“…There have been many studies of how to ensure survivability of telecommunications fiber networks and sensor radio networks. However, depending on their topologies, the most representative robust fiber-optic sensor systems can be classified as: ring networks [51], [52], [53], double ladder bus [42], [48], [49], [54], [55], linear fiber laser [56], [57], [58], [59], and mesh sensing systems [52], [60], [61], [62], [63] each one with their own pros and cons. So, the choice of a protection scheme is determined by the performance, cost and final application of the network.…”

One of the main goals in fiber optic sensor technology is to multiplex together a high number of sensors in the same network in order to share expensive terminal equipment and develop a system including multiple measuring points. Different kind of multiplexing networks for fiber optic sensors will be described and compared here, including networks using optical amplification and lasing multiplexing systems. State of the art in multiplexed and distributed sensor networks is also shown, focused on robust, remote and distributed Brillouin networks.

“…In order to overcome this drawback, a number of mesh sensing systems to support more comprehensive sensing areas have been recently proposed and experimentally demonstrated [43,44]. Furthermore, a number of novel optical add-drop multiplexers (OADMs) for WDM mesh networks have been also investigated [46]. In these topologies, based on the characteristics of a thin-film filter and an optical switch, the optical signal blocked by single or multiple fiber link failures can be reconnected through logical backup pathways.…”

The ability to operate despite failure will become increasingly important as the use of optical sensor networks grows, and the amount of sensing information to be handled by a sensor network is increasing, especially for safety and security applications. In this review, the four categories of protection to allow service to be reestablished after a failure (dedicated/shared and line/path) are thoroughly discussed. This paper also presents an overview of the most representative robust fiber-optic sensor systems, discussing their schemes, pros and cons.

“…Upgrading the data rate of DWDM system using ADD/drop multiplexers along with couplers and the system data is converted from 20Gbps to 160Gbps at 180 km link length [5]. Analysis the performances of Wavelength Division multiplexing optical networks with two novels Add/drop multiplexers along using with self-healing techniques for making network reliable [6]. Designing of selfhealing access ring networks in DWDM system with cost saving, cross talk free with using bi-directional optical Add/drop multiplexers (OADM) in single fibre and finds that this architecture simplifies the hub complexity and also by using this networking model low cost components are employed at each node [7].…”
