“…Increasing the sensor count requires complex application-specific sensor array designs or spatial multiplexing using multiple fibers [4]. Remote sensing using optical amplification has opened up new possibilities to fiber sensing [5]. To our knowledge, the longest reported system covers 230 km for a single strain FBG sensor, using Er-doped amplifiers [6].…”

This work is meant to provide a review of different multiplexing topologies employing distributed erbium-doped fiber and Raman amplification to solve the problem of powerloss compensation in fiber-optic sensor (FOS) networks. This is a key parameter in large multiplexing networks, particularly when employing intensity-modulated sensors. These topologies are studied both theoretically and experimentally, and a comparative analysis is carried out between them. The main parameters considered in the analysis are power budget, optical signal-tonoise ratios, scalability and architecture complexity.Comparison of the measured optical spectrum of amplified single and double bus networks for sensor multiplexing.

“…Interferometric sensors were used in these arrays and sophisticated addressing/interrogation techniques were developed which permitted to achieve unprecedented detection performances [6]. With the military pressure release as a consequence of the end of the Cold War, this technology was adapted to other applications, most notably the monitoring of the ocean continental platforms and the elaboration of seismic maps of the sea floor [7]. Nowadays, these seismic maps are essential for the permanent monitoring of oil and gas reservoirs, which is achieved analysing the propagation of seismic waves induced by controlled explosions.…”

This presentation gives a review of the main concepts behind fibre optic sensing networks. Some important application areas are mentioned, such as the monitoring of oil fields, of large Civil Engineering structures, as well as of natural environments. Then, it will be addressed the potential relevance of this technology in domains of increasingly social importance, such as Health and Elderly Care, particularly in the development of Personal Health Systems.

“…Currently, the practical optical fiber hydrophone system is based on the optical fiber interferometer technology. A multi-wavelength narrow linewidth laser or a laser array composed of multiple single-wavelength narrow linewidth lasers, where the multiple wavelengths should be in the international telecommunication union (ITU) grid, is needed for the large scaled hydrophone array [3]. However, the laser array composed of multiple single-wavelength laser modules is always cumbersome and complicated in the configuration.…”

Abstract:A narrow linewidth laser configuration based on distributed feedback fiber lasers (DFB-FL) with eight wavelengths in the international telecommunication union (ITU) grid is presented and realized. In this laser configuration, eight phase-shifted gratings in series are bidirectionally pumped by two 980-nm laser diodes (LDs). The final laser output with over 10-mW power for each wavelength can be obtained, and the maximum power difference within eight wavelengths is 1.2 dB. The laser configuration with multiple wavelengths and uniform power outputs can be very useful in large scaled optical fiber hydrophone fields.
