AbstractIn this paper we will study the various method of dispersion compensation in single mode fiber created because of dependence of group index to wavelength known as chromatic dispersion. Various methods of dispersion compensation are Dispersion compensation fiber (DCF) which compensates dispersion at 1310nm and 1550 nm and Fiber Bragg gratings (FBG) which compensate dispersion at waveleng...

Fiber-optic communication systems are light wave systems that employ optical fibers for information transmission to increase several orders of magnitude the bit rate distance product. However the performance of optical fiber communication system is limited by fiber dispersion. Dispersion compensation is the most important and challenging aspect of the optical fiber communication to maintain a h...

With the development of high-speed, longdistance optical fiber communication systems, single-mode fiber polarization mode dispersion (PMD: Polarization mode dispersion) becomes one of the important factor limiting high-speed, long-distance optical fiber transmission. Polarization mode dispersion can cause pulse broadening in thedigital transmission system, result inter-symbol interference in di...

Chromatic dispersion profile of dual-concentric-core photonic crystal fibers is optimized for broadband dispersion compensation of single mode fibers (SMFs) by using genetic algorithm incorporated with full-vector finite-element method. From the numerical results presented here, it is found that by increasing the distance between central core and outer ring core, larger negative dispersion coef...

In long-haul wavelength-division-multiplexed (WDM) transmission systems, signals with shorter and longer wavelengths have self-phase modulation group-velocitydispersion (SPM-GVD) penalty caused by to the dispersion slope even after the dispersion-compensation at the receiver has been optimized. As a countermeasure, we have already proposed both pre-compensation and post-compensation of chromati...

An exploration in the competency of the optical multilevel Mapping Multiplexing Technique (MMT) system in tolerating to the impact of nonlinearities as Self Phase Modulation (SPM) during the presence of dispersion compensation methods. The existence of high energy pulses stimulates deterioration in the chirp compression process attained by SPM which introduces an upper power boundary limit. An ...

-In modern optical fiber communication systems, dispersion and nonlinear effect of optical fiber are the two main factors of decreasing communication quality, especially in Group Velocity Dispersion (GVD). In this paper, we use single-mode transmission fiber, Dispersion Compensation Fiber (DCF) and erbium-doped fiber amplifier (EDFA) to design a dispersion compensation optical fiber communicati...
