Dispersion Compensation Modules 

GAO’s dispersion compensation modules are devices used in optical communication systems to mitigate the effects of dispersion. Dispersion is the spreading of optical signals as they travel through a fiber optic cable, leading to signal distortion and loss of data. Dispersion compensation modules employ specialized techniques, such as dispersion compensation fibers or gratings, to effectively counteract dispersion and maintain signal integrity, allowing for longer transmission distances and higher data rates in optical networks. 

GAO’s dispersion compensation modules are composed of light source, power meter, optical attenuator, polarization controller, dispersion emulator, and optical spectrum analyzer. 

The other common names of dispersion compensation module are dispersion compensation module, DCM, dispersion compensator, signal equalization unit, chromatic dispersion module, optical signal stabilizer, light path equalizer, fiber dispersion correction device, optical transmission equalizer, and signal quality enhancer.
