This paper presents the use of multi-wavelength solitons (colored solitons) generated by light in a modified add-drop optical filter. It is made by InGaAsP/InP and known as a PANDA ring circuit. The basic digital codes “0” and “1” can be randomly formed by using the dark-bright soliton conversion concept. In this case the high capacity (bit rate) can be generated by nonlinear effects of the two side...
In this paper, we present the system control design via AC line for the security system. The system comprises houses and control node such as center control, node control and home control which are connected as the two levels network called master-slave model. Our system can support the data rate up to 9,600 bits per second with the maximum distance at 1,200 meters. The transmission data are encrypted...
