How does GPON work?
To understand how a passive optical gigabit network works, we must first look at its components. GPON consists of three main components: • Optical Line Termination (OLT): It is installed at the service provider's premises. The OLT is responsible for transmitting and receiving optical video, data, and voice signals. • Fiber Optic Splitter: This component splits the optical signal from the OLT into multiple ratios (paths) of 1:64, 1:32, 1:16, 1:8, 1:4 depending on the number of outputs required. (Maximum number of end-user outlets is 64.) Optical Network Terminal (ONT): Located at the customer premises. The ONT receives signals from the OLT and converts them (optical signals) into electrical signals that the user's devices use to provide broadband access. The GPON process begins with the OLT transmitting optical signals using wavelength division multiplexing. These signals are transmitted over fiber optic cables, reaching distances of up to 20 kilometers. At the end ...
