A study of chromatic dispersion (CD) in optical fibers, its effects on signal propagation, the devices to compensate it and the methods for its characterization. We have presented the exper- imental setups for the most popular frequency domain methods for CD measurement, Peucheret and Modulation Phase Shift Method (MPSM), as well as for an advanced method with improved performance, the Asymmetric Mode and Bias Control method (AMBC), whose theoretical basis have also been described. Experimental measures of the D parameter of CD for both 75km of standard single-mode fiber and a Dispersion Compensating Fiber Bragg Grating (DC-FBG) with all 3 methods have shown good agreement. 2016/2017
