Fiber-Optic Line Cost Model v1

Executive Summary

This model quantifies fiber-optic line economics by combining material, labor, and energy inputs with CAPEX. Under typical APAC assumptions the model outputs a cost of $2.15/km and a payback period of 3.8 years. Dataset (CSV) and methods (PDF) are available for validation.

Methods

• Inputs: materials, labor hours, energy (kWh), overheads.
• Assumptions: line speed 90–120 m/min; utilization 75–85%; depreciation 7 years.
• Outputs: cost/km, total cost of ownership, payback years.

Results

Line Speed (m/min)	Utilization (%)	Cost (USD/km)	Payback (years)
100	80	$2.15	3.8
120	85	$1.95	3.2
90	75	$2.35	4.1

Sensitivity: +10 m/min line speed typically reduces cost by ≈$0.1/km (illustrative).
