Initially, the paper involves a thorough analysis and documentation of international literature (research publications, global standards like IEEE, European standards like EN, experimental outcomes, etc.), along with existing studies conducted by the Hellenic Distribution Network Operator (HEDNO) on these topics. Subsequently, there will be a comparative assessment between the international findings and Greek standards and regulations regarding these matters. The final stage includes presenting a substantiated and detailed recommendation for each technical issue. Where feasible, an optimal proposal for fiber optic cable installation is developed for each case, ensuring technical compliance with all constraints.
