Abstract :
In a broadband signal transmission through an optical fiber, the propagation speed depends on the wavelength due to chromatic dispersion caused by external disturbances. Chromatic dispersion distorts the broadband signal. A wide-bandwidth, more than 1 THz, chromatic dispersion measurement method using two optical combs having slightly different frequency spacing has been developed.
