JELE_V7_N3_RP5 Anshu Sharad Mohan Shrivastava Vikas Sahu Journal on Electronics Engineering 2249 – 0760 7 3 36 46 SDM (Space Division Multiplexing), MCF (Multi-core Fiber), FMF (Few Mode Fiber), DMD (Differential Mode Delay), IC-XT (Inter-core Crosstalk This paper aims to make understand the fundamentals and recent advancement in Multi-core Fiber Technology using Space Division Multiplexing. Few mode multi-core fiber (FM-MCF) that enable Space Division Multiplexing (SDM) have greater potential to improve the transmission capacity compared to (SSMF) Single Spatial Mode Fiber. The concept of Hetero geneous Few Mode Multi-core Fibers has paved its way in optical communication system replacing Homogeneous Few Mode Multi-core Fibers which were previously opted. In this paper, the authors have modeled MCF of different geometries with different specific parameters. The uncoupled multi-core fibers (MCFs) which can utilize multiple cores are arranged in a fiber as spatial transmission channels and then are used for the SDM transmission. Design of different structures with different number of cores are also demonstrated. Here, in this paper, the authors use COMSOL Multiphysics (5.2) for carrying out required simulations and MATLAB is used for generation of various proper graphs and field plots.
