Abstract

Recently, researchers have focused a substantial amount of their attention on newlinethe design of Dense Wavelength Division Multiplexing (DWDM) optical newlinetransmission systems for high-speed data communication. The designing of DWDM newlineoptical transmission systems plays a very important role in the development of newlinemodern optical communication systems. Long-haul optical transmission systems are newlinewithin the scope of capability for DWDM optical systems. Because of the newlinecharacteristics of the system, the DWDM design for long-distance optical newlinecommunication faces a number of difficult challenges, including dispersion and newlineattenuation. The primary needs for optical communication systems are a good newlineQuality-factor (Q-factor), a low Bit Error Rate (BER), and a better eye opening. newlineThe design, modeling, and performance analysis of DWDM optical newlinetransmission systems for long-haul communication systems are the primary topics of newlinethis thesis. Extensive research is conducted on four distinct DWDM optical models newlineby utilizing a variety of dispersion correction strategies. These include a 16×10 newlineGbps DWDM optical model utilizing dispersion compensation fiber (DCF) newlinetechniques, an 8×10 Gbps DWDM optical model utilizing linear chirped fiber bragg newlinegrating (LcFBG) and dispersion compensation fiber (DCF) techniques, a method to newlinecalculate the pulse width reduction percentage (PWRP) for 300km optical newlinetransmission systems utilizing a variety of chirped fiber bragg grating (CFBG), DCF newlineand hybrid DCF+FBG techniques and a 32×40 Gbps DWDM optical model using newlinedifferent hybrid dispersion compensation techniques such as DCF, DCF-FBG, newlineoptical phase conjugation-dispersion compensation fiber (OPC-DCF) and OPC- newlineDCF-FBG. In this study, the development procedures of specified DWDM optical newlinetransmission models are explored in depth in order to get an understanding of their newlinehigh Q-factor and minimal BER performance. newline
