A GPON OLT (Gigabit Passive Optical Network – Optical Line Terminal) is the core device used by Internet Service Providers (ISPs) to deliver high-speed broadband, voice, and video services over fiber-optic networks. It is the starting point of an FTTH (Fiber to the Home) architecture and plays a critical role in managing, controlling, and distributing network services to multiple end users.
