Nowadays, one of the trends of information and communication networks development is the provision within the shortest time of a larger number of telecommunication services to network users. Currently, connection of subscribers to xDSL communication channels provided by public switched telephone networks (PSTN) is widespread. Providers of classic telephony make active use of these networks due to the low cost of the connection of a subscriber. An obvious disadvantage of this connection type is the limited data transfer rate. Some Internet providers rapidly develop ETTH (Ethernet To The Home) networks. The advantage of ETTH networks is the targeting of the delivery of communication services to subscribers. One of the disadvantages is the operation of a network at the Ethernet level with all typical for this protocol features. The practice of optical networking has existed for many years; however, the basic approach to optical networking is based on the use of active equipment from the access node to users. PON-based (Passive Optical Network) FTTH architecture (Fiber To The Home) is as a rule, compatible with the Ethernet Protocol. The article shows the advantages of the deployment of PON-based FTTH networks, in particular, saving of fiber-optic lines in the area from the optical splitters to the Central telephone exchange or access point by using relevant ports. The article provides the description of access networks architecture applying Ethernet FTTH and PON technologies, and also discusses the prospects for further development of the above mentioned networks.
