Fiber optic sensing technology is divided into point-type and
Optical fiber sensing can be broadly classified into two types: point type, and distributed type. Point-type sensors are specially processed on optical fiber lines to function as sensors. A typical example is the Fiber Bragg Grating sensor. The distributed type uses technology making the entire. Radiation absorption excites an orbital electron to a higher energy level. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system.

Quasi-distributed fiber optic sensing technology
Quasi-distributed sensors enhance coverage by multiplexing multiple FBGs through time-division or wavelength- division schemes, enabling efficient long-distance monitoring. Optical sensors have emerged as vital tools in modern sensing technology owing to their sensitivity, immunity to electromagnetic interference, lightweight structure, and capability to operate under harsh environmental condition, By employing optical fiber as both transmission and sensing media. The Fiber Optic Sensing Association (FOSA) is dedicated to accelerating the use of distributed and quasi-distributed optical fiber sensing technologies. Fiber optic sensing works by measuring changes in the “backscattering” of light occurring in an optical fiber when the fiber encounters vibration.

WDM is a key technology in fiber optic communication
Wavelength Division Multiplexing (WDM) allows multiple optical signals to transmit over a single fiber by using different wavelengths of light. It increases fiber network capacity without requiring additional fibers, making it essential for modern optical communication. This technique enables bidirectional communications over a. It's called wavelength division multiplexing (WDM), and WDM in optical fiber communications carries great potential to help network operators stay ahead of growing demands for bandwidth. Think of light passing through a prism: You've probably seen the rainbow that materializes as the light splits. WDM stands for wavelength division multiplexing.
