The optical fiber is short for an optical waveguide fiber, and is a light transmission tool adopting the principle of total reflection of light in fibers made of glass or plastics.

Currently dimensional optical waveguide fiber crown and plastic hose and other products have been exported to Poland, India, Canada, Russia, New Zealand, Australia and other countries and regions.

This produces a "waveguide," which functions like a one-atom-thick fiber optic cable.
