All about Passive Optical Networks

Passive-Optical-NetworkWhen you read or hear PON, you are discussing a passive optical network. While it is a commonly used type of network, some may not understand what a passive optical network is or how it works. Here is a basic overview of passive optical networks.

What is a Passive Optical Network?

This type of network is a telecommunications network that uses fiber optic lines to transmit data. It is considered passive because the splitters used to route the data are unpowered. These unpowered splitters send the data from the main location to a number of different destinations. A passive optical network is considered a point-to-multipoint system rather than a point-to-point system, which makes it more efficient and cost effective when providing access to the Internet for customers.

Passive Optical Network Terminology

Some acronyms that are used when managing passive optical network include the following:

  • OLT- Optical Line Terminal
    • This is the central location of the passive optical network
  • ONU- Optical Network Units
    • These are the separate destinations of the passive optical network
  • FTTN-Fiber to the Neighborhood
    • These are lines that terminate outside of buildings
  • FTTC- Fiber to the Curb
    • These are the same as the fiber to the neighborhood
  • FTTB- Fiber to the Building
    • These are lines that can extend to the buildings themselves
  • FTTH- Fiber to the Home
    • These are the same as the fiber to the building
