Among the various materials for industrial use, quartz glass is the material with the best light transmittance so it is commonly used for optical fibers for communications. Quartz-type optical fibers have little transmission loss so they are widely used in broadband long-distance transmission communications.
Main features
- Good light transmittance
- Small transmission loss
Applications
- Substrate tubes in the optical fiber manufacturing processes of modified chemical vapor deposition (MCVD) and plasma-enhanced chemical vapor deposition (PCVD)
- Jacket tubes used in the jacketing ("sleeving") process used in the production of cladded portions
