Fibe is a bundle of optical fibers Fiber (from the French fibre) is a rope or string used as a component of composite materials, or matted into sheets to make products such as paper or felt. Fibers are often used in the manufacture of other materials. 

Fiber is a thin, flexible strand of a natural or synthetic material that is used in the production of textiles, ropes, and other products. Fibers can be classified into two main categories: natural fibers, which are derived from plants or animals, and synthetic fibers, which are man-made from chemical compounds.

In the textile industry, fibers are spun into yarns, which are then woven or knitted into fabrics. Fibers are chosen for their specific properties, such as strength, flexibility, insulation, and moisture wicking. Some common examples of natural fibers include cotton, wool, silk, and linen, while examples of synthetic fibers include polyester, nylon, and acrylic.
