Abstract

In this paper, the performance of negative dispersion fiber used as a dispersion compensating module is investigated. The optimal operating condition of the DCM was obtained by considering dispersion management configurations i.e. post-compensation. The DCF was tested on a single span, single channel system operating at a speed of 10 Gbit/s with the transmitting wavelength of 1550 nm, over 120 km of convention single mode fibre. Furthermore, the performance of the system at 240 km,480km,720km,960km,1200km were also used to examine the results for the over- and under compensation links respectively. So far, most investigations for SMF transmission at high amplifier spacings in the order of 90 km to 120 km focused on conventional NRZ-format. The Q-factor and BER was estimated. The results indicate performance for all the configurations.
