Erbium-doped fiber has the characteristics of high gain, large gain bandwidth and low noise in 1. 5 μ m band, which coincides with the low attenuation window of communication fiber. It is widely used to amplify the optical signal in optical communication DWDM optical transmission network and CATV network. Erbium-doped fiber products with different absorption coefficients and different cladding diameter, through mature process control and strict testing means, to ensure that the products have high conversion efficiency, accurate gain spectrum, high batch consistency and other excellent performance, can meet the strict requirements of optical amplifier application. Erbium and ytterbium co-doped fiber is mainly used in high power telecommunication CATV optical amplifier, lidar and human eye safety laser. The erbium-ytterbium co-doped fiber has good beam quality, high conversion efficiency, and can achieve high power output and amplification of 1.5 μ m laser band. Based on the unique doping system, the optical fiber can regulate the absorption coefficient and gain spectrum to meet customer needs.
