Analysis and suppression of intermodulation distortion effects in mach - zehnder modulator for analog optical transmission systems

Shahidul Islam, Md. (Institute of Information and Communication Technology (IICT), 2010-03)

The Mach-Zehnder (MZ) interferometer has been extensively used as an electro-optic modulator to overcome the limitations of frequency chirping, phase noise and nonlinearity of intensity modulation in analog radio frequency ...
Analysis of cross phase modulation with first-and second order GVD in WDM of fiber optic communication system

Nasrin Sultana (Institute of Information and Communication Technology (IICT), 2014-02)

With increased channel capacity, launched optical powers, bit rates and number of wavelength channels, the cross phase modulation (XPM) has become the most important nonlinear effect and limits system performance. On the ...
Comprehensive model for studying the suppression of four wave mixing in WDM optical transmission system

Shamim Al Mamun (Institute of Information and Communication Technology (IICT), 2012-03)

Fiber nonlinearity can cause interactions and severe crosstalk among co-propagating wavelength division multiplexing (WDM) channels in high capacity optical fiber communication system. The crosstalk between channels leads ...
Cross-talk analysis of limited wavelength interchanging cross-connects (L-WIXC) in a WDM network

Kundu, Punab Chandra (2011-06)

Limited Wavelength interchanging crossconnect (L-WIXC) is an essential element in a WDM optical network which not only selects the route to be followed but also selects the wavelength to be used along the selected route ...
Effect of stress on propagation properties of PCF with different design parameters

Rokeya Khatun, Mst. (Institute of Information and Communication Technology (IICT), 2012-02)

Optical fiber based wavelength division multiplexing (WDM) is widely used to satisfy the high bandwidth demand using optical network. But dispersion, non-linearity and attenuation restrict the wavelength region and ...
Effect of XPM and FWM on the performance of M-ary WSK-DWDM transmission system

Jahangir AlaIn Majum~~r, A.K.M. (Department of Electrical and Electronic Engineering, 2008-04)

Optical dense wavelength division multiplexing (DWDM) systems using low dispersion fibers and erbium-doped fiber amplifier (EDFA) are very attractive to meet up the growing demand for broadband information distribution ...
Minimization of the effect of cross phase modulation on a WDM optical transmission system

Abu Taher, Kazi (Department of Electrical and Electronic Engineering, 2005-08)

Cross phase modulation (XPM) is the most serious effect that limits the allowable input power and system capacity by generating intensity modulated power causing more noise at the receiver in long-haul multichannel light-wave ...
New approach of channel allocation technique to suppress four wave mixing

Ayesha Rouf (Institute of Information and Communication Technology (IICT), 2013-02)

Four wave mixing (FWM) nonlinear crosstalk degrades the performance of Wavelength Division Multiplexing (WDM) transmission system significantly. Characteristics of FWM are closely related to frequency allocations of channels. ...
