Fibre Optic PON uses light signals to transmit data, though few realize the various methods to facilitate these signals' journey.

Two main types of optical networks achieve this:

Fiber Optic Passive Optical Network

PON technology is widely adopted in telecom, supporting multiple endpoints through a single optic fibre with point-to-multipoint topology.

Optical splitters attenuate light symmetrically, introducing equal attenuation to signals upstream and downstream.

PON Network Components

A PON network comprises “Optical Network Units” (ONUs) and “Optical Line Terminations” (OLTs), with OLTs at the service provider’s end and ONUs near the receivers.

• Firstly - Active Optical Network (AON)
• Secondly - Passive Optical Network (PON)
• Reduced operational, installation, and energy costs.
• Less network infrastructure.
• No need for network switches.
