The FOCC9011 ASE broadband light source is a high-output, low-noise broadband light source based on the principle of spontaneous emission amplification, using doped optical fiber as the gain medium and high-performance pump as the excitation source. Combined with a gain flattening filter (GFF), it can obtain a flatter The spectral output can be widely used in scientific research, production, and engineering applications in the fields of optical communications, optical transmission, and optical sensing.
