Abstract :
In this paper the optimal allocation of fiber Bragg grating (FBG) as a dispersion compensator in the presence of group velocity dispersion (GVD) and third-order dispersion (TOD) has been examined. The optimization is performed by varying the compensator arrangements and span length. Four different arrangements are considered-pre-configuration, post-configuration, mid-configuration and bi-end configuration. Span length is varied from 30 to 120 km. At the receiver, Q-factor and bit error rate (BER) have been systematically compared for standard single mode fiber (SSMF) and non-zero dispersion-shifted fiber (NZDSF). The results show that NZDSF based long-haul lightwave communication system with mid compensated scheme provides better performance at 160-Gb/s.
