Transmission Capacity Improvement of Ultra Wide Wavelength Division Multiplexing (UV-WDM) Submarine Fiber Cable Systems for Long Haul Depths

Optical Submarine Cable systems play a principal role in international telecommunications, thanks to their superiority over satellite systems in terms of stability, latency and upgradability. The business of constructing and then maintaining and selling capacity over submarine fiber optic cables is fascinating, and is absolutely fundamental to modern day communications. The sector has its own unique challenges due to the extraordinarily rapid pace of development in transmission technologies as well as the timescales and levels of investment required to build new systems. In the present paper, ultimate optical transmission of ultra multi channels huge submarine cables under different depth conditions has been investigated over wide range of the affecting parameters. The double impact of both temperature and pressure is also analyzed. We have employed multiplexing technique namely UW-WDM to be merged number of 10000 transmitted channels on the same submarine optical transmission links respectively. Based on experimental data, both the deep ocean water temperature and pressure are tailored as functions of the water depth. As well as we have taken into account the estimation of the total cost planning and transmission data rate capacity of the submarine fiber cable system for this multiplexing technique under study.
