The cost of splicing each break could be around $300 per splice, so that's $1500 for the splicing. Even less expensive than that is using pre-terminated fiber cable. A mechanical splice would also require cable prep time, plus the $5. The "per splice" rate is the most. The short answer: in current remuneration models for fibre optic projects, splicing work is typically billed at 8 to 15 euros per fibre — depending on volume, installation location and documentation requirements. Commercial building installations with 100-200 network drops generally range from $15,000 to $30,000. Understanding these factors can help businesses and individuals budget effectively for fiber optic.
