Valokuitusäie

Valokuitusäie, often translated as optical fiber or fiber optic cable, is a thin strand of glass or plastic used to transmit light signals. These fibers are typically very thin, often thinner than a human hair, and are enclosed in protective layers. The principle behind valokuitusäie is total internal reflection, where light entering the fiber is bounced back and forth within the core, allowing it to travel long distances with minimal loss of signal strength.

The primary application of valokuitusäie is in telecommunications, where it forms the backbone of modern internet and telephone networks. Its ability to carry vast amounts of data at high speeds makes it superior to traditional copper wiring for long-distance communication. Beyond telecommunications, optical fibers are used in medical imaging, where they can be inserted into the body to view internal organs, and in various industrial sensing applications. The manufacturing process involves drawing molten glass or plastic into extremely fine threads, ensuring uniformity and purity for optimal light transmission. The development of valokuitusäie has revolutionized data transmission and continues to be a critical component in technological advancement.
