Our Approach Is Built on Precision, Stability & Absolute Process Control.
Optical Fibers Engineered for Extreme Oil & Gas Environments
Oil & gas operations demand materials that remain mechanically stable, chemically resistant, and optically reliable under extreme temperature, pressure, and vibration. Our specialty optical fibers are engineered specifically for environments where standard polymer-coated fibers rapidly degrade.
We manufacture metal-coated, spun, and custom optical fibers designed to withstand high downhole temperatures, corrosive fluids, mechanical stress, and long-term deployment. These fibers are trusted in distributed temperature sensing (DTS), distributed acoustic sensing (DAS), reservoir monitoring, pipeline integrity systems, and structural health monitoring.
By replacing polymer coatings with precisely applied metal layers, we eliminate thermal softening, chemical attack, and coating breakdown. This ensures stable signal transmission and extended service life in mission-critical oil & gas applications.
Oil & Gas Fiber Manufacturing – Reliability Without Compromise
Modern oil & gas sensing systems require components that integrate seamlessly with automated, real-time monitoring platforms. Our manufacturing processes use continuous inspection, digital process control, and statistical quality assurance to guarantee repeatability and long-term performance.
Each fiber is produced with strict control of coating adhesion, thickness uniformity, and mechanical integrity, ensuring predictable behavior under extreme operational stress.
Oil & Gas-Optimized

Q&A
Yes. We customize coating materials, coating thickness, fiber diameter, mechanical reinforcement, and fiber structure (single-core, spun, or multi-core) to match the exact requirements of DAS, DTS, reservoir monitoring, and pipeline integrity systems.
We provide optional high-temperature endurance testing, pressure resistance evaluation, chemical exposure testing, tensile strength measurement, and thermal cycling verification. These tests confirm long-term performance in downhole tools, pipelines, and surface monitoring systems.
Metal layers such as gold, nickel, or aluminum create a physical barrier that protects the glass fiber from exposure to corrosive fluids, solvents, hydrocarbons, and cleaning agents commonly found in oil & gas environments.
Metal coatings do not soften, crack, or chemically degrade like polymers. They provide superior resistance to heat, pressure, vibration, and hydrocarbons, ensuring stable signal transmission and longer operational life in harsh field conditions.
Metal coated fibers operate continuously up to 400 °C (752 °F) and can tolerate higher temperatures for short exposure periods. This makes them suitable for deep wells, geothermal reservoirs, and high-temperature process monitoring.
