Overview of PON Interfaces

Overview of PON Interfaces

Passive optical network (PON) technology is a new point-to-multipoint optical access technology. A PON network uses only optical fibers to transmit data, voice, and video services.

A PON network consists of only passive optical components. This technology has the following advantages:
  • Prevents electromagnetic interference and lightning damages generated by active electronic components.
  • Reduces failure rate of lines and devices.
  • Simplifies power supply configuration and network topology.
  • Improves system reliability.
  • Saves maintenance costs.

Theoretically, a PON network can transmit signals of any format at any rate.

PON System Architecture

As shown in Figure 20-1, a PON system consists of optical line terminal (OLT), Optical Distribution Network (ODN), and optical network units (ONUs).
  • An OLT is an aggregation device that terminates PON protocol packets on a carrier network.

  • An ODN is a passive device that connects ONUs to an OLT. It distributes data to downstream ONUs and aggregates data sent to the upstream OLT.

  • An ONU is a user-side device that provides interfaces for users.

NOTE:

The router functions as an ONU.
