PM Vacuum Fiber Optic Feedthrough with Adapter

PM Vacuum Fiber Optic Feedthrough with Adapter

We have expanded our portfolio of vacuum feedthroughs. Now we are offering such an adaptor featuring feedthroughs, which are able to seal polarization maintaining fiber (PMf) within themselves with minimum insertion loss and maximum extinction ratio.


These feedthroughs are set...

Hermetic Fiber optic feedthroughs

for vacuum and high pressure applications

SQS Vláknová optika SQS Vláknová optika has a long time experience with manufacture of customized fiber optic feedthroughs and their consequent assembly into specific flanges. Sealing technology of fiber in a feedthroughs enables their use in extreme vacuum or high pressure applications as well as provides for their inertness to many different oils and gasses.

We manufacture feedthroughs with single-mode, multi-mode or polarization maintaining fibers.

Manufactured feedthroughs undergo strict specification inspection and their optical parameters must comply with IEC, CENELEC and Telcordia standards. Feedthroughs are offered with adapter or pigtail type interfaces.

Vacuum fiber optic feedthroughs with adapter interface

SQS Vláknová optika SQS Fiber Optics

  • A feedthrough is interfaced with a flange via O-rings which ensures its easy replacement in a flange due to its damage or due to a need for the use of different fiber in a feedthrough
  • Easy replacement of ferrule’s sleeve inside the adapter on both ends of a feedthrough
  • We offer standard as well as custom flanges of requested material
  • Operating temperature range from - 40°C /+85°C to -40°C /+180°C
  • Suitable for applications in ultra-extreme vacuums

Vacuum fiber optic feedthroughs with pigtail interface

SQS Vláknová optika SQS Fiber Optics

  • Made with single-mode, multimode or polarization maintaining fibers
  • Arbitrary input and output fiber lengths
