Buying Fiber Bragg Gratings

Fiber Bragg gratings (FBGs) are narrowband reflectors constructed within optical fibers that reflect specific wavelengths of light while transmitting others. They are widely used in optical communications for wavelength division multiplexing, in fiber lasers for wavelength stabilization, and in fiber-optic sensors for strain, temperature, and pressure measurements. FBGs provide precise control over the reflection and transmission properties of light within a fiber.
Making Good Purchase Decisions
