What is the highest cable cost?

The highest cable costs can vary significantly based on factors such as the type of cable, its length, and its specific application. For instance, specialized cables like fiber optic or high-voltage power cables can reach extraordinary prices, sometimes exceeding hundreds of dollars per meter. In extreme cases, custom-engineered cables for unique industrial applications or aerospace use can cost thousands of dollars per unit. Generally, market demand, material costs, and technological requirements heavily influence these prices.
