Glass & Optical Fiber

Fabricate high-purity preforms & draw low-loss glass and optical fiber

Consistency and repeatability in high-purity glass processing environments are critical to ensure that the millions of kilometers of glass and optical fiber manufactured each year can maximize transmission and enable us to build the infrastructure for 5G.

Using mass flow rather than standalone valves to control inert, shielding, and dopant gases enables full system visibility and control.

  • Automatic adjustment to ambient atmospheric conditions. An unexpected weather event or change to barometric pressure won’t lead to lost batches at your outdoor draw towers.
  • Full batch-to-batch repeatability. Mass flow control means consistent fuel and shielding gas delivery, for a consistent final product every time.
  • Lowest lifetime cost of ownership. Preventative maintenance metrics built in, industrial communication options for full visibility, and all-around device flexibility mean you need fewer spares without compromising operational precision.

Maintaining purity with tight process control of fuel and shielding gases

Mass flow control of dopant gases ensures that all impurities are removed during preform manufacture and polishing. Pressure control enables smooth ribbon coating to ensure the right amount of polymer is dispensed.

Small footprint can be designed designed specifically to your glass lathe.

Maximizing transmission to build the 5G network

Removing and recovering gases for high-purity or specialized preforms using multivariate devices lets you monitor and control various system parameters simultaneously, resulting in the highest degree of repeatability and consistency.

Rapid response & control times let you introduce new lines without affecting the supply pressure to the existing lines.

Improving system visibility & control

Smart controllers with EtherNet/IP, Profibus, or another industrial communication protocol introduce your flow and pressure data into your overall control system.

Multivariate data monitoring and collection means continuous improvement using real-time analytics.

Lowest lifetime cost of ownership

Mass flow and pressure control aid in processes including cooling glass, ribbon coating, preform polishing, and lathe control. Precision, repeatability, rapid response, and automation combine for instrumentation to improve end-to-end optical fiber & glass manufacturing.
