“…Gnanam Gnanagurunathan et al [5] -Comparing FBG and DCF as dispersion compensators in the long haul narrowband WDM systems‖, in this author presented found that each kinds of dispersion compensators worked as meant, but the FBG compensator outperformed the DCF module for the short haul link, long haul link, traffic load variation and modulation scheme variation analysis on the four channel WDM systems. FBG may be a feasible choice to be looked into for chromatic dispersion compensation compared to DCF for a WDM long haul transmission and additionally long-run network growth purposes.…”

This paper review of the chromatic dispersion compensation in optical fiber communication system. In optical communication system to compensate dispersion Fiber Bragg grating (FBG) is one amongst the applicable and necessary components. During this the appliance of chirped FBG was studied as a dispersion compensator in optical communication systems. This paper studied the various types of simulation in optical fiber communication system. The reviews of the analysis based on the chromatic dispersion are studied in the paper.

“…The subsequent part of the system is the fiber optic channel, which contains three processes: (i) Standard Single Mode Fiber (SMF) using to send optical signal. ; (ii) compensating the dispersion in the optical channel using a Dispersion Compensating Fiber (DCF), where, the DCF, which is treated as a special kind of fiber optic that has a considerable negative dispersion, is used after the standard SMF [11] and (iii) amplifying the strength of signals being carried through the fiber optic channel using an Erbium-Doped Fiber Amplifier (EDFA) as well as compensating the attenuation induced by the optical fiber. The third part of the system is the receiver, which contains a coherent reveal block with laser used as a local oscillator, which is used to convert the optical signal to an RF signal.…”

Orthogonal Frequency Division Multiplexing (OFDM) is a modulation format that has recently attracted lots of consideration interior the long-haul fiber-optic transmission community. The most important advantage of optical OOFDM is its unlimited capability of canceling Inter-Symbol Interference (ISI) caused by Chromatic Dispersion (CD) and Polarization-Mode Dispersion (PMD). Specifically, Coherent OOFDM (CO-OFDM) presents a good and effective modulation method in modern optical communication systems. However, due to its high Peak to Average Power Ratio (PAPR), the performance of CO-OFDM is affected by nonlinear impairments. In this paper, we propose a new joint nonlinear technique; L3-by-3; with a distortion technique; clipping ; that bypass the requirement for the use of any side information (SI) to minimize the high PAPR value of the transmitted signal and consequently improve various fiber nonlinear impacts through PAPR reduction. The simulation results reveal dependable and excellent signal recapture at the receiver and an effectively minimized PAPR level at the sender side.

this paper compares the efficiency of on-off Keying (OOK) modulation formats non-return-to-zero (NRZ) and return-to-zero (RZ) in both electrical and optical chromatic dispersion compensation. While In electrical compensator feed forward-decision feedback equalizer (FFE-DFE) method was applied, Dispersion Compensation Fiber (DCF) was chosen to evaluate the effect of modulation format on them. Transmission distance, subsequently are varied in both systems with mentioned compensation systems to evaluate the Bit Error Rate (BER) regarding to mentioned modulation techniques.
