Total project estimate: about $1,000-$1,600 including labor and basic terminations. Labor: 18-22 hours with testing. A 12 core fiber optic cable features twelve distinct fibers within a single cable, allowing for high-capacity, multi-channel data transmission. Single-mode fiber is designed for long-distance communication. It has a small core, about 8 to 10. The unit cost of fiber optic cables can vary from $0. 50 per meter, depending on several variables.
