The optical signals pass through a number of components such as optical fibers, filters, multiplexers and switches. These components increase the amount of total dispersion. Dispersion or pulse spreading of the optical signals is a problem which limits the bandwidth and length of the information carrying fiber. Therefore, it is important to control and characterize the dispersion. In this work, our target is to find and characterize the wavelength dependence dispersion and to see the effect of fiber Bragg grating (FBG) as a dispersion compensator. A 100 km single mode (SM) fiber optic link...

A robot is a software controlled mechanical device that uses sensors to guide one or more end effectors(such as tools, grippers or hands) which is end of a manipulator, through programmed motions in a work piece in order to manipulate physical objects. This book represents a design process of an industrial robot intends to perform to grip an object and to take it certain place. We have decided to build the robotic arm and base by wood. The special feature of this arm is can pick an object by given instruction and also keep it by given instruction. The aim of this project is to design and...
