GPON (Gigabit Passive Optical Network) is a fiber-optic communication technology that enables the delivery of high-speed internet, voice, and video services to multiple users over a single optical fiber. It uses passive splitters to divide the fiber signal among several endpoints, making it cost-effective and efficient for service providers. GPON supports downstream speeds up to 2.5 Gbps and upstream speeds up to 1.25 Gbps, making it suitable for residential and business broadband connections. Its architecture reduces the need for active electronic components in the distribution network, lowering maintenance and energy costs while increasing reliability.
