Topology of optical networks FTTH (Fiber-to-the-Home)
(НТУ "ХПИ", 2017) Kravchenko, Y.; Tolyupa, S.; Barabash, O.; Trush, A.; Leshchenko, O.
This article describes different architecture of access networks, access protocols; also, we analyzed the characteristics of optical networks FTTH (Fiber to the Home). The optical fiber with today is the main transport medium in the backbone and metro network. Using of fiber optic cable instead of copper cable has allowed to significantly increasing the quality of service. The greatest potential for broadband networks today have a fiber-optic technology under the general term FTTX (Fiber To The X - fiber to the X point), in which from the node connection to a specified location (point X) comes optics, and then to the subscriber - copper cable (and possible option, in which optics routed directly to a subscriber unit). Fiber optic access networks currently based on different architectures and technologies. Standards for these technologies and available of equipment make development of service-provider networks without risks. The success of their work stimulate to the dynamic development of the industry. Nowadays the PON architecture became very popular. The main factors of the most configurations of Ethernet FTTH it is the flexibility of the business model and the ability to support future services.
