“…We simulate both variants for comparison purposes. Results in [6] show that DB offers the lowest BER compared to NRZ, RZ, Chirped RZ, CSRZ, NRZ-DPSK and RZ-DPSK in WDM-PON networks with channel spacing 100 GHz and bit rates 1.25 Gbps, 2.5 Gbps and 10 Gbps. Another important format we investigate is DQPSK, implemented in NRZ, RZ and CSRZ formats.…”

In this paper we focus on modulation formats for optical transmission networks. The most widely used intensity formats such as Non Return to Zero, Return to Zero, Carrier-Suppressed Return to Zero and duobinary are investigated in terms of bit error rate, Q-factor, optical reach and dense wavelength division multiplexing grid, in order to find out their physical limitations and system performance in a transmission system with given parameters. However, phase-based modulation formats like Differential Phase-Shift Keying and Differential Quadrature Phase-Shift Keying can perform better at the cost of increased transceiver's complexity. Some formats can benefit from polarization division multiplexing to enable higher spectral efficiency, optical reaches, optical to signal noise ratio and chromatic dispersion tolerances. Simulations are performed in OptSim software environment based on the Time Domain Split Step method which uses full band simulation and offers aliasing errors immunity, accurate differential group delays, parallel computing, etc.

“…In order to increase the data rates of passive optical networks, advanced modulation formats have been proposed and implemented to decrease the effect of non-linearity's and dispersion effects [6]. Several modulation formats have been proposed by researchers in downstream and upstream such as NRZ, RZ, MD-RZ [7], CSRZ, MDRZ, DPSK [8], RZ-DQPSK/OOK [9], Differential Phase Shift Keying (DPSK)/OOK [9], Carrier suppressed return to zero CSRZ-DQPSK/OOK [9][10][11], NRZ-DQPSK/ASK [12,13], DPSK/ IRZ [14,15]. But either above modulation techniques has been implemented over 10Gbps only (i.e.…”

“…In comparison with NRZ-DPSK, RZ-DPSK show better performance. Authors in [11] compare NRZ, RZ, CRZ, CSRZ, DB, NRZ-DPSK and RZ-DPSK and the best performance is shown by DB and good results are also demonstrated by NRZ-DPSK. These results are obtained for 8-channel WDM-PON with transmission over 50 km long fiber span.…”

“…According to [11] till lately, the dominant optical modulation format in the optical transmission system was non-return-to-zero (NRZ) on-off keying OOK with direct detection (DD); however, demand on higher data rates, better system reliability and optimal working conditions motivated many studies in this field.…”

Considering the growing demand for broadband of access networks, in the present paper we investigate 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 (NRZDPSK), 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 the transmission system without dispersion compensation the best results 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.
