Summary
Description NG-PON2 distribution network.png |
English:
NG-PON2 distribution network. Light from four OLTs (left), each of a different wavelength, are combined into a single fiber using a wavelength-sensitive mux. The combined fiber transports the data to and from the end-users and is equally split among the ONUs. Each ONU communicates with just one OLT at a time through the use of tunable lasers (upstream) and active filters (downstream).
