What is fiber to the x (FTTx)
With increasingly growth in optical fiber communication network industry technology, Smart Cities and Smart Power grids demand for high-speed broadband internet access and wireless service have continuously been on the raise in rect years. (FTTx) also described as fiber to the x, is a collective term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. FTTx offers high-bandwidth capability of optical fibers and a wide diversity of services (e.g., data, POTS and video) at a low cost since a number of end-users can share bandwidth on a single fiber and also that all outside plant equipment is passive.In today’s increasingly fast-paced, interconnected world FTTx unprecedented growth has brought fiber closer to the end user.
However, the need for high-speed broadband internet access and reliable wireless service is more acute than ever. Over the years, FTTx has become widely applied network architecture, it has changed the infrastructure technology & supersede PON and GPON Technologies.Single-mode optical fiber possess almost an unlimited bandwidth is now the transport medium of choice in long-haul and metropolitan networks. FTTx also helps to explain how close fibre goes to the end user depends on the type of architecture used, hence the use of the variable x, which is used to explain that there are several versions of architectures that can be used.Fibre can be deliver to the end user’s home, curb, building, premises, desk and neighbourhood. There are several architectures such as fibre-to-the-home (FTTH), fibre-to-the-curb (FTTC), fibre-to-the-building (FTTB), fibre-to-the-neighbourhood (FTTN), fibre-to-the-office (FTTO) and fibre-to-the-premises (FTTP).However, the PON architecture is commonly used for FTTx networks employs optical splitters to deliver signals to multiple users without conversion or intervention (i.e., components that generate or transform light through optical-electrical-optical conversion. Generally,
In recent years, FTTx can now be offered by many different types of carriers which includes: Incumbent local exchange carriers (ILECs) and regional Bell-operating companies (RBOCs), Rural local exchange carriers (RLECs), Competitive local exchange carriers (CLECs), Utility companies, Municipalities Etc. Once the FTTx network is deployed, each subscriber connection requires additional tests to ensure service quality. With different network destinations, FTTx can be categorized into several terminologies, such as FTTH, FTTN, FTTC, FTTB, FTTP, etc. Service providers are running optical fiber much deeper into the access network in order to deliver higher bandwidth that makes it possible to offer multiple high performance voice, video and data services to customers. The diffusion of fiber into the access network is often called the Fiber-to-the-X (FTTx) network. More importantly, there are two basic types of FTTx architectures. In a point to point (P2P) network, laser transmitters in the central office (CO) are dedicated to individual users. A more popular alternative, because of its high performance to price ratio, is a passive optical network (PON) in which the transmitters are shared among multiple users.
