Cost-Efficient High-Capacity Radio Over Fiber (RoF) Transmission: Integrating Coarse and Dense WDM Techniques

Abstract

Using Radio over Fiber (RoF) has expanded lately to the point where a key component of it link between central office and base station would be useful from the whole industry. As the market grows towards communication products of ultra-high-speed, like 5G applications, capital expenditure (CapEx) is crucial. The two primary types regarding wavelength division multiplexing (WDM) techniques Dense WDM and Coarse WDM are integrated in the presented work to create cost-effective, new design paradigm for RoF. The suggested system is tested and put into use at 10 Gbps data transmission rate. In addition, it describes how the two systems-based evaluations performed in terms of transmission distance, eye diagram analysis, minimal Bit-Error-Rate (BER), and power levels. The research's conclusion presents a result which demonstrates how Coase WDM-based RoF system reduced CapEx by 18% while delivering a balanced performance in comparison to Dense WDM-based RoF. The results show that Coase WDM maximizes the usage regarding Optical Signal-to-Noise Ratio (OSNR) to 75 dB while being an economical method for short-haul meter links. Massive centralized baseband units connected to the expansion of (5G/6G) networks will employ this novel combination of dense as well as coarse-WDM systems.
