Er-Doped Fibers

Erbium-doped fiber is known for its high gain, broad gain bandwidth, and low noise around the 1.5 μm wavelength, which aligns with the low attenuation window of communication fibers. This makes it widely utilized in DWDM optical transmission networks and CATV networks for amplifying optical signals. It features high conversion efficiency, precise gain spectrum, and excellent batch consistency, meeting the stringent requirements of optical amplifiers.
