What kind of optical fiber is suitable for sensors
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. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.

Is optical fiber made of crystalline material
Optical fiber consists of flexible glass or plastic strands engineered to transmit light. Manufacturers produce these fibers through a strict three-step process: preform fabrication, drawing, and coating. Such fibers are widely used in fiber-optic communication, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than. An optical fiber is a single, hair-fine filament drawn from molten silica glass. Currently. Crystalline materials are solids in which the atoms, molecules, or ions are arranged in a repeating pattern, known as a crystal lattice. This periodic arrangement gives crystalline materials their characteristic properties, such as optical transparency, high thermal conductivity, and specific. Single-mode fiber is made from a super-thin fiber core of glass or plastic, through which only one ray of light can travel at a time. The dopants are usually B20 3, P20 S, Ge02 or Ge02 - B203.
