“…In this paper, a new apodization function is used by the author, but the performance of the system is not good with reference to the Q-factor. Sayed et al [28] suggested a model using symmetrical and post dispersion compensation techniques. Performance is evaluated with reference to the Q-factor and BER and performance is increased by 21% for symmetrical dispersion compensation approach and 19% for post dispersion compensation approach compared to earlier done work.…”

Further, DCF and FBG techniques are reported to conflict the dispersion or PWB in optical fiber transmission system (OFTS) by selecting the different location as pre, post, and symmetric compensation [1113]. The comparative analysis for different long-haul optical transmission system has also been designed through DCF and FBGs techniques. It has been observed that the DCF and FBG give good performance [10]. Furthermore, comparative analysis of different hybridizationdispersion-compensation techniques like chirped fiber Bragg grating (CFBGs), DCF+FBG, optical phase conjugation (OPC) +DCF, FBG+DCF+OPC are available in the literature. These techniques overcome the dispersion phenomena, but the cost of system increases [1, 5, 1420]. According to the literature [1120], most of the investigations emphasize on DCF, FBG, OPC+DCF and DCF+FBG techniques as dispersion compensator, but the cost of implementation is still high and challengeable. It is also observed that the performance of OFTS system

“…A WDM technology practically gives attractive properties as reducing number of fibers, low attenuation, small signal power, higher bandwidth, reduced signal distortion, and small space equipment. Irrespective of all previous WDM properties, many unwanted factors in the optical fiber reduce WDM performance as attenuation, dispersion, and nonlinear effects (Sayed et al 2021).…”

The backward Raman amplifier (RA) can considered as one of the best solutions for optical communication, especially in Wavelength Division Multiplexing (WDM) technology. They reduce the nonlinear effects, have low noise figure and a wide frequency range. The work in this paper aims to reduce the attenuation of optical signal due to its propagation optical fiber and increase both amplifier gain and output signal power. Two backward Raman models are proposed. Proposal one model consists of two cascaded RAs and the other (proposal two) consists of three cascaded RAs. Three backward pump power levels 200, 400, and 600 mW are used to simulate the models with the three types of fibers: single-mode fiber (SMF), Truewave, and Freelight, at an amplifier length of 100 km. Proposal two achieves a maximum gain of 31 dB at 600 mW pump power 600 mW using Truewave optical fiber, with 27.7 dBm maximum output signal power. This proposal is evaluated showing 11.15% gain enhancement and 200 mW saved power when compared to previously published work.
