Demand for high bandwidth services by end users continues to grow rapidly. To meet current and future demand for services, such as internet TV, 4K/8K video, online gaming, VR/AR, and IoT, operators are deploying FTTH (Fiber-to-the-Home) to the consumer’s home or business. It provides low latency, high reliability, and high-speed internet connections. This article provides some information about FTTH. What is FTTH? FTTH is the installation and use of optical fiber, passive optical network (PON) technology, and GEPON from a central office (CO) directly to individual buildings such as homes, apartment buildings, businesses, and schools by providing high-speed internet access. It increases connection speeds and reliability for broadband networks compared to copper. How Does FTTH Network Work? The FTTH network is realized with an ODN (Optical Distribution Network). It is the network between the OLT (Optical Line Terminal) in the CO and the ONU (Optical Network Unit) in the end-users h
