👉 Whitings are a type of optical fiber that is used in high-speed communication networks. They consist of a single strand of glass fiber that is coated with a special material called "white light" (such as phosphor) and placed over a thin layer of glass between two strands. The white light acts like a filter, allowing only specific wavelengths of light to pass through the fiber while blocking other wavelengths. This allows high-speed data transmission over long distances without the need for additional cables or amplifiers
