Er-doped and Er/YB codped fiber
Erbium-doped fiber has the characteristics of high gain, large gain bandwidth, low noise around 1.5 μm wavelength, which also matched with the low attenuation window of communication fiber, so that it is widely used in DWDM optical transmission network and CATV network to amplify optical signals. BrightCore provides erbium-doped fiber products with different absorption coefficients and different cladding diameters. Through mature processes control and strict testing methods, the products have the characteristics of high conversion efficiency, accurate gain spectrum, and high batch consistency, which can satisfy the strict applications requirements in optical amplifiers.
