Optical glass fiber is a type of glass that is used in the telecommunications industry to transmit data over long distances. It is made of a core of glass surrounded by a cladding of glass with a lower refractive index. The core and cladding are usually made of silica, but other materials such as fluoride and chalcogenide can also be used. The core is typically surrounded by a buffer layer of plastic or other material to protect it from damage. The optical glass fiber market is driven by the increasing demand for high-speed data transmission and the need for reliable and secure communication networks. The market is also driven by the development of new technologies such as 5G and the Internet of Things (IoT). The optical glass fiber market is highly competitive, with many companies offering a wide range of products and services. Some of the major players in the market include Corning, Furukawa Electric, Sumitomo Electric, Prysmian Group, and OFS Fitel. Show Less Read more
