Multiple-Core Fiber Bragg Grating (FBG) - Multi-Core FBG Array - Seven-Core FBG - Three-Core FBG
DCYS is a professional manufacturer of multi-core FBG, providing information on multi-core FBG parameters, customization, wavelength, application, etc.; our multi-core optical fiber grating brand is "OFSCN". Bulk purchase, better price!
This product is a customizable multi-core fiber bragg grating (FBG) or FBG array. The FBG is inscribed on multi-core fiber or multi-strand fiber. Commonly used configurations are 3-core and 7-core, and they can be coated with polyimide or polyacrylate or left uncoated. They are designed to be used with "OFSCN® Capillary Series FBG Angle Sensors (FBG Inclinometers) and FBG Shape Sensors (FBG Bend Sensors)". The parameters listed for the multi-core fiber bragg grating (FBG) are for reference only. The parameters may vary slightly when the FBG sensors are fabricated, and customization is available to meet specific user requirements.
