The 40 Gbps is PON is designed using different modulation formats such as NRZ-OOK, RZ-OOK, RZ-DPSK, and RZ-DQPSK for 20 km distance using TDMA and OCDMA with zero dispersion at BER less than 10 -3 [23].

Global market forecasts predicted that by 2020, more than 26 billion internet devices and connections universally interconnected will require nearly 3 times the data traffic generated when compared to the year 2015. The increase in data traffic, demands for enormous bandwidth capacity. The potential to deliver 10 Gbps of huge data to individual businesses and households will be of paramount importance and a challenging issue for the present day service providers. An intensive study is carried out for the Fiber-To-The-Home Passive Optical Network (FTTH PON) for their use in the optical communication, due to their high data rates and more bandwidth. The current evolution of Next Generation-Passive Optical Networks Stage 2 (NG-PON2) network is the primary key technology for the growing demands of higher bandwidth and transmission of the data to the subscribers present in the access network from the service providers. Time Wavelength Division Multiplexing PON (TWDM-PON) architecture is the viable essential solution for NG-PON2 which provides more bandwidth for bidirectional transmission. This article proposes a design for extended reach TWDM-PON based on reflective semiconductor optical amplifier (RSOA). The exclusive feature of the RSOA is the wavelength conversion, which replaces the transmitters in the subscriber end. The Quality of Service (QoS) performance is critically analyzed for different optical modulation formats in proposed extended reach TWDM-PON using RSOA. The TWDM-PON using RSOA is simulated and investigated for different photodetectors. The analysis is also carried for various distance and data rates. The results exhibited that APD receivers have better performance of minimum bit error rate obtained is 10 -11 and minimum Q factor is 6.2 when compared with PiN receivers. The comparative analysis of different modulation formats shows that the Carrier Suppressed Return to Zero-Differential Phase Shift Keying (CSRZ-DPSK) gives the best performance for longer distance and large data rates and Return to Zero(RZ) gives the least performance.

“…However, RZ-DPSK and CSRZ-DPSK achieve the same bit error rate (BER) with smaller receiver sensitivity [7]. Authors in [8] present that in 16 channel 40 Gbit/s TDMA-PON NRZ-OOK show slightly longer reach with the same BER than NRZ-DPSK. On the contrary, in [9] after transmission with 40 Gbit/s over 12 km standard single mode fiber (SSMF) RZ-DPSK and NRZ-DPSK demonstrated higher value of Q-factor than NRZ-OOK, but DB showed significantly better result.…”

In this paper we are investigating the performance of different optical modulation formats in WDM-PON transmission system. On-off keying non-return-to-zero (NRZ-OOK), NRZ differential phase shift keying (NRZ DPSK), return-to-zero DPSK (RZ-DPSK, carrier-suppressed RZ DPSK (CSRZ-DPSK) and duobinary (DB) are reviewed. The diversity of different broadband services offered to internet users today, causes growing of individual user demands to internet traffic. To satisfy these demands, capability of access network has to be increased. That is why the problem of increasing data capacity of access networks is actual for implementers of data transmission networks. Since WDM-PON is one of new and promising solutions for access networks, we are investigating it in this research. In its turn, the choice of right modulation format is one of the ways to increase a capacity of transmission network. We use maximal achievable reach demonstrated by each optical modulation format for performance evaluation. To determine maximal reach, we investigate the longest distance, which allows providing data transmission with bit error rate (BER) less than 10 −9 for each modulation format. Our simulated WDM-PON system is 64 channel transmission system with 40 Gb/s speed, that corresponds to the requirements for next generation PON2 (NG-PON2). Our transmission system is based on arrayed waveguide grating (AWG) multiplexers and demultiplexers. We use dispersion compensating fiber (DCF) to improve signal quality. The simulations are implemented using OptSim 5.2 software. As a result, we figure out the modulation formats, which are able to provide maximal transmission distance in such way of WDM-PON system. In addition, we are comparing modulation formats in terms of BER simulating transmission over 40 km fiber span, according to NG-PON2 requirements.

The optical switching crosstalk is the important considerable issue in the optical fiber communication system, it tends to the signal distortion and decreasing of the system performance. This dissertation research is proposed a guideline to design a flexible fiber to the x (FTTx) system based on wavelength division multiplexing passive optical network (WDM-PON) combining with wavelength selective switches (WSSs). For the system configuration, the 4 wavelengths-10 ONUs system with the data bit rate of 10-Gbps/? and 40-Gbps/ ? are studied in this dissertation. Moreover, to be active switching, the dynamic wavelength bandwidth allocation (DWBA) controller is used to control WSSs. The modulation format NRZ-OOK is applied for 10 Gbps/? system and the advanced modulation format NRZ-DQPSK is applied for 40 Gbps/? system. The investigation of this dissertation is mainly focus on the improvement of system performance such as the minimum received optical power and power budget related with bit error rate(BER). In order to improve the system performance, the signal distortion reduction methodology is applied by adding the proper delay times in switching characteristics of 3 different types of WSS. The results of investigation come from only the computer simulation by using the commercial OptiSystem software without performing real experiments. The maximum reach of data transmission is limited to 20 km over ITU-T G652.D SMF fiber with the limited BER=10?? (without using forward error correction: FEC). As the results based on worst case BER, the received optical power for both system designs are improved after providing proper delay times in switching characteristics of WSS. Obviously, the power budget is improved by about 3 dB after providing 3? delay time of electro-optic switch for both system designs.
