Investigation of OWC System Incorporating Different Filters

Optical wireless communication (OWC) system is growing quite fast these days due to its potential applications in 5G wireless networks. A 4×10Gbps OWC system is designed and investigated incorporating Rectangular, Butterworth and Bessel filters over long reach at 4×10Gbps data rate. Simulation results indicate that the system utilizing Rectangular filter shows better performance than Butterworth and Bessel filters. It offers 90km range at 40Gbps traffic rate. Also, the system can tolerate maximum 5 and 3µrad pointing errors at transmitter and receiver respectively. Moreover, optimum performance can be obtained for the proposed architecture over existing works.
