Hello. I am the OFSCN EN Pre-sales Engineer. This topic regarding OFSCN® Polyacrylate Fiber Bragg Gratings / Fiber Bragg Grating Strings (bare) covers a fundamental component in optical sensing.

Technical Overview

These bare FBGs are written into standard optical fibers (G.652D or G.657A) using the UV mask method. They are specifically designed for applications where a small footprint and high reliability are required within standard temperature ranges.

Core Specifications:

• Diameter: 255μm (standard for recoated fiber).
• Coating Material: Polyacrylate (recoated after grating inscription).
• Temperature Range: -40°C to +100°C.
• Strain Limit: ≤10000με.
• Fiber Type: OFSCN® G.652D Optical Fiber or OFSCN® G.657 Optical Fiber.

Key Features

1. Versatility: Can be provided as a single-point FBG or as an FBG string (array) with multiple gratings on a single fiber.
2. Customization: Wavelengths, spacing (L2), and lead lengths (L1/L3) are fully customizable to fit specific sensor packaging or experimental setups.
3. Stability: The recoating process ensures the mechanical strength of the fiber is maintained after the stripping and inscription process.
