    • 1270nm High stability DFB lightsource     


    The wavelength tuning range of the light source covers C-band and realizes continuous laser output of up to 96 wavelengths (ITU-T standard wavelength, wavelength interval of 50GHz). Integrated with adjustable filter and high gain chip, it has the characteristics of high output optical power, narrow linewidth and high wavelength accuracy. It is equipped with special drive and control circuit, high-definition color LCD screen, and upper computer software. Users can easily tune the wavelength accurately. It can be used in the fields of optical fiber link, DWDM, optical fiber testing, etc.
