“…For higher data rate in PON, different modulation formats have been investigated and analyzed in order to have less nonlinearities and dispersion effects [7]. Different modulation formats have been implemented in 10Gbps data rate such as NRZ, RZ, MD-RZ [8], CSRZ, MDRZ, DPSK [9], RZ-DQPSK with OOK [10], Differential Phase Shift Keying (DPSK) with OOK [11], Carrier suppressed return to zero CSRZ-DQPSK with OOK [10][11][12], NRZ-DQPSK with ASK [13,14], DPSK with IRZ [15,16]. For high data rate, few modulation techniques have been proposed and analyzed such as DQPSK with IRZ [17] and DQPSK with OOK [18].…”

We present a comparison between the two high data rate next generation passive optical network (NG-PON 2) which are feasible to fulfill the future demand for bandwidth hungry applications that exceeds beyond 10Gbps. This paper summarizes the best suitable network for future bandwidth hungry applications by simulating both networks through optisys simulated software considering standard values and recommendations for NG-PON 2. Both networks support 40Gbps with Differential Quadrature Phase Shift Keying (DQPSK) while at upstream one network supports 10Gbps with On Off Keying (OOK) and other support Inverted return to zero (IRZ) with 10Km fiber span. Comparison of both networks transmission performance in terms of BER with Rx power and OSNR has been investigated and results shows that NG-PON 2 support 40Gbps with DQPSK and 10Gbps IRZ is quite better than other network with higher sensitivity and OSNR.

“…Optical fiber communication is a good candidate that can handle a high data rate and forms the backbone of the communications infrastructure. To increase efficiency in optical fiber systems, a Wavelength Division Multiplexing (WDM) is a good choice to achieve it (Chenika, et al, 2014). Modern optical communication systems with high data rate and high capacity depend on advanced modulation techniques with coherent detection and formats that provide high spectral efficiency (Liu et al, 2014, Thuraya andDiana, 2015).…”

In this paper an optical communication system with N-Channel 40 Gb/s Wavelength Division Multiplexing (WDM) has been designed and optimized in the presence of Return-to-Zero Differential Phase Shift Keying (RZ-DPSK), Nonreturn-to-Zero (NRZ), Carrier Suppressed Return-to-Zero (CSRZ) and Modified Duo binary Return-to-Zero (MDRZ) modulation schemes. The system simulation is done using Optisystem simulator version-14 with multiple span Standard Single Mode Fiber (SSMF) transmission and the launched optical power range from (-10dBm to 10dBm). The effect of increase in launched power is studied in terms of Quality factor (Q-Factor), Bit Error Rate (BER), nonlinearity impairments and Eye Opening Penalty (EOP) for different modulation formats. The simulation results show that NRZ has highest Q-Factor of (38) and lowest BER with high nonlinear effects and system performance degradation with the increase of input optical power, while CS-RZ has the lowest Q-Factor of (6) with little nonlinear effect. On the other hand, RZ-DPSK offers high Q-Factor of (32) with high tolerant to nonlinear impairments and the system performance remains resilient to nonlinearity with the increase of input power. It is observed that RZ-DPSK has the lowest EOP that reaches only to 0.7 while NRZ has the highest EOP in which reaches to 4.5. Simulation results also show that RZ-DPSK has higher, wider and clearer eye diagram than other modulation formats. It is concluded that the light wave system with RZ-DPSK format offers the best performance, higher tolerance to nonlinearity and higher dispersion tolerance among other modulation formats.

“…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.…”
