We simulated different modulation formats in optical fiber systems in the presence of polarization mode dispersion (PMD) and fiber nonlinearities. Non-return-to-zero (NRZ), return-to-zero (RZ), chirped RZ (CRZ), carrier suppressed RZ (CSRZ), duobinary, differential phase shift keying (DPSK), differential quadrature phase shift keying (DQPSK) and CSRZ-DQPSK formats are simulated. The maximum data rate...
We simulated two multilevel modulation formats in optical fiber systems in the presence of varying polarization mode dispersion (PMD) and fiber nonlinearities. Carrier suppressed return-to-zero differential quadrature phase shift keying (CSRZ-DQPSK) and polarization shift keying (PolSK) formats are simulated. The maximum data rate used in the system is 92 Gb/s and the length of the fiber is kept fixed...
