Installation costs can add significantly to these numbers, with estimates ranging from $10,000 to $30,000 per kilometer, depending on the complexity of the terrain and installation method. Procuring large quantities of fiber optic cable can reduce the per-kilometer cost due to. Fiber-optic cable materials typically cost $1 to $6 per linear foot, depending on fiber count and cable type. Main cost drivers include cable grade (indoor vs outdoor, armoured), distance, and labor for trenching, splicing, and termination. Singlemode cables with a small core diameter of 9 microns use high-power laser light sources to support high-speed. The cost per foot of fiber optic cable is now the lowest it's been since 2021. Labor dominates the installed price. If you buy wholesale, then you can get fiber optic cable for $0.
