SQS has many years of experience in the design and production of optical fiber feedthroughs for vacuum applications. Vacuum fiber feedthroughs are suitable for use in various areas of research and development, and in many industrial applications.

Vacuum fiber feedthroughs are manufactured according to specific customer requirements. We can seal the majority of optical fibers in standard or atypical flanges for various areas of feedthrough applications.

The manufacturing process and materials used allow us to offer vacuum fiber feedthroughs suitable for high and ultra-high vacuum levels with 10−10 to 10−12 mbar.l/s. Fiber feedthrough outputting optical fibers may be mechanically protected by tubing and terminated with various types of optical connectors ( FC/PC, FC/APC, SMA905, …).

Fiber feedthroughs are designed so that the sealing of optical fibers does not affect transmission parameters of an entire route. The feedthrough construction ensures time stability of transmission parameters in all operating conditions.

Design:

  • many types of sealing material (glass, adhesive)
  • Single Mode or Multi Mode fiber
  • many types of flange (KF, CF, custom requirement)
  • many types of connectors (FC/PC, FC/APC, SMA905, …)

Applications:

  • vacuum chambers
