PON – Passive Optical Networks

PON (Passive Optical Network) are optical fibre based networks which employ a point to multipoint network architecture. Passive, unpowered optical splitters are utilized to allow one fibre, often connected to the Local Exchange/Central Office, to serve a number of subscribers (typically 32 subscribers but can be as many as 128). PON technology emerged in the early 1990s and recently, PON have been deployed in support of IP convergence in many existing and green field networks. Key components of PON architecture include the OLT and ONU.
