Abstract

The authors review the recent progress of Dense Space Division Multiplexing (DSDM) technologies using few-mode or multi-mode and multi-core fibers in this paper. It is shown that DSDM with high spatial density and large spatial multiplicity is effective for greatly expanding transmission capacity. In order to expand the capacity of the optical system, it has accelerated the development of high capacity DSDM transmission. The main objective of this project is to deploy a24 multi core fiber with 6 multi mode, thus achieving the high spatial channel count up to (N×M=144). An analysis has been carried out for low crosstalk (XT) and low differential mode delay. Also it has been observed for confinement electric field, effective mode index (n ), bending radius (R), core pitch (Δ), coupling coefficient (k).
