What is the maximum distance of an ONT telephone line?

The distance (usually 1 km outdoors) is affected by the quality of telephones and telephone lines, as well as the number of phones connected. The poorer the quality of telephones and telephone lines, the shorter the distance. The more telephones connected, the shorter the distance.
Note: The cable cannot be routed outdoors, because the equipment may be damaged when lightning strikes.

The maximum physical transmission distance of the ONT is 60 km. The physical distance between the farthest ONT and the nearest ONT can be up to 20 km.

Theoretically, the maximum transmission distance supported by the pots port of the HG ONTs are 1000m. But in the actual environment under the influence of the phone resistor and line resistance, the transmission distance will be reduced
