problem involves the sharing of different components of the access network among several telecommunication companies. Joint modernization and operation of infrastructure for communications, electricity and other utilities in the access network is regarded as the second problem. The third problem is to exploit the resources of the access network when extraordinary events occur.

Working capacity estimation of symmetrical cables with film-porous-film polyethylene insulation
Abstract
It is shown that in order to control continuous processes of insulation imposition on conductive copper conductor for each type of symmetrical cable it is necessary to determine a value of linear capacity of isolated conductor. For this purpose analytical expression of working capacitance, allowing to determine size of linear capacitance of cable pair with film-porous polyethylene insulation of cores, has been obtained. On the basis of this research the practical recommendations have been given for adjustment of automatic system of setting up the cable capacity when insulation is applied on an extrusion line.

Generations of F1G−F5G fixed networks. Part 2
Abstract
The second part of the paper provides a brief overview of the materials developed by the E TSI ISG F±G research group, which define the basic principles for building fifth generation fixed networks F±G in the nearest future. The requirements for F±G networks and their basic characteristics are considered: Enhanced Fixed Broadband (eFBB), Full-Fiber Connection (FFC), Guaranteed Reliable Experience·(GRE) and guaranteed reliable provision of GRE services. The architecture of F±G networks is described and typical service scenarios that will be supported by the new network infrastructure based on the concept of "fiber to everything and everywhere" FTTE are listed.

Stability of coherent receiver DSP algorithms to the rapid polarization rotation caused by lightning discharge
Abstract
In this paper stability of digital signal processing (DSP)¸ algorithms of coherent receiver to the rapid polarization rotation caused by lightning stroke in an optical power ground wearer (OPWG)¸ by numerical simulation has been investigated. It is found that the rate of polarisation state (PS)¸ change is the most important parameter determining the increase in the receiver bit error rate ·BER¸. A detailed analysis of the DSP algorithms operation under the conditions of fast SP rotation has shown that the reason of the error rate growth is the limited speed of resynchronization and adaptive filtering blocks.
