Abstract ultimate optical transmission of 10,000 channels huge submarine cables has been investigated under different depth conditions. forwad raman amplification technique is considered taking into account the reducation of the four- wave mixing.the double impact of both temperature and pressure is investigated.three transmission time division multiplexing are studied namely soliton,nonlinear and maximum time division multiplexing. also two multiplexing methods are considered in the design. |
