High Bandwidth

Optical Fiber Communication System is highly in demand because of several advantages namely Extremely High Bandwidth, Longer Distance, Low security Risk, Small Size etc. This system basically consists of Optical Transmitter, appropriate channel and Optical Receiver. Optical Fiber is generally used for the propagation of optical signals and in this fiber, Dispersion arises which acts as the main hindrance in Optical Fiber Communication. Dispersion is nothing but the time broadening of pulses because of the inherit property of the Silica Fiber that refractive index of the material depends upon the wavelength used. In this paper, Compensation of Dispersion is done using the FBG(Fiber Bragg Grating. FBG is a type of filter which passes few wavelengths and reflects rest of them. Stimulation is done on software named OPTISYSTEM 15. Simulation results are analyzed through Eye Diagram which gave us the values of MIN.BER and Q-Factor.

Transmission Speed

The discovery of optical fiber cause widespread revolution of communication system. Optical fiber communication has excellency on data transmission speed, security, flexibility, and broadly bandwidth. The applying of WDM network can broaden the bandwidth so that the transmission performance becomes more splendid. Although some factors such as dispersion, attenuation, and scattering can hinder the performance of fiber optic on sending data. Moreover dispersion can wreck data and spread pulse as it travels alongs fiber so that causing interference. There is some methods  of dispersion compensation. In this paper, Fiber Raman Amplifier is used on WDM network to strengthen signal which is sent to detector. This research utilize simulation approachment  with various bandwidth and length fiber. The results show lowest BER value and highest Q-factor at bandwidth frequency of 30 GHz and fiber length of 20 km.

Communications System

For high bit-rate optical communications system, the changes in temperature or power fluctuations are due to the dispersion of the dispersion tolerance than the system. Therefore, the dispersion compensation unit must have the functionality to adapt to the dynamic generation of tunable optical communication network development. This article describes several dynamic tunable compensation techniques and the basic principles of the performance characteristics of the situation at home and abroad, including the chirped fiber grating method, the virtual image phased array method, GT interferometer method, the array method and the planar waveguide grating method, and a brief discussion of tunable dispersion compensation technology in the future direction of development.

AbstractApplication of fiber Bragg grating (FBG) in optical communication is an evolving field. In this research paper, various types of chirped FBG’s (CFBG) have been used with avalanche photodiode (APD) on the designed optical fiber communication (OFC) link. Data rate of 20 Gbps and return-to-zero modulation format has been kept as fixed parameters. The designed link has been evaluated for varying fiber lengths (100, 200, 300, 400 and 500 km), various type of CFBG’s (linear, quadratic, square root and cubic root) with Gaussian apodization function, varying grating lengths (10, 20, 30, 40 and 50 mm) and operating temperatures (5°C, 10°C, 15°C, 20°C, 25°C, 30°C). The designed OFC link has also been evaluated for APD with and without CFBG. The performance evaluation matrix parameters selected are Q-factor, bit error rate and eye diagram. The OFC link employing CFBG with APD has been found to be superior. In compensating chromatic dispersion, optimum results have been observed for linear CFBG with Gaussian apodization function in comparison to other types of CFBG with 50 mm grating length for the maximum transmission distance.
