With the rapid growth in the telecommunications industry moving towards 5Gand beyond (5GB) and the emergence of data-hungry and time-sensitiveapplications, Mobile Network Operators (MNOs) are faced with a considerablechallenge to keep up with these new demands. Cloud radio access network (CRAN)has emerged as a cost-effective architecture that improves 5GB performance. Thefronthaul segment of the CRAN necessitates a high-capacity and low-latencyconnection. Optical technologies presented by Passive Optical Networks (PON)have gained attention as a promising technology to meet the fronthaulchallenges. In this paper, we proposed an Integer Linear Program (ILP) thatoptimizes the total cost of ownership (TCO) for 5G using CRAN architectureunder different delay thresholds. We considered the Time and WavelengthDivision Multiplexing Passive Optical Network (TWDM-PON) as a fronthaul withdifferent splitting ratios.

Planning a Cost-Effective Delay-Constrained Passive Optical Network for 5G Fronthaul
