Hi Dhiman,
I think at present we can implement SDM in Optisystem.
Although the use of multiple parallel optical paths in the form of space division multiplexing/spatial division multiplexing (SDM) is seen as the way forward. SDM is implemented through the use of Multiple Fiber arrays, Multicore Fibers (MCF), Multimode Fibers (MMF) and Few Mode Fibers (FMF) to increase the available bandwidth.Parallel data transmission through spatial multiplexing also has significant applications in short range communication, where the component simplicity and reduced cabling costs associated with SDM can offer significant advantages in data-centre interconnects.
thanks,
