DK Photonics C-band Wavelength Tunable ASE Light Source, with a wavelength adjustment resolution of less than 0.1nm and a wavelength adjustable range of up to 40nm, can fully cover the C-band spectrum from 1528nm to 1569nm. Output through single-mode fiber coupling, and the output light can maintain an extremely low polarization degree of PER<0.1dB; Alternatively, polarization maintaining fiber output can be chosen, with the output light maintaining a high polarization degree of PER ≥ 23dB. The output optical power is continuously adjustable. Suitable for high-precision measurement of fiber optic devices, providing desktop packaging.
