“…simple technology, low production cost [11], light weight, and immunity to light source oscillations [12]. These features allowed for developments in multiple areas, and applications include fiber and nonlinear optics, laser physics [11], secure optical communications [13], random number generation [14], fiber fault detection [15][16][17][18][19], and sensing [20][21][22]. For sensing, optical random signals were used for compressive sensing [22].…”

“…An improved alternative to the well-known fiber cavity ring down technique was also proposed using random signals, creating a random correlation fiber loop ring down [12]. Random correlation was revealed to be a powerful tool to analyze more complicated systems where traditional interrogation techniques cannot be applied [18].…”

A brief review of new fiber microsphere geometries is presented. Simple microspheres working as Fabry-Perot cavities are interrogated in reflection and in transmission. Two microspheres were also spliced together, and subjected to different physical parameters. These structures are an alternative solution for load measurement and, when read in transmission, it is also possible to apply strain. Moreover, the structure is capable of being used under extreme ambient temperatures up to 900 • C. Random signal in cleaved microspheres was demonstrated with the possibility of using it for random laser or sensing applications. All this work was developed at the Centre for Applied Photonics, INESC TEC.

“…Therefore, the survivability of optical sensing and optical communication in OSNs in times of disaster is attracting wide-spread attention [22,23,24,25,26]. Moreover, optical sensing can help improve the survivability of optical networks [27,28]. In [27], the authors proposed optical chaos and hybrid wavelength division multiplexing/time division multiplexing (WDM/TDM) based on large capacity quasi-distributed sensing networks.…”

Optical sensing that integrates communication and sensing functions is playing a more and more important role in both military and civil applications. Incorporating optical sensing and optical communication, optical sensor networks (OSNs) that undertake the task of high-speed and large-capacity applications and sensing data transmissions have become an important communication infrastructure. However, multiple failures and disasters in OSNs can cause serious sensing provisioning problems. To ensure uninterrupted sensing data transmission, survivability has always been an important research emphasis. This paper focuses on the survivable deployment of OSNs against multiple failures and disasters. We first review and evaluate the existing survivability technologies developed for or applied to OSNs, such as fiber bus protection, self-healing architecture, and 1 + 1 protection. We then elaborate on the disaster-resilient survivability requirement of OSNs. Moreover, we propose a new k-node (edge) sensing connectivity concept, which ensures the connectivity between sensing data and users. Based on k-node (edge) sensing connectivity, the disaster-resilient survivability technologies are developed. The key technologies necessary to implement k-node (edge) sensing connectivity are also elaborated. Recently, artificial intelligence (AI) has developed rapidly. It can be used to improve the survivability of OSNs. This paper details potential development directions of survivability technologies of optical sensing in OSNs employing AI.

“…The cross-correlation algorithm is allowed for the development and demonstration of new technique with a low-cost and high precision for strain measurement system, however, multiplexing capability is still under restrictions. Recently, Yiyang Luo et al proposed a quasidistributed sensing system based on optical spectrum-limited chaos and CFBG [18,19]. Compared with CFBG, the identical weak FBGs can be used to significantly improve the multiplexing capacity of sensing system.…”
