Harsh Environment Cable (1/4")

Fiber Optic Sensing in Harsh Environments

Our Harsh Environment Cable (HEC) performs in the most demanding conditions imaginable. The configuration ensures maximum crush resistance and tensile strength. Moreover, it functions at extreme temperatures, ranging from -60°C to +300°C (-76°F to +572°F), and it’s a popular fiber optic sensing cable for the Oil & Gas Industry, among other harsh surroundings.

The production process includes a hermetical seal on the inner layers, contributing an additional dimension of protection against corrosive agents. In addition, as many as 24 optical fibers can fit into a single cable, making the heavily protected cable solution ideal for fiber optic sensing and data transmission in the most challenging environments.

The Harsh Environment Cable is capable of Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) in high pressure/high temperature (HPHT) settings. If this sounds like what you need from a fiber optic cable, get in touch and talk to one of our experts today. We always listen to your unique challenge and deliver a custom solution that’s perfect for you.
