  • Difference Between Single-mode and Multimode Fiber

    The main difference between single-mode and multimode optical fiber is the size of the core. Single mode fiber has a core that measures around 5um while the multimode fiber core measures 50um or more. Because multimode fiber is thicker, it can accommodate more signals for greater bandwidth.

    A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror.
