New technique of chromatic dispersion management in optical single-mode binary glass fiber

This paper presents a new technique of chromatic dispersion management in optical single-mode binary glass fiber is introduced to facilitate the design of ultra-wide multiplexing performance in high-speed optical communication systems. The design parameters are: i) the relative refractive index difference of the core and clad, and ii) the percentage of germania doped in silica (binary glass single-mode fiber). The two design parameters are kept within their technological limits of interest. Two ultra wide (UW) multiplexing techniques are simultaneously processed (space division multiplexing (SDM) and wavelength division multiplexing (WDM)). 2400 channels (UWWDM) are transmitted (at the window of optical wavelengths from 1.45 μm up to 1.65 μm) through 140 links (UWSDM), where each link are designed to possess the same squeezed chromatic dispersion. It is found that the link design parameters undergo very weak nonlinear relationships with the number of links. Isothermal surfaces (three dimensional) are investigated. These surfaces relate the desired squeezed chromatic dispersion, the relative refractive index difference, the percentage of doped-germania in silica, and the suboptical window central wavelength.
