“…The core region of this compensating fiber is highly doped, which results in negative https:// journal.uob.edu.bh dispersion effects. The negative dispersion range of this fiber is defined as-70 to-90 ps/nm [1]. The performance of the optical WDM system design can degrade due to the accumulation of ASE noise caused by periodic amplification, Kerr nonlinearity, and group velocity dispersion [55].…”

“…SMF with negative dispersion is considered as a Negative DCF. This effect is achieved through a weakly guided mode, in which even a slight variation in the wavelength can cause significant changes in mode size [1]. The difference in the guided mode leads to increased attenuation and Figure 3.…”

“…In order to extent the data carrying capability of an optical communication system WDM is one of the effective technique in optical communication system.WDM permit multiple wavelengths to be transmitted at same time over a single fiber [2].WDM support high bandwidth data transfer. The management of dispersion and non linearity's are main significance in WDM systems [3] The dominant aim of optical fiber communication is to expand the transmission distance [4]. The main factors that influence the WDM system are loss, dispersion , and non-linear effects like Self Phase Modulation (SPM) , cross phase modulation(XPM) and Four Wave Mixing (FWM) is observed at different data rates [5].So this dispersion and fiber non-linearity's effects at different data rates must be reduced by various dispersion compensation techniques like Fiber Bragg Grating (FBG) [6] Optical Phase Conjugation(OPC) [7] , Reverse Dispersion Fiber (RDF) [8] , Electronic Dispersion Compensation [9] , Dispersion Compensating Fiber (DCF) [10].In order to reduce the impairments due to fiber non-linearity's optical amplifiers such as Erbium Doped Fiber Amplifier (EDFA),Raman amplifier, SOA are also used [11].The use of DCF is effective way to minimize the complete dispersion in WDM network as they have higher negative dispersion coefficient and can be attached to the transmission fiber having positive dispersion coefficient so that the complete dispersion of the link becomes zero.…”
