Multiple optical soliton solutions for wave propagation in nonlinear low-pass electrical transmission lines under analytical approach

The nonlinear low-pass electrical transmission line equation under investigation base on analytical approach named extended modified rational expansion method. The NLETLs equation play important role in electronic engineering and communication system included connection system of computer network, signal distribution of cable television, high speed computer data buses, truck lines of routing calls in switching centers of telephone, connection between radio transmitter and receiver and its antennas and so on. In this study, we constructed multiple solitary wave solutions included anti-kink solitons, periodic solitary waves, dark silotons, kink solitons, bright solitons, singular bright, singular dark, combined bright-dark and combined dark-bright solitons under symbolic computation. The physical phenomena of calculated solutions represent graphically in contour, two and three dimensional. The all calculation prove that our proposed approach is powerful, efficient and can also usable for the investigation of other nonlinear equations.
