It’s a C-Band ASE light source 1550nm fiber laser. The spectral flatness is 2db. Gain flattening fiber ASE broadband light source is based on the ordinary broadband light source by adding a gain flat technology. And optimize the light source structure, The output spectral flatness reaches 2dB. While having a higher output power. Suitable for optical fiber sensing applications.
