ABSTRACT
Internet traffic and the number of devices is growing at an exponential rate. A robust communication network is required that provide high-capacity communication and integrate wired and wireless communication devices without creating bottlenecks. This work proposes a passive optical network (PON) architecture to ensure high-capacity paths between the densely deployed remote radio units (RRUs) with baseband units (BBUs) in 5G network architecture. Orthogonal frequency division multiple access (OFDMA) and wavelength division multiplexing (WDM) techniques are employed to ensure high capacity. Furthermore, free space optical (FSO) links are employed at the distribution level (DL) to facilitate dense deployment of RRUs near the subscriber’s premises. The proposed model is analyzed in Optisystem, and it is observed to support 40 Gbps of data, over 4 km length of FSO.
