How we shape the telecommunication industry

Since the 1970's, Heraeus has helped shape the telecommunication industry. We supplied our quartz tubes to AT&T for development of the MCVD process to initiate application of optical fibers for telecommunication. We later built a factory in the US to supply the growing demand of these tubes. In parallel we developed a large batch synthetic quartz process and combined it with our invention of the online RIC® system, enabling easy and efficient fiber draw from large preforms. Read more about early developments in optical fiber, challenges for today's fiber producers and technologies of the future.
