XGS-PON uses a single fiber-optic cable to transmit data from a central location, called an optical line terminal (OLT), to multiple endpoints, called optical network units (ONUs). The ONUs are located at the customer premises and act as the interface between the optical network and the customer's devices. XGS-PON can support symmetrical bandwidths of up to 10 Gbps downstream and 10 Gbps upstream, making it capable of delivering high-speed internet access, high-definition video streaming, and other bandwidth-intensive applications. This is achieved through the use of advanced modulation techniques, such as 64-QAM and 256-QAM, which increase the amount of data that can be transmitted over the network. Another key feature of XGS-PON is its ability to support multiple virtual network operators (VNOs) on a single physical network, allowing service providers to offer differentiated services to different customer segments while sharing the same infrastructure. XGS-PON also supports time-sensitive networking (TSN) protocols, which enable the network to prioritize and guarantee quality of service (QoS) for real-time applications, such as voice and video conferencing. Overall, XGS-PON provides a high-performance and scalable solution for service providers to meet the growing demand for high-speed broadband services. Benefits

 | FTTx (Fiber to the X) is a term used in the telecommunications industry to describe the deployment of fiber optic cables to various points (or "X") in the network. The "X" can refer to a number of different locations, such as the home (FTTH), the building (FTTB), the curb (FTTC), or the node (FTTN). |
The purpose of FTTx is to provide faster and more reliable internet connectivity to end-users by replacing traditional copper-based networks with fiber optic cables, which offer higher bandwidth and greater speed. By delivering fiber directly to the premises, FTTx can provide speeds of up to 1 Gbps or more, depending on the infrastructure and technology used.
FTTH (Fiber to the Home) is the most common form of FTTx and involves running fiber optic cables directly to individual homes. FTTB (Fiber to the Building) involves running fiber optic cables to a building, such as an apartment complex or office building, where it is then distributed to individual units using traditional copper or wireless technologies. FTTC (Fiber to the Curb) involves running fiber optic cables to a street cabinet, or "curb", from which traditional copper or wireless technologies are used to connect individual homes or businesses. FTTN (Fiber to the Node) involves running fiber optic cables to a network node, which is typically closer to the end user than the central office, and using traditional copper or wireless technologies to connect individual premises.
