Passive Optical Networks (PON) use a Point-to-Multipoint (P2MP) topology where a single Optical
Line Terminal (OLT) connects to multiple Optical Network Units (ONUs) or Optical Network Terminals
(ONTs) using passive splitters.
✅ Efficient Bandwidth Sharing – A single fiber from the OLT is split among multiple users, reducing
fiber deployment costs.
✅ Scalable and Cost-Effective – Supports higher user density with minimal fiber usage.
Since PON does not follow a Point-to-Point (P2P) model, the correct answer is P2MP.
