Optical Fiber An optical fiber is a thin, flexible, transparent strand of glass or plastic used to transmit light signals over long distances with minimal loss or attenuation. Optical fibers consist of a core surrounded by a cladding layer, which has a lower refractive index to facilitate total internal reflection of light within the core.
Optical fibers are widely used in telecommunications, data networking, and sensing applications to transmit digital data, voice signals, and video streams at high speeds and bandwidths. They offer advantages such as low signal loss, immunity to electromagnetic interference, and high data transmission rates compared to traditional copper cables. Optical fibers are also used in medical imaging, industrial sensing, and laser delivery systems due to their flexibility, durability, and ability to transmit light over long distances without significant degradation. |
