Extended C+L band 50mW ASE Broadband Light Source Module Type ASE-CL-ET-50-T-SM-M20
This light source outputs wavelengths from 1524 to 1611 nm in the C+L extended band, covering a spectral range exceeding 88 nm with better than 3 dB flatness. Outputting through SMF-28 single-mode fiber, it achieves a maximum output power exceeding 350 mW. It is ideally suited for applications such as fiber optic sensing and fiber optic device testing. The fiber-optic ASE broadband light source is an incoherent light source derived from spontaneous emission generated by a semiconductor laser pumped from erbium-doped silica fiber. Spectral flattening technology is also employed to achieve broadband and flat spectral output.
