Keywords wavelength division multiplexing (WDM), modulation formats, non return to zero (NRZ), return to zero (RZ), carrier suppressed RZ (CSRZ), duobinary (DB), NRZ differential phase shift keying (NRZ DPSK), chromatic dispersion (CD) compensation, dispersion compensating fiber (DCF).
Abstract Considering the growing demand for broadband of access networks, in this paper we are investigating various modulation formats as a way of increasing the performance of optical transmission systems. Non-return-to-zero (NRZ) on-off keying, return-to zero (RZ) OOK, carrier suppressed RZ (CSRZ) OOK, duobinary (DB), NRZ differential phase shift keying (NRZ-DPSK), RZ-DPSK and CSRZ-DPSK formats are compared using the maximal achievable reach with bit error rate less than 10-9 as a criterion. Simulations are performed by using OptSim software tool. It is shown that using transmission system without dispersion compensation the best result are shown by Duobinary and CSRZ-OOK modulation formats, but with the system using dispersion compensating fiber (DCF) the longest transmission distance is achieved by RZ-DPSK modulation format. By investigating the influence of channel spacing for best-performed modulation formats, network reach decrease for transmission systems with DCF fiber has been observed due to channel crosstalk.
