Design of high capacity 5.76 Tbits/s SDMPDM-Nyquist superchannel WDM hybrid multiplexing in 3.1% Germania doped MMF

Abstract

To dispatch the goal of walking towards the 4th
Industrial Revolution, one of the main key materials that require
alterations and enhancements is data communication and
transmission. To keep up with the augmented rise in demand for
data, fiber optics communication and networks commence a
significant role in the transfer of data at high speeds. This article
exemplifies the expediency analysis of 5.76 Tbits/s SDM-PDMNyquist superchannel WDM hybrid multiplexing technique over
a multimodal transmission link up to 10 km using C-band carrier
frequencies. This system is designed to carry 48 channels of data
that can be produced using 8 C-band carrier frequencies, 2
polarization states, and 3 LP modes through 3.1% Germania
doped over pure silica step-index multimode fiber. The system
exhibits a satisfactory performance (log BER -9.35, faithful Qfactor 6.09, extinction ratios 7.78, minimum OSNR 46.5 dB) up to
a distance of 10 km. Each channel receives a satisfactory amount
of power after the dual-stage amplification process in the
transmission medium with an ultra-high spectral efficiency of
137% and a high bandwidth-distance product of 385 MHz.km.
