This study has outlined the effects of physical parameters of erbium doped fiber amplifier (EDFA), semiconductor optical amplifier (SOA) on the performance of amplified soliton transmission systems. Injection current-based SOA, EDFA length is taken into account. It is observed that the optimum soliton power and signal per noise ratio are achieved with 5 m EDFA length and 900 mA injection current-based SOA. As well as the bit sequence variations based user defined bit sequence generator are employed in order to measure the soliton transmission system performance. The signal per noise ratio is enhanced with 4 bit sequence. Soliton peak power, output soliton power, and maximum Q-factor are optimized with 8 bit sequence for soliton propagation length of 150 km and possible transmission data rates of 160 Gb/s. Improvement percentage ratio in soliton peak power by using two amplification techniques a long propagation length is deeply stimulated with optiwave simulation program.

This paper has presented the basic infrastructure of different multilayer graded index fiber profiles design. The optimum graded refractive index fiber profile design for the control of total Losses and dispersion effects are considered. The trade-off between different refractive index fiber profiles is realized in order to achieve loss and dispersion effects management. It is evident that the proposed first optical fiber has presented lower dispersion and splice loss than other proposed fibers. As well as the proposed third optical fiber outlines lower effective mode field diameter and micro bending loss than other proposed fibers. Dominant mode, cutoff wavelength and international telecommunication union-telecommunication (ITU-T) values for each fiber are examined based on finite difference method.

This paper has presented the simulation of single fiber Bragg grating (FBG) characteristics using Optigrating simulation software at the worst case. Various types of the same/different refractive index grating/fiber profiles are employed in order to test the transmittivity/reflectivity, bandwidth, and average group delay ripple factor level measurement of single FBG with optimum case. As well as output pulse intensity spectrum is examined for each case. It is observed that minimum side lobes strength, maximum output pulse intensity spectrum, dominant mode, narrow spectral bandwidth, maximum transmittivity/reflectivity spectral response are achieved with grating (exponential)/core (exponential)/region 1 (Gaussian cladding) FBG profile configuration, and grating (exponential)/core (parabolic)/region 1 (Gaussian cladding) profile configuration. Optigrating simulation results give an idea about the efficiency of the suggested hybrid FBG refractive index profiles to analyze FBG technical characteristics.
