Basic knowledge of fiber optic cable 45
Introduction: The nonlinear effect will cause additional loss and interference, deterioration of system performance. WDM high power optical system and optical fiber transmission along the long distance, therefore produce nonlinear distortion. Nonlinear distortion has stimulated scattering and nonlinear refractive index of two. 1 Introduction Optical fiber The composition. Answer: the fiber consists of two basic […]
