the OFC 11 ensures that nearly all introduced materials are effectively utilized in the preform. This results in higher yield per batch, reduced consumption of expensive raw materials, and less waste handling. For manufacturers, this means not only lower operational costs but also increased throughput, better resource efficiency, and a more sustainable production.
how to increase the productivity & yield in specialty preform production
with ferro-fluidic rotary joints, flexible gas configurations, and advanced process control
ferro-fluidic rotary joints
Provides exceptional leak-tightness and smooth, continuous rotation of the deposition tube under extreme vacuum and high-temperature conditions. These joints reduce the need for mechanical maintenance and minimize production interruptions, making them essential for high-throughput operations. Their ability to maintain stability ensures consistent layer formation during long deposition cycles.
gas configuration
Allow users to rapidly switch between gas types and flow profiles to accommodate different fiber designs and doping requirements. This flexibility reduces setup time, simplifies recipe changes, and supports the production of a broad range of specialty fibers without hardware reconfiguration.
process control and data logging
comprehensive monitoring of all key process parameters including gas flow, plasma power, and internal pressure. Real-time feedback enables immediate adjustments, reducing scrap rates and ensuring tighter process control. Historical data logging also supports quality assurance, traceability, and continuous process improvement.
