What is a PON?
PON stands for “Passive Optical Network” and, as the name says, are purely passive fiber optic access networks that allow broadband telecommunications between an OLT, located at a Telecom Operator’s Central Office, and several ONTs, located at the network user’s premises.
The transmission of communications is done in a fiber optic network, whose division of the signal is done by a device that is purely passive, called optical splitter.
Optical fiber networks that use splitters are networks with a Point-Multipoint (P2MP) architecture. Optical fiber networks without splitters, whose optical path goes from the central office to the customer’s premises without signal division, are networks with a Point-to-Point (P2P) architecture.
