GPON distance distance: GPON supports distances up to approximately how many kilometers?

GPON distance is limited by the optical power budget of the passive optical network. The signal must travel through fiber and any splitters, and each element adds loss. The GPON standards define a practical maximum reach of about 60 kilometers from the OLT to the ONU, so the receiver on the far end can still detect the signal with sufficient margin. In practice, deployments with longer distances may use smaller splits or tighter budgets, but 60 km is the standard maximum. Distances like 10 km or 20 km are shorter than the maximum, and 90 km would exceed the budget and likely degrade performance, so 60 km is the correct answer.
