Synthetic Quartz Glass for Fiber Optics

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.

Synthetic quartz glass for optical fibers

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
