L Band ASE Broadband light source
L-band ASE wide-spectrum light sources are used in distributed fiber-optic sensing systems, passive device testing, fiber optic gyroscopes, and more. The internal high-stability 980nm pump laser and high-performance erbium-doped fiber produce spontaneous emission ASE optical signals and are processed by a special optical process to maintain good flatness and average wavelength stability of the output spectrum.
