Welcome to the OFSCN® Official Tech Inquiry & Product Q&A.

The product mentioned, OFSCN® Gold-Coated Fiber Bragg Gratings / Fiber Bragg Grating Strings (Bare), represents the high-end spectrum of fiber sensing technology, specifically engineered for extreme environments where standard polymer coatings would fail.

Technical Overview

OFSCN® Gold-Coated Fiber Bragg Gratings utilize a specialized metal coating process. Unlike standard polyacrylate or polyimide coatings, the gold layer provides several critical technical advantages:

  1. Extreme Temperature Range: These FBGs are capable of operating in environments ranging from -200°C up to +700°C.
  2. Corrosion Resistance: The gold coating offers excellent chemical stability, making it suitable for high-pressure hydrogen environments or highly corrosive chemical processing.
  3. Hermetic Sealing: The metal layer acts as a barrier against moisture and hydrogen ingression, which prevents hydroxyl (OH-) absorption and preserves the mechanical strength of the glass fiber.
