GPON (Gigabit Passive Optical Network) is a fiber-optic technology that provides high-speed internet access through a passive optical network architecture. It allows multiple users to share a single fiber connection, delivering broadband speeds up to 2.5 Gbps downstream and 1.25 Gbps upstream. GPON is widely used by telecom operators for efficient, cost-effective deployment of high-speed services to homes and businesses, enhancing overall network performance and reducing infrastructure costs. Its ability to support various services, such as voice, video, and data, makes GPON a popular choice for modern broadband networks.
