The simulation and investigation of a 32×10 Gb/s WDM all-optical bidirectional hybrid communication system for outdoor applications is presented in this article via multidisciplinary softwares. In order to track the system condition, a strain sensor based on ber Bragg grating (FBG) is integrated in-line with the ber optic link (FO-link). Then, a free space optical link (FSO-link) with 4-channel is simulated to act backup or rescue to the FO-link in the event of disaster or bombing. The FO-link is working well until the strain reach to 180 µε, after that the FO-link has degraded. Therefore, an optical switch is incorporated in between these systems (FO-link & FSO-link) to turn-on the FSO-link which act as a backup system to FO-link and maintains the continuity of the data transmission. According to the hybrid link results, there is an e cient enhancement in the Q-factor as compared with the FO-link even when there is heavy rain.

The simulation and investigation of a 32×10 Gb/s WDM all–optical bidirectional hybrid communication system for outdoor applications is presented in this article via multidisciplinary softwares. In order to track the system condition, a strain sensor based on fiber Bragg grating (FBG) is integrated in–line with the fiber optic link (FO–link). Then, a free space optical link (FSO–link) with 4–channel is simulated to act backup or rescue to the FO–link in the event of disaster or bombing. The FO–link is working well until the strain reach to 180 µε, after that the FO–link has degraded. Therefore, an optical switch is incorporated in between these systems (FO–link & FSO–link) to turn–on the FSO–link which act as a backup system to FO–link and maintains the continuity of the data transmission. According to the hybrid link results, there is an efficient enhancement in the Q–factor as compared with the FO–link even when there is heavy rain.
