Abstract
We present a new simultaneous differential phase-shift keying (DPSK) payload and subcarrier-multiplexed (SCM) label generation technique using a single dual-electrode Mach-Zehnder modulator (DE-MZM). We conduct simulations to verify the feasibility of the new SCM labeling scheme and examine the mutual interference between the DPSK payload and the SCM label. By selecting the subcarrier at half of the payload bit-rate frequency, we can significantly suppress the SCM label induced-power penalty to the DPSK payload. Moreover, we apply the SCM label generated by the proposed labeling technique to chromatic dispersion monitoring for DPSK systems. Simulation results show that by detecting radio frequency power of both the clock tone and the SCM label, the monitoring range is greatly improved.
