These are some of the characteristics, advantages and strengths offered by GPON (Gigabit Passive Optical Network):

  • GPON's purpose is to carry Ethernet packets across much further distances with less noise and greater bandwidth.
  • Consider the GPON network as a high-bandwidth, long distance carrier for Ethernet Packets.
  • Allows for Triple Play (Internet, Voice, & TV).
  • Using Passive Optical Network with Single Mode Fiber allows long distances without the need for “active” distribution points.
  • Mass deployment scenarios.

Topology Overview

In the topology example above, you will see that the traffic typically flows from WAN to a router such as an EdgeRouter Infinity, to an EdgeSwitch 16-XG (optional), to the UFiber OLT using SFP+ ports. The UFiber OLT will then be populated with up to eight Class B+ GPON Modules (UF-GP-B+), each module will connect to a PLC Splitter with up to 128 NanoGs on each PON port. The max distance from OLT to ONU is 20km.



In this second topology example you will see that you can plan for capacity with up to 1024 NanoGs connected to one UFiber OLT. Using tools to properly calculate your link budget, you will notice that due to attenuation when planning for client capacity, you will not get the full 20km range. See our UFiber GPON - ODN Planning article for more details (Coming soon).

An analogy of this would be an airMax network where you have an Access Point (OLT in GPON) with many CPEs connected (NanoGs in GPON).
