Definition of non-communication fiber:

· Non-communication optical fibers are optical fibers used in fields other than communications.

· Non-communication optical fiber is based on the principle of optical fiber to realize light transmission, image transmission sensing, is widely used in industry, military industry, scientific research, medical other industries.

· Non-communication optical fibers are used for shorter distances, with lengths ranging from a few millimeters to hundreds of meters.

· According to the core material, non-communication optical fibers can be divided into: multi-component glass optical fibers, quartz optical fibers, polymer optical fibers, liquid core optical fibers, hollow core optical fibers, crystal optical fibers, etc.
