GPON distance suitability: GPON is suitable for distances up to approximately how many kilometers?

GPON reach is governed by the optical power budget between the OLT and the farthest ONU. The system must deliver enough optical power to the ONU receiver while accounting for fiber loss, splitter loss, and connector losses. With typical single‑mode fiber attenuation (around 0.35 dB/km) and the losses introduced by common splitter configurations, the design can usually accommodate a farthest ONU at about 60 km. Shorter links (around 30 km) are common and offer more margin, but pushing toward 90 km or 120 km would exceed the standard GPON budget without special hardware or techniques. So, the practical maximum distance GPON is suitable for is roughly 60 km.
