This research paper introduces an advanced optical transmission technology for 5G+ networks that uses high-order quadrature amplitude modulation (QAM) to improve data delivery.
The system uses coherent optical transmission, dual-polarization, advanced DSP algorithms, and FEC to achieve great spectral efficiency, signal integrity, and resistance against optical defects at 16Tbit/s per channel across 200 kilometers. This study shows that high-order QAM can address future connectivity needs and advances optical network development for 5G and beyond. Based on the system developed by the author with a speed of 1 Tbit/s and the application of the Il’in-Morozov’s method, the presented system can be modernized and simplified in its structure, brought to the speeds indicated above due to stream aggregation.
