Shanghai Gengyun Industrial Co., Ltd
T-AOF53306,TOEM’s erbium-doped fiber is a rare-earth-doped active fiber with an operating wavelength of approximately 1.5µm, which can amplify communication transmission bandwidth and reduce communication costs. Erbium-doped fiber offers advantages such as high gain, large gain bandwidth, and low noise in the 1.5µm band. Therefore, it is widely used in optical communication DWDM optical transmission networks and CATV networks for optical signal amplification. Additionally, erbium-doped fiber can also be used in sensing fields such as radar and remote sensing. TOEM can provide customized product services based on customer needs.
