In this paper, we theoretically and experimentally demonstrated the residual chromatic dispersion (CD) measuring of 10Gbit/s NRZ and 40Gbit/s NRZ/RZ links by using a novel single sideband (SSB) spectrum phase difference detection technology. This method can differentiate positive and negative residual CD of the fiber link, the measuring range is dependent on frequency difference (FD) of two local oscillator (LO) and the FD can be adjusted up to CD range. This method is independent on data rate for intensity modulation direct detection (IM/DD) links. In condition of FD of 4 GHz, the measuring range was around ± 1000 ps/nm and resolution was better than 5 ps/nm for 10G NRZ link.
