A Mach-Zehnder interferometer (MZI) for high temperature (1000℃) sensing based on few mode fiber (FMF) was proposed and experimentally demonstrated. The sensor was fabricated by fusing a section of FMF between two single-mode fibers (SMFs). The structure was proven to be an excellent high temperature sensor with good stability, repeatability, and high temperature sensitivity (48.2 pm/℃) after annealing process at a high temperature lasting some hours, and a wide working temperature range (from room temperature to 1000℃). In addition, the simple fabrication process and the low cost offered a great potential for sensing in high temperature environments.

“…Most of the previous research on RMS and sensor-based solutions have used a literature review as their main methodology, and they tend to be more technical and place less focus on service opportunities or the business value of the solutions (Kurada and Bradley, 1997;Everall et al, 2000;Sion and Atkinson, 2002;Owen et al, 2009;Vogl et al, 2009;Bogue, 2013;Gomes et al, 2013;Huang et al, 2014). However, some valuable single case studies have focussed on applying RMS to monitor an installed base of equipment at the customer's location (Nieva, 1999;Mori et al, 2008;Jonsson et al, 2009;Westergren, 2011;Westergren and Holmström, 2012), open innovation and trust as a key precondition for openness between the manufacturers and customers (Westergren, 2011;Westergren and Holmström, 2012), the use of IT solutions to provide value-adding services in industries, and the role of customers to become either cocreators of value or receivers of the created value (Jonsson et al, 2008(Jonsson et al, , 2009Kowalkowski and Brehmer, 2008).…”

Purpose The purpose of this paper is to better understand the efficient use of remote monitoring systems (RMS) to create business value for industrial services in manufacturing firms. A business view to RMS is a key prerequisite for the successful application of the Internet of Things (IoT) in industrial services. Design/methodology/approach A qualitative multiple-case study was conducted in six engineering companies. The main source of data was semi-structured interviews with 16 managers. Findings The findings highlight the role of RMS in enabling manufacturing firms to collect data from customers to complement their limited knowledge about their customers. The study demonstrates the business value of using RMS in industrial services and the necessity of capturing the business value through advanced IT technologies. Research limitations/implications The qualitative research design and choice of six target companies limit the findings to business-to-business manufacturing firms. Further, the focus is on the manager’s viewpoint. The findings imply new business value through an efficient use of RMS to complement direct customer contact. Practical implications The study draws attention to the skilled use of advanced RMS and information and communication technology as a prerequisite for the successful application of the IoT in manufacturing firms that provide services for complex solutions and customers dispersed globally. Originality/value The research shows that using information collected through RMS is an important factor in creating business value in a manufacturing firm’s customer relationships. The study contributes by integrating RMS into the customer information collection process to increase the amount, validity and quality of data.

“…The single mode-few mode-single mode (SFS) fiber structure filter is also a typical optical filter and has been widely used in fiber sensing in recent years [26][27][28][29][30][31]. In this paper, we will show that the SFS fiber structure filter can also work as an all-optical temporal differentiator.…”
