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 Specification options:
SMA905 or FC/APC adapter interface
Pigtailed terminations according to customer specifications
PM, SM and MM fiber types
Low insertion loss
HV and UHV compatible
