  • Optical fiber is used for wireless communication

    Optical fiber is used for wireless communication

    Immunity to Interference: Optical wireless systems are resistant to interference. Higher Data Rate: They offer higher data rates due to the large bandwidth available on fiber cables. An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other. Such fibers are widely used in fiber-optic communication, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than. Fiber-optic communication is a form of optical communication for transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. The cladding's refractive index is slightly smaller than that of the core, which confines light within the core and propagates by repeated total reflection at the boundary with the. Optical fiber is a highly-transparent strand of glass that transmits light signals with low attenuation (loss of signal power) over long distances, providing nearly limitless bandwidth.
