A passive optical network (PON) is a point-to-multipoint fiber-optic system where a single OLT at the service provider's central office communicates with multiple ONUs near end users through an optical distribution network (ODN) using passive splitters . The downlink, or downstream direction, refers to data sent from the OLT to the ONUs. All ONUs receive the optical signal, but each ONU only processes the data intended for it, discarding other traffic .
Downlink transmission in PONs relies on bandwidth allocation to manage multiple ONUs efficiently. The OLT performs the following steps:
In PON downlink transmission, the OLT centrally manages bandwidth allocation and signals each ONU with its designated data segment. ONUs then receive only the relevant downstream traffic, leveraging TDM and WDM technologies to maintain high-speed, reliable, and energy-efficient communication. This architecture enables PONs to deliver broadband services effectively to multiple users over a single optical fiber while minimizing complexity and operational costs .
