TOEM erbium doped active fiber are rare earth doped active fibers with a working wavelength close to 1.5 um, which can greatly increase the communication transmission bandwidth and reduce communication costs.
Erbium doped optical fiber have the advantages of high gain, large gain bandwidth and low noise in the 1.5 um band. Therefore, it widely used in optical communication DWDM optical transmission networks and CATV networks for amplifying optical signals. Additionally, erbium-doped fibers can also be applied in sensing fields such as LiDAR and remote sensing.
