Design, availability and reliability analysis on an experimental outdoor FSO/RF communication system

This work highlights the characteristics of an experimental outdoor free space optical (FSO) communication system combined with a redundant radio frequency (RF) link that provides high availability and uninterrupted communication even in adverse weather conditions. The system provides wireless connection between the two of the five campuses of Ankara University. The rationale behind the selection of design parameters is given and the structure of the hybrid system is outlined. Results, regarding the link availability of the system, which has been operational for over 2 years, are presented.
