Abstract Pulse spreading due to the dispersion causes the overlapping of the transmitted
pulses at the receiver end known as inter symbol interference (ISI). The ISI thus limits
transmission of high speed data. We are living in the age of bandwidth hungry and high
speed applications, for which optical networks form the most important part because of its
high bandwidth. In optical networks chromatic dispersion (CD) is one of the main obstacle
in high speed transmission. Hence this CD is compensated by various approaches
throughout the transmission system. A review of all the main approaches is presented in
this paper. Characterization of fiber Bragg grating for dispersion compensation is done
using the reflection spectrum and group delay response analysis.
