Simulative study of optical digital signal processing based space/mode division multiplexing system with elevated hybrid ultra wide-band EDFA/Raman/EDFA amplification over SDM/few mode fibers

This paper has highlighted the simulative study of optical digital signal processing based space/mode division multiplexing system with elevated hybrid ultra wide-band EDFA/Raman/EDFA amplification over SDM/Few mode fibers. Possible transmission system distance is measured in relation to the signal attenuation for SDM/FMF fibers through different pumping power levels at the same operating simulation parameters. As well as the possible system bit rate is demonstrated against the signal dispersion coefficient for both SDM and few mode fiber (FMF) fibers through different levels of the pumping power. Optical signal per noise ratio per channel, optical received channel power, signal per noise ratio at receiver, electrical received power at receiver, and overall system bit error rate are clarified against various pumping power levels with SDM/FMF fibers at the optimum signal attenuation/dispersion coefficient under the same operating simulation parameters. Possible transmission distance is indicated in relation to different signal attenuation levels with SDM and FMF fibers in the presence and absence of amplification under the same operating simulation parameters. Moreover, possible transmission bit rate per channel is demonstrated in relation to different signal dispersion levels with both FMF and SDM fibers across with/without amplification under the same operating simulation parameters.
