What is PON?
PON stands for Passive Optical Network. This technology utilizes fiber-optic cables to deliver broadband internet services directly to users. PON is distinguished by its use of passive components, which means it does not require electrical power to function, unlike active optical networks. The passive nature of PON allows for reduced operational costs and increased reliability.
PON technology primarily involves three key components:
Optical Line Terminal (OLT) – This device, located at the service provider’s central office, converts electrical signals into optical signals to be sent over fiber-optic cables.
Optical Splitters – These are passive devices that split the optical signal into several downstream signals for multiple users. They enable a single fiber line to connect to multiple end-users without the need for additional power sources.
Optical Network Units (ONUs) – Located at the customer premises, ONUs convert optical signals back into electrical signals for use by devices such as routers and computers.
How Does PON Work?
