1545nm-1605nm 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.
Features
High output power, high spectral flatness;
Excellent average wavelength stability;
Low polarization output;
Low spectral ripple;
Excellent reliability and stability.
Applications
Distributed fiber optic sensing
Fiber grating sensing
Passive device test
Spectral analysis.
