Paper Abstract

Polarization-mode dispersion compensation performance of optical DQPSK is studied in this paper. Firstly, the simulation model for the back to back system of optical DQPSK is established by using Matlab. The optical power spectra and eye diagram of different DQPSK modulation formats are obtained. Then, we adopt two pseudo random binary sequences as input data streams. In the back to back DQPSK system, by means of precoding, modulation and demodulation we obtain exactly the same as the original signal. The system for simulation is verified. At last, we add the polarization-mode dispersion compensation program module to the back to back DQPSK system. The result is shown that the modulation formats with smaller bandwidth have better PMD compensation performance. and that PMD compensation performance of DQPSK is better than that of OOK and DPSK. CSRZDQPSK combines the carrier-suppressed feature of CSRZ formats and specific spectrum characteristic of DQPSK formats, thereby it has the best performance of PMD compensation performance.
