Chromatic dispersion compensation based on chirped fiber Bragg grating

In this paper, a chirped fiber Bragg grating (CFBG) has been designed for a long-haul communication system in order to compensate its chromatic dispersion. First of all, a complete transceiver has been utilized and designed for testing the effect of the presence of linear chirped fiber Bragg grating in such system. Moreover, quality factor Q-factor and bit error rate BER have been estimated in both case studies; without and with the FBG. Our case study has been developed according to a fiber cable with length 100 KM with a grating length of only 10 cm. Experimental results show that quality factor has been enhanced from 2.6 dB to 27.14 dB. Accordingly, bit error rate has been decreased from 0.0038 to 1.49e-162. Those results guarantee the effectiveness of the FBG with long fiber cables.
