Ultra High Transmission Capacity of Undersea Optical Fiber Cables for Upgrading UW-WDM Submarine Systems

This paper has proposed ultimate optical transmission of ultra multi transmission channels huge submarine cables has been investigated under different depth conditions. Conventional forward Raman amplification technique is considered taking into account the reduction of the four wave mixing (FWM). The double impact of both ambient temperature and pressure effects are also investigated. The transmission technique is studied namely Soliton propagation technique. As well as two multiplexing methods are considered in the design namely ultra wide wavelength division multiplexing (UW-WDM) and ultra-wide space division multiplexing (UW-SDM). Based on experimental data, both the deep ocean water temperature and pressure are tailored as functions of the water depth. The product of the transmitted bit rate and the repeater spacing is processed over wide ranges of the affecting parameters.Keywords Four Wave Mixing, Submarine Systems, Multiplexing Techniques, Soliton Propagation and Undersea Depths
