The full form of
Fiber PON is
Fiber Passive Optical Network.
It's a type of broadband network that uses fiber-optic cables and passive optical components (like splitters and couplers) to deliver high-speed internet and other services. "Passive" refers to the fact that the network doesn't need powered equipment in the distribution part of the network, making it more energy-efficient and cost-effective.
Fiber PON is commonly used in systems like
GPON (Gigabit Passive Optical Network), which is widely used for delivering fast internet to homes and businesses.
