High Temperature Assemblies

Fiberguide’s High Temperature Assemblies use our high temperature metalized fiber and a combination of specialized assembly techniques to provide a solution for optical sensing in sealed high temperature environments. Many of our customers’ products, systems, or manufacturing processes require using a fiber optic cable assembly to allow the opto-electronic sensing components to be positioned remotely while maintaining a seal to keep contamination in or out. The data collected is often critical to the safety, operation, or efficiency of the end application.
