This article presents the comparison of approximate and exact small-signal theories for analyzing the in uence of the higher-order dispersion terms on dispersive optical communication systems operating near zero dispersion wavelength for linear singlemode ber. For the approximate theory, the generalized conversion matrix has been reported and gives the transfer function of intensity and phase from the ber input to ber output for a laser source including the in uence of any higher-order dispersion term. In addition, expressions for the small-signal frequency response and the relative intensity noise (RIN) response of an ultrafast laser diode including noises are derived. However, it is observed that the approximation assumed for the second-order dispersion term for the approximate analysis is not valid. From the approximate theory, the exact generalized conversion matrix and exact expressions for small-signal frequency response and relative intensity noise (RIN) are obtained. We show that for the exact theory, the second-order dispersion term has no effect on intensity and frequency response even at large modulating frequencies and large propagation distances contrary to the approximate theory as reported by other authors. But we show that third-order dispersion term certainly has some minute impact on the frequency and RIN response for long distance links at high modulating frequencies.

In this paper, the XPM-induced crosstalk has been evaluated with third order Dispersion in SCM-WDM optical communication system at different optical powers for various parameters (dispersion, transmission length, effective area and modulation frequency) that play an important role in signal transmission. Results show that as the dispersion, transmission length and modulation frequency parameters increase, crosstalk increases with increase in optical powers and effective areas increase, crosstalk decreases with increase in optical power. General TermsXPM-induced Crosstalk, Dispersion, SCM-WDM.

“…Several techniques have been proposed which can be used to overcome power penalty caused due to non linear effects and chromatic dispersion. These include differential delay methods [4], initial pre-chirp [5], dispersion compensating devices [6], mid spam spectral inversion [7][8][9], dispersion supported transmission [10][11][12][13], optical phase conjugation [14][15][16][17][18]. The use of dispersion compensated fiber (DCF) is considered as the best method to mitigate harmful results of dispersion and also to upgrade single mode fiber links which had already been installed.…”

Dispersion is the most important factor which determines the data rate and the maximum repeater distance spacing in a fiber optical link. In this paper, investigation has been done on performance of Fiber Bragg Grating as a technique to compensate chromatic dispersion in a 100 km long fiber optic link using different modulation formats such as RZ and NRZ modulation formats and different values of transmission power levels. It was observed that RZ modulation format showed a better performance with a maximum value of Qfactor of 54.5192 than NRZ modulation format which obtained maximum Q-factor value of 31.4792.
