50G-PON-BASED DP-QPSK TECHNIQUE BY UTILIZING THE MILLIMETER FREQUENCY SPECTRUM

Abstract

For the fifth generation (5G) broadband fronthaul network, the architecture of the 50 Gbps passive optical network (50G-PON) is provided. This research makes use of a quadrature phase shift keying (QPSK) structure with a coherent receiver network and the dual polarization (DP) idea. In order to maximize band usage, the millimeter wave at 32 GHz is modulated over 50G DP-QPSK that spans a 60 km fiber span. A more effective technique to utilize millimeter wave in the high spectrum region for mobile broadband is through passive optical network solutions. The performance is assessed using the constellation figure and signal spectra.
