Direct replacement of the old copper pair with fiber is a huge investment, and thus the introduction of fiber in the access networks has been phased progressively in time to match user bandwidth demands with the cost decrease of available optical devices.However, the existing copper infrastructure is unable to meet the future demand of bandwidth in both residential and business customers. These demands will only be met by the deepest penetration of optical fiber in access networks up to user s premises. The different flavors of FTTX depend on how close the fiber comes to the end user & terminology used for them.FTTN Fiber to the NodeFiber is terminated in an Active Remote Node, called Multiservice Access Node (MSAN), usually housed in an outdoor cabinet. The access multiplexer housed there carries the aggregated traffic of the neighborhood. The Access Node is connected to the Remote Node via optical cable and then from the Remote Node to the end-user premises via existing distribution network based on copper infrastructure and VDSL technology.FTTC Fiber to the Curb / FTTdp Fiber to the Distribution PointThis is very similar to FTTN, but the cabinet is closer to the user's premises, typically within 300 m. Connection to the users is based upon advanced copper based technologies, such as VDSL2 or VDSL2 Vectoring.FTTB Fiber to the BuildingFiber is terminated at the boundary of the building, such as the basement in a multi-dwelling unit. The connections between users and the building switch are not fiber but can be copper based and involve some form of transport suited to the medium available in the vertical.FTTH Fiber to the HomeFiber reaches the user s living. Each user is connected by a dedicated fiber to a port on the equipment in the Access Node (AN), or to the passive optical splitter in the Remote Node (RN) using a shared feeder and P2MP topology. The development of progressive generations of ever more sophisticated signal processing xDSL technologies transported on copper pair, such as ADSL, VDSL, VDSL2 has allowed to get more bit rate from the last segment of copper pair. However those technologies force to shorten the cooper loop length. To get interesting bit rates in those xDSL dialects, distances are quite modest, and progressively shorter, up to the point where the access line is built almost entirely of fiber. Those solutions also require interposing active remote equipment in the outside plant to make the optical-electrical conversion, which may be an inconvenience in terms of operational issues. During the recent years, network operators are facing challenges concerning the strategy to update the access networks. While some have opted to upgrade to those aforementioned xDSL solutions, most see this as a temporary fix that will only delay the inevitable road to FTTH and, thus, prefer to skip that step to future-proof their networks with an all-fiber solution. While xDSL involve some cunning and interesting technology innovations, it hardly represents an adequate response to the near-future demands of access networks. For that reason, Telecom operators has adopted FTTH architectures and GPON technology as the preferred broadband solution in access networks, in line with global trends to face the anticipated challenges in terms of bandwidth required for various services in a competitive market. There are several reasons for claiming that all-fiber access networks (FTTH), once installed, are unlikely to require any re-engineering for decades:
