GPON OLTs support speeds up to 2. The more advanced XGS-PON OLTs provide symmetrical 10 Gbps capabilities, meeting the demands of high-bandwidth applications. In modern communication networks, optical line terminal (OLT) is the core device to realize point-to-multipoint (P2MP) in passive optical network (PON) architecture. The OLT serves as the core aggregation device in Passive Optical Network (PON) architectures, connecting optical splitters and. When selecting the best optical line terminal for your network infrastructure, prioritize compatibility with your existing GPON or EPON system, required port density, and power efficiency. They convert electrical signals from equipment managed by a service provider to fiber optic signals readable by a PON. Their main functions include.
