Optical fibers can be classified into single-mode fiber and multimode fiber according to transmission mode, ultraviolet fiber, observable fiber, near-infrared fiber and infrared fiber according to working wavelength, conventional single-mode fiber and dispersion-shifted single-mode fiber according to optimal transmission frequency window, step fiber, near-step fiber, graded fiber and other fibers according to refractive index distribution, and Shi Ying fiber, multi-component glass fiber, plastic fiber and composite fiber according to raw materials.
