C-band ASE Broadband Light Source
Product Overview
Fholink's Fiber ASE Broadband Light Source is an incoherent light source based on spontaneous emission generated by pumping erbium-doped silica fiber with a semiconductor laser. It incorporates spectral flattening technology to achieve a broadband flat spectrum. The light source covers the C-band (1528 nm ~ 1569 nm) with excellent spectral flatness2 dB. Output is available via single-mode fiber or polarization-maintaining fiber, with continuously adjustable output power. For PM fiber output, linear polarization can be provided. Suitable for applications such as optical fiber sensing, and various package options are available.
Product Features
