Abstract :
We analyzed 10 GHz NRZ-DPSK signals´ PM-AM conversion process and demonstrated chromatic dispersion (CD) and OSNR monitoring simultaneously based on measuring 010 GHz RF spectrum power of the PRBS signals. The monitoring range of CD and OSNR are up to 4320 ps/nm and 10-30 dB respectively.
