Bared Fiber Bragg Grating Telecommunication Wavelength division multiplexing fiber sensor
Description:
We can offer standard Fiber Bragg Grating at the Central Wavelength from 1460nm to 1610nm. It can be used for fiber sensor and telecommunication applications. Any wavelength fiber gratings can be fabricated within a fast delivery time.
For common temperature FBG, we normally use Corning 28e optical fiber. If needs bearing higher temperature, there is ployimide coating optical fiber max 375 Celsius degree from Fibercore or relative other optical fiber.
If need more than 400 Celsius degree, it should use femoto fiber bragg grating which with special packages technology can upto 1000 celsius degree.
We also can supply with thin optical fiber 80um , 50um and microbend resistance coating optical fiber.
