“…The performance investigation of a four channel DWDM system employing the NRZ and RZ modulation schemes with an 8 Gbps bit rate revealed values for the post compensation technique's q-factor and BER for both modulation schemes, with the NRZ modulation strategy yielding unsatisfactory results in this work (4,5) . Using NRZ rather than RZ, Performance Analysis of OWC system-based (S-2-S) connections yields much superior results for the full lengths tested.…”

Objectives: This study aims to enhance and optimize a modern communication system for high data rate transmission using Dense Wavelength Division Multiplexing (DWDM). The objectives include employing a 64-channel DWDM system, implementing different data speeds, and utilizing a dispersion compensation method. Methods: To achieve the objectives, we simulate and analyze the effects of Dispersion Compensation Fiber (DCF) in a DWDM system with 64 channels. The system employs Non-Return-to-Zero (NRZ) modulation format at varied bit rates and multiple energy levels. We propose a method for achieving data rates of 10 to 40 Gbps using NRZ modulation and Erbium-Doped Fiber Amplifier (EDFA) over a single-mode fiber transmission distance of 40 to 160 km, along with a dispersion compensation fiber of 8 to 32 km (DCF). The performance of the developed model is evaluated based on Quality Factor, Bit Error Rate (BER), Eye Height, and Threshold. These metrics are measured at two input energy levels from an optical power source, covering a communication capacity ranging from 0.625 Tbps to 2.5 Tbps. Findings: Through the simulations and analyses, we uncover the impact of dispersion and demonstrate the effectiveness of the proposed method in compensating for dispersion effects. Performance analysis of two different input transmitter power levels, -10 dBm is more efficient compared to 0 dBm input transmitter power in terms of bit error rate and quality factor. Novelty: This study presents a novel approach to improving modern communication systems by utilizing DWDM with a dispersion compensation method. The use of a 64-channel DWDM system, combined with the proposed NRZ modulation technique and dispersion compensation fiber, provides an efficient solution for achieving high data rates over long transmission distances while minimizing the effects of dispersion. The findings contribute to the advancement of communication systems for high data rate transmission.

This work is proposed to examine the modified duobinary modulation scheme in a fast DWDM framework. In this work, the system is simulated with 32 channels having a limit of 40 Gbps multiplexed with the channel spacing of 80 90 and 100 GHz to perceive 1.2 Tbps complete transmission distance over the optical range of 250 km by utilizing scattering remuneration strategy. The 40 Gbps is encoded by utilizing Mach Zehnder modulator (MRZ) inferred by CW laser of power - 10 dBm, - 5 dBm,0 dBm,5 dBm,10 dBm. In the system analysis, we use modified duobinary return to zero (MDRZ) in the DWDM system. The impacts of a variety of channel dividing on transmission distance are seen as far as Q Factor, absolute power got and changing distance keeping BER in an acceptable range.

Linear and non-linear impairments are the major problems that affected the dense wavelength division multiplexing (DWDM) system performance. In this simulation designs, two different compensation techniques have been proposed to eliminate signal impairments. The repeater technique was proposed to reduce non-linear effects like four-wave mixing (FWM) which cause transfer power from DWDM channels to another new channels. The dispersion compensation fiber (DCF) technique was used to reduce dispersion effects which cause signal pulse broadening over long transmission distances. Also, three different modulation formats and four frequency separations were used to determine which modulation scheme is more compatible with the compensation techniques. The results is calculated in term of quality factor against power and noetic that the carrier suppressed return to zero (CSRZ) format offers the best performance with the DCF technique with 32.1804 Q-factor at 15dBm threshold power then, the differential phase shift keying (DPSK) format is compatible with the repeater technique with 27.7959 quality factor and 14dBm threshold power. Index Terms— Dense Wavelength Division Multiplexing (DWDM), Dispersion Compensation Fiber DCF, Repeater, and Non-linear Effects.
