Fiber Optical Preforms

Fiber Optical Preforms

 

Optical fiber preform is the core raw material for manufacturing quartz series optical fiber. Preforms generally have a diameter of a few millimeters to tens of millimeters (commonly known as light rods). The internal structure of the fiber is formed in the preform. The production of preforms is the most important part of fiber optic technology.

People must first make optical fiber preforms when making optical fibers. There are many methods for producing optical rods. The commonly used production process is gas phase oxidation. In the gas phase oxidation process, the vapor of high-purity metal halide reacts with oxygen to form oxide particles, which are deposited on the surface of the glass or quartz body (or the inner wall of the tubular body) and then formed by sintering. The transparent glass rod (if it is tubular, it also shrinks to become a rod), so that the light rod is made. At this time, the optical rod already has the basic structure of the optical fiber, and the bare fiber pulled out by the drawing machine includes the core and the cladding. In order to protect bare glass fiber, optical fibers are protected from external substances such as light and moisture. When the fiber is drawn, it is coated with an elastic coating (coating layer). The optical fiber is composed of a core, a cladding and a coating layer. The light guiding part is a solid core on the axis. The function of the cladding is to provide a cylindrical interface so as to bind light in the core. The coating is a resilient, wear-resistant plastic material that enhances the strength and softness of the fiber.
