The Consideration of Attenuation and Chromatic Dispersion Parameters to Long-Haul Optical Communication

In long-haul communication, fiber optic cable plays an important role as transmission medium. The C-Band is the typical spectrum used in common optical link implementation, especially for long-range. Generally, dense wavelength division multiplexing (DWDM) uses specific wavelength spectrum based on grid stated in ITU-T G.694.1 recommendation, in which it is proposed to acquire several wavelengths to be used as the channels in the system of DWDM communication-based sensor network. In this paper, C-band DWDM channel determination method is presented. The selected DWDM channels are determined by considering lower attenuation and chromatic dispersion in the G.652.D-based fiber optic from Corning SMF-28 fiber optic technical datasheet towards entire wavelength in C-Band area, thus the optimum channels could be discovered. As conclusion, our research found the attenuation parameter has much more significant effect to Q-factor and BER values compared to the chromatic dispersion effect and the top-five most optimized channels are listed.
