Temperature Fiber Optic Sensor Design
This paper reviews the sensing principle, structural design, and temperature measurement performance of fiber-optic high-temperature sensors, as well as recent significant progress in the transition of sensing solutions from glass to crystal fiber. Optical fiber-based temperature sensors have played a crucial role in this decade to detect high fever and tackle COVID-19-like pandemics. This makes them suitable for use in space applications and hazardous environments such as high-voltage machinery (e., generators, motors, transformers), nuclear power. Traditional point sensors provide temperature data at a single location,limiting the ability to capture a complete picture of thermal distribution. This is where Sensuron's Fiber Optic Temperature Sensing Systems come into play.

Bending radius during optical cable laying
The bend radius of fiber cables is critical for maintaining high performance and longevity. During installation under tension, maintain a minimum bend radius of 20 times the cable's outer diameter, while post-installation requires a minimum long-term bend radius of 10 times the. Bending of a fiber optic cable can damage the cable if the curvature of the bend is too small.

Bending the fiber optic cable reinforcing core
Excessive bending can deform or break the fiber core, which is only about 125 microns thick. It is measured from the inside of the bend, not the outer curve. Fiber optic cables transmit data through light propagation within a glass core. Proper bend radius control ensures the integrity of optical performance and protects the glass. All fiber optic cables have specifications that must not be exceeded during installation to prevent irreparable damage to the cable. and comments on important warranty issues re-lated to handling.

Design of Fiber Bragg Grating Demodulator
To achieve synchronous demodulation of a large-capacity Fiber Bragg Grating (FBG) sensor network, a FBG demodulation system based on modulated grating Y-branch (MG-Y) tunable laser is designed, combining wavelength division multiplexing and space division multiplexing technologies. In this paper, a novel demodulation algorithm based on the variable-step-size method and cross-correlation algorithm is proposed to demodulate the wavelength of an FBG.
