Submarine fiber cable network systems cost planning considerations with achieved high transmission capacity and signal quality enhancement

This paper has presented theoretically the comparison between three types of fibers which are investigated extensively: plastic clad silica (PCS), polystyrene (PS) and perfluorinated graded index polymer optical fibers (PF GI-POF) for high speed undersea cable systems. Based on experimental data, both the deep ocean water temperature and pressure are tailored as functions of the water depth. It is taken into account the estimation of the total cost of the submarine fiber cable system for transmission techniques under study. The system capacity as well as the spectral losses, and the dispersion effects are parametrically investigated over wide range ranges of the set of affecting parameters {wavelength, ocean depth (and consequently the ocean pressure and temperature), and the chemical structure}. The results show that PCS has the optimum performance in compared with other fibers. Therefore PCS fiber is the most appropriate candidate among all types of fibers for high speed local submarine communication systems.
