Vacuum hybrid feedthroughs are available with FC and SMA905 adapter interfaces and with many kinds of optical fibers (SM, MM and PM). Optical fiber may be protected by PTFE tubing or by flexible stainless steel braiding.
Vacuum hybrid fiber feedthrough can be completely disassembled and thus easily replaced within its housing flange or as part of flange within mounting wall.
Hybrid feedthroughs are available with pigtailed terminations on natural air pressure side or on vacuum side and are shipped either as standalone items or as pre-mounted in standard or customized flanges.
Product design options:
- SMA905 or FC adapter interface
- Pigtailed terminations according to customer specifications
- PM, SM and MM fiber types
- Low insertion loss
- HV and UHV compatible
- Stable within specified temperature range
- Shipped as standalone item or in KF or CF flange
