Fiber Closure Manufacturers Share The Composition Of Optical Fibers
Today, what does Fiber Closure manufacturers share about fiber optics?
Optical fiber, also known as light guiding fiber and optical fiber, is a fiber that closes light energy in the fiber to produce light guiding effect. It can transmit signals such as light and darkness of light and change of light and light from one end to the other. An optical fiber is a composite fiber produced by a special composite technique from two or more transparent materials having different refractive indices. Its basic type consists of a core material that actually acts as a light guide and a skin layer that closes the light energy in the core material. There are various classification methods for optical fibers: glass, quartz and plastic optical fibers can be divided into flexible and inflexible optical fibers according to shape and flexibility; and core-shaped and self-assembled according to fiber structure. Type (also known as gradient type); according to the transferability is divided into light transmission and transmission optical fiber; according to the wavelength of the transmitted light is divided into visible light, infrared, ultraviolet, laser and other optical fibers.
The communication of optical fiber mainly uses the high coherence of laser, and uses its coherence to convert information into light intensity signal, and then further convert it into digital signal.
Optical fibers are generally used in the form of bundles, cables, plates, tubes, and the like. There are many inner cores and coating materials for the manufacture of organic light guiding fibers, some of which are covered with a layer of polyethylene or other materials of different refractive index (such as polytetrafluoroethylene) on polymethyl methacrylate fibers, and others The acrylonitrile resin covers the acrylic core yarn.
When selecting a substrate of an optical fiber, it is generally required that the light transmittance of the core material is high, and the coating material requires a low refractive index, and it is required that the difference in refractive index between the core material and the coating material is as large as possible. In terms of thermal performance, it is required that the thermal expansion coefficients of the two materials are close to each other. If the difference is large, the formed optical fiber generates internal stress, which lowers the light transmittance and the fiber strength. In addition, it is required that the softening point of the two materials and the viscosity at high temperature are close to each other. Otherwise, the bonding of the core material and the coating material will be uneven, which will affect the light guiding performance of the fiber.
