100G-PON over dual polarized 16QAM by utilizing heterodyne-modulated millimeter eave for 6G fronthaul

The hasty progression in telecommunication industry on the route to the sixth generation (6G) introduces stringent necessities for durable photonic fronthaul communication networks. In this study, a photonic 100-Gbps centered passive optical network (100G-PON) transmission approach is presented for 6G fronthaul that leverages millimeter wave. A progressive digital procedure Dual-Polarization 16-Quadrature Amplitude Modulation (DP-16-QAM) is used to strengthen 6G fronthaul performance twice under dense collision whereas, heterodyne technique is employed via signal synthesis to generate 160[Formula: see text]GHz. The outcomes are observed in an optical band analyzer to validate the sub-THz spectrum, error vector magnitude (EVM), Q-factor and diminish the phase error rate for X–Y polarizer.
