研究目的
To investigate the impact of major nonlinearities in optical fiber such as Stimulated Raman Scattering (SRS) and Four Wave Mixing (FWM) in cascaded amplifier Dense Wavelength Division Multiplexing (DWDM) optical long reach and high speed data rate transmission scheme at different data rates.
研究成果
The study concludes that system quality degrades with increased data rate per channel and fiber length due to nonlinear factors SRS and FWM. However, using DCF, optical fiber, and EDFA with individual span of fiber improves system performance for data rates of 10, 40, and 100 Gbps over a 600 km path range.
研究不足
The study is limited by the high signal noise contributed by used amplifiers and combined nonlinear effects from transmission, which degrade system performance at high data rates and long distances.
1：Experimental Design and Method Selection:
The study involves mathematical investigations and experimental simulations to analyze the effects of SRS and FWM at data rates of 10, 40, and 100 Gbps.
2：Sample Selection and Data Sources:
The simulation uses a 16-channel DWDM optical network with central frequency
3：1 THz. List of Experimental Equipment and Materials:
1 The setup includes optical dense wavelength division multiplexers, dispersion compensation fiber (DCF), single model fiber (SMF), erbium-doped fiber amplifiers (EDFA), and PIN detectors.
4：Experimental Procedures and Operational Workflow:
The simulation models consist of transmitter, medium, and receiver end, with signals fed to the multiplexer, transmitted through fiber spans, amplified, demultiplexed, and detected.
5：Data Analysis Methods:
The analysis involves assessing signal to noise ratio (OSNR) and Bit Error Rate (BER) with respect to noise inter amplifier separation, transmission length, and inter-channel space.
