Abstract
We will review physical and economic benefits of space division multiplexing (SDM) in submarine transmission. While multicore and multimode technology is still in research stage, SDM principles could be applied today using a multiplicity of single mode fibers. When power is limited, SDM approach allows one to achieve a significantly higher cable capacity compared to the traditional approach of maximizing per-fiber capacity. When looking at systems economy, SDM allows one to obtain the best cost per bit for the whole cable. This is achieved through optimization of number of spatial paths and sharing the pump power between the fiber paths.
