Performance Assessment of Dispersion Compensation Using Fiber Bragg Grating and Dispersion Compensation Fiber Technique

The demand for data transmission is rising expensively for the applications of biomedical sensors data, multimedia technologies, and ultrahigh-definition online video streaming. Such applications require larger bandwidth with minimum latency and seamless service delivery. Radio-over-fiber (RoF), integrated with wavelength division multiplexing (WDM) technology, is being considered one of the promising technologies. However, the integration of optical fiber and wireless communication also generates non-linear effects as and when the number of users increases. That results in the introduction of signal noise, unwanted frequencies, low quality of signals, and increased latency. In this paper, a 16-channel 160 Gbps data rate WDM-based RoF system has been simulated and evaluated for optimum performance at a variable input power level, from 5 to −15 dBm, with the application of dispersion compensation fiber (DCF) and fiber Bragg grating (FBG), with channel spacing of 50 and 100 GHz. The performance of the system is evaluated with the existing WDM-RoF system. The performance metrics parameters chosen for evaluation are bit error rate (BER), quality factor (Q-factor), and eye diagrams and simulated on opti-system simulator. The optimum performance has been observed at a power level of −5 dBm for all these elected evaluation parameters. It has also been observed that, for channel spacing of 100 GHz, the network performed better in comparison with 50 GHz.

Dispersion Compensation Fiber

The growth of optical systems is stimulated for high channel capacity and high bandwidth to meet the explosive development in data communication. Most of the voice and data traffic is transmitted through optical fiber link in these days. In order to share the large bandwidth of optical fiber by multiple channels of different wavelength with higher data rate WDM networks are used. The performance WDM networks are highly effected by the nonlinear dispersion which needs to be managed. In this paper the performance of WDM optical network is analyzed by using Dispersion compensation fiber, fiber bragg grating, and polarization controller. It has been concluded from the results that the use of polarization controller provides the high quality output as compare to Dispersion compensation fiber, fiber bragg grating for each channel.

Dispersion Compensation Fiber

In this paper, a proposal for analyzing the performance of an optical system by using dispersion compensation fiber (DCF) and linear chirped apodized fiber Bragg grating (FBG) has been put forth. Both systems have three different schemes pre, post and symmetrical. Various parameters used for this analysis are input power, distance & input bit rate. Performance is analyzed in terms of Q factor, Bit Error Rate (BER) and Eye Diagram. It is found that use of FBG as a dispersion compensating element gives better system performance as compared to DCF.
