# Product Name: OFSCN® Multicore Fiber Bragg Gratings / Fiber Bragg Grating Strings (Bare)

## Website Link
https://www.ofscn.net/fbg-products/multicore-fbg.html

## Key Technical Specifications
* **Process**: Traditional Multicore FBGs were written using the UV phase mask method and were commonly used for the production of OFSCN® FBG Shape Sensors.

# Product Name: OFSCN® Fiber Bragg Grating Pipeline Pressure Sensor

## Website Link
https://www.ofscn.net/fbg-products/pipeline-pressure-sensor.html

## Key Technical Specifications
* **Description**: A customized application of the OFSCN® Fiber Bragg Grating strain sensor. By using custom fixtures to fix the strain sensor circumferentially around a pipe, it can measure pipeline pressure or circumferential strain.
* **Common Configuration**: Most commonly based on the **OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensor**.
* **Calibration**: Factory calibration provides strain-wavelength correlation (linear formula, unit: με/pm). Since pipe pressure depends on diameter and wall thickness, users must perform their own calibration for pressure values.
* **Installation**: Requires the purchase or customization of an **OFSCN® Installation Fixture** for deployment.
* **Other Parameters**: Please refer to the corresponding OFSCN® Fiber Bragg Grating strain sensor specifications.
