We propose a CD monitoring technique in coherent systems by measuring the power of an RF tone from the mixing of RZ-OOK signal with a sinusoidally modulated LO laser. Positive and negative dispersion distinction with variable ranges and sensitivity can be obtained by changing the LO modulation frequency.
