New type of optical fiber FTTH
The conceptually simplest optical distribution network architecture is direct fiber: that is, each fiber leaving the central office goes to exactly one customer.

Fiber intensity modulation type sensor
Intensity modulation-based polymer optical fiber (POF) RI sensors have a lot of advantages including low cost, easy fabrication and operation, good flexibility, and working in the visible wavelength. In this review, recent developments of the intensity modulation POF-based RI. A reflective intensity-modulated fiber-optic sensor based on microelectromechanical systems (MEMS) for pressure measurements is proposed and experimentally demonstrated. The sensor consists of two multimode optical fibers with a spherical end, a quartz tube with dual holes, a silicon sensitive. Intensity-modulated sensors were defined in Chapter 2 as sensors that detect the variation of the intensity of light associated with the perturbing environment.

3D Fiber Optic Vibration Sensor
In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferometric sensing technology, such as Sagnac, Mach–Zehnder, and Michelson, to backscattering-based sensing technology, such as phase-sensitive optical time domain. The fiber optic sensing technology provides data support in structural health monitoring of the macro facilities, including design, construction, and maintenance of bridges, tunnels, ports and other infrastructures. The 3D-Fiber from the SMART series allows precise, non-contact vibration measurements in three dimensions using a single device that integrates multiple functionalities.

French Fiber Optic Winding Tube Remote Monitoring Type
Fluorescent fiber optic temperature monitoring systems based on GaAs sensing technology offer direct, en temps réel, and high-voltage-immune winding temperature measurement. In transformers, a Winding Temperature Indicator (WTI) is a crucial instrument for monitoring the temperature of the windings, which are the coils of insulated wire that carry electrical current. Traditional WTIs have been serving in the industry for a very long time but, they highly rely on. The technology used leverages fiber-optic sensors to provide real-time and accurate temperature measurements, overcoming the limitations of traditional methods such as RTDs (Resistance Temperature Detectors) and thermocouples, have limitations in terms of accuracy, sensitivity, and susceptibility.

Principle of Fiber Optic Sensor Controller
Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required.
