Abstract 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.

To exploit the unprecedented opportunities offered by the E-Service Applications, businesses and users alike would need a highly-available, reliable, and efficient telecommunication infrastructure. This chapter provides an insight into building the next-generation network infrastructure, that is, the All-Optical Internet. It also reveals the factors driving the convergence of the Internet Protocol (IP) and the Wavelength-Division Multiplexing (WDM) technology. The chapter discusses the dominant optical networks architectures in an attempt to show the evolution towards the ultimate all-optical packet-switching network. A special focus is given to the Optical Burst Switching (OBS) as a new emerging switching paradigm and a highly promising technology. OBS network architecture, burst assembly, signaling and reservation protocols, QoS support, and contention resolution techniques are presented. Furthermore, realistic suggestions and strategies to efficiently deploy OBS are given.
