The growth was improved by the successive introduction of Wavelength- Division Multiplexing (WDM) technique, Polarization-Division Multiplexing (PDM) technique, and higher-order modulation formats known. At the same time their capacity continuously grew by three orders of magnitudes. Single-Mode Fibers (SMFs) have been successfully exploited for long-distance optical transmission for over the decades.
Optisystem provides Visualizer library consisting of spectrum analyzer, time domain visualizer, power meter, WDM analyzer, Oscilloscope visualizer, etc, which will be helpful in verifying whether the signal has been transmitted efficiently via Few-mode fiber from transmitter section to receiver one with significant flexibility.

Here in this paper, the authors use Optiwave’s Optisystem software for carrying out required simulations. A Coherent implementation differs from previous work in optical MIMO by allowing the system to tolerate smaller modal delay spread yet maintains the necessary diversity needed for MIMO operation.
The authors present a Multiple-Input Multiple-Output (MIMO) optical link based on coherent optics and its ability to exploit the inherent information capacity of a multimode fiber. This paper, inferred the transmission of 6 spatial and polarisation modes, each carrying the quadrature-phase-shift-keyed channels over few- mode fiber keeping lower differential group delay. As we know that the capacity limits of single mode fiber has almost reached its maxima, Space Division Multiplexing can be helpful for increasing the data rate requirement.
