FIBER IN METAL TUBES

Harsh Environment Cable (HEC)

Underground Optical Cable for Harsh Environments

Our Harsh Environment Cable (HEC) performs in the most demanding conditions imaginable. The configuration ensures maximum crush resistance and tensile strength. It functions at extreme temperatures, ranging from -60°C to +800°C (-76°F to 1472°F). 

The production process includes a hermetical seal on the inner layers, contributing an additional dimension of protection against corrosive agents. As many as 144 optical fibers can fit into a single cable, making the underground optical cable ideal for fiber optic sensing and data transmission in the most challenging environments.
