In a Passive Optical LAN (POL), the Optical Distribution Network (ODN) consists entirely of passive
optical components such as splitters, connectors, and fibers. These components do not require
external power, making them fully passive.
The ODN in POL follows Point-to-Multipoint (P2MP) architecture using passive splitters, ensuring
signal distribution without electrical conversion. Since no active components are present in the ODN,
it remains maintenance-free and energy-efficient.
